Video Tutorial

Many bgm innovations were part of our Platonica project, in this video you can see them Disc brake and the brake caliper mount im bgm Tutorial.

Tutorial SC - New brake caliper mount bgm Vespa PX

 

Our professional brake caliper mount from bgm PRO Made in Italy: Allows the assembly of the radially mounted BGM PRO 4-piston brake caliper, which enables braking values ​​at motorbike level with fine dosing.

VESPA OR LML?
The brake caliper mount is available for Vespa or LML. The difference between the two types lies in the different dimensions of the speedometer drive. The selection of the right adapter therefore depends on the existing/used brake drum (Piaggio or LML).
Examples:

  • A Vespa PX (1985 model) that was subsequently converted to disc brakes with a Grimeca retrofit kit requires the PX adapter.
  • A Vespa PX (1985 model) that was subsequently converted to disc brakes with an LML fork requires the LML adapter.
  • A Vespa PX Disc (1998 model) requires the adapter type Vespa PX.

THEREFORE ONE LED SKEYSNWERFER AT THE VESPA? 

For most scooters, the limit with conventional Bilux light bulbs is a headlight bulb with 45/45 W. The ignitions, which are usually 80 W to a maximum of 120 W, do not provide any more. The luminosity is measured in lumens below 400. The LED headlight has a luminosity that is three times as high (1300 lumens). The power consumption is only 20 W. This corresponds to the light output of a conventional 100 watt spotlight. With a given alternator / power supply, a considerably better illumination can be achieved. In addition, there is more capacity for other consumers.

7 On the Road - Vespa bgm Platónika project by Scooter Center

As we would say in Colombia: “I'm in my salsa * " (it means that I am fully in my element).  I received Platónika with 18 km and exactly 15 days later, she had a thousand km more.

Completely excited because spring is already there colors I started to drive. And even put together a Motonostra accessory set for touring:

Windshield

MN2514BB

Foldable rear rack

TW3223B

But with this German weather you never know! And sure enough, a week later it starts snowing ... that shouldn't stop me, so I'll protect myself from the harsh cold and keep going.

Pictures and videos come and go, but I still think I'm missing something. The reason I fell in love with this scene: Indeed, their Vespisti.

No meetings in sight, "then I'll go with my colleagues" I thought, but who could go with me? in the marketing office where i'm sitting i only have the two of them Lambretistas found…

And now ... why not?

 

Did you miss any details of Platónika's story? You can find the full story here.

Vespa sport shock absorbers

bgm PRO SPORT Shock absorber set | bgm7741BKTS

Based on the competition chassis, but without a separate expansion tank and a fixed damping rate. Ideal for everyday sporting use, even with powerful engines.
Very harmonious basic set-up with an optimal balance between sportiness and suitability for everyday use. Compared to the Competition chassis, it is infinitely adjustable in height. This means that the height of the vehicle can be adjusted on both axles. In this way, the front can be lowered or the rear can be raised without having to change the pre-load, which is so important for the negative spring deflection. The front shock absorber can be continuously adjusted between a height of 240mm and 220mm.

  • stepless adjustment of the spring preload
  • sporty, harmonious damping technology
  • individually height adjustable (20mm)

 

Vespa tire set

The Complete set of tires -bgm Sport black matt tubeless bgm tire and bgm Vespa aluminum rim | bgm35010SLKB 

BGM Pro Sport tires (3.50-10) fully assembled on aluminum sport rim BGM Pro tubeless (2.10-10)
Ready-to-install tire set consisting of the first-class BGM Pro sports tire with a speed index S (approved up to 180km / h) and a load index of 59 (243kg per tire) as well as the exclusive BGM Pro light alloy wheel *.

TIRE
The specially coordinated material mix with a high silica compound ensures excellent grip in dry and wet conditions. The extremely stable carcass ensures perfect straight-line stability and excellent line accuracy when cornering quickly. Usually tires are simply pressed into shape from a layer of rubber. The bgm tires are significantly more complex to produce and consist of several layers in order to create the perfect tire that meets the highest requirements and has the highest speed rating on the market.

RIMS
The solid aluminum rim from BGM PRO made by FA.Italia saves around 600 grams compared to an original PX steel rim. In addition, there is a weight saving of around 370 grams due to the hose that is no longer required. The unsprung mass is thus reduced by almost one kilogram per axle. The responsiveness of the chassis improves noticeably.

SAFETY
With a double so-called "hump" in the rim bed, the tire is always safely guided in the rim. Similar to the latest runflat technology in the automotive sector, the air can slowly escape if a foreign object (nail or similar) is inserted without the tire slipping into the rim well. The vehicle comes to a controlled stop. The rim has recesses between the screw-on points. The cooling of the brake is improved.

 

Vespa 4 piston brake caliper

Brake caliper and brake carrier bgm Touring | Bgm2506BK & bgm2507LBL

Solid 4 piston Vespa brake caliper with radial attachment.
Two-part CNC milled housing made of high-strength aluminum, anodized.

With 4x25mm pistons, the caliper has 40% more piston area than a conventional two-piston caliper with 30mm pistons. The hydraulic transmission ratio is greatly improved and the braking force (with the same lever force) increased. Another advantage of the 4 piston technology is the symmetrical loading of the pads, which means that they are always fully in contact. A pad change is done quickly and easily with a stud bolt. A big advantage in racing. Central connection of the brake line.

Adjust cylinder overcurrent channels in the motor to optimize performance

Vespa Tuning: Before the complete assembly of the engine can be done, all the work that generates chips has to be done. Only then can the housing be cleaned.

In the next step, this includes the overcurrent channels of the cylinder in the motor.
The BGM177 is designed in such a way that the cylinder also works perfectly on the original overflow channels.
In our project, however, we use the opportunity to adapt the housing directly. Better filling of the cylinder always means one higher possible torque.

The easiest way to transfer the contour of the overcurrent ducts to the motor housing is to place the appropriate cylinder base seal on the housing and thus transfer the contour to the housing.

The sealing surface is best marked with a foil pen. Then, with the aid of the cylinder base gasket, the Contour of the overcurrent channels marked.

The contour in the motor housing is then adapted with a milling cutter. It is not necessary to mill the channel exactly as deep as in the original motor housing.

The BGM 177 cylinder is designed from the basic construction in such a way that the piston offers a sufficient cross-section.
The generated surface of the adapted channel can be milled and rough. No further polishing is necessary. As long as there are no rough corners and edges, a slightly roughened surface is perfect.

After the channels have been milled and the housing cleaned again, assembly continues ...

How do I mount the tires on a Vespa / Lambretta?

Using our example bgm Classic tires we show the correct assembly of the tire (split rim).

1. Reduce friction 

The inner tube is subject to flexing when the tire rolls and therefore it makes sense to cause friction inside talc to reduce.
The white powder reduces the friction between the tube and the tire and thus the wear and tear of the tube.

A small amount of talc is distributed inside the tire and the tube is filled with air just enough so that it does not expand and is also dusted with a little talc.

2. Check the direction of travel

Before installing the tube, please first check whether the tire has a direction of rotation specified by the manufacturer.
This notice is with ours bgm Classic tires in the form of an arrow on a tire flank and indicates the direction of rotation of the tire when driving.
The tube is then inserted to match the direction of rotation of the tire, so that the valve, typical for Vespa, points to the left-hand side in the direction of travel.

3. Assembly

To mount the tire on the rim, the so-called Montagepaste a real help. This means that the tire can be pushed very far onto the rim. This makes screwing the two-part rim much easier.

First, the valve is inserted through the wide half of the rim and then pushed into the tire.
The narrow rim half also has an opening through which the valve is accessible. When inserting it into the tire, make sure that the clearance for the valve is congruent with that in the wide half of the rim.

Our bgm Stainless steel rims have replaceable bolts. During assembly, it is important to ensure that the head of the screw is inserted into the square to prevent rotation.

The five nuts of the rim halves will be crosswise with 16 - 18Nm attached. When attaching, make sure that the hose is not trapped between the rim halves.
Then the Inflate tires to 2 bar and check that the tire and valve are correctly seated in the rim.

Our video and blog today is about measuring the inlet angle, also known as the inlet timing.
The inlet angle should move in a certain range which is given in degrees crankshaft. As a fixed point, the measurements always start from the top dead center, or TDC for short.
The inlet area is therefore divided into the values ​​“before TDC” and “after TDC”, since the inlet is opened before top dead center and closed after passing through top dead center.

For a Vespa engine with rotary valve control, the values ​​of approx. 100 ° before OT and 65 ° after OT have resulted for a good touring concept.
For very performance-oriented concepts that sometimes have to operate at a higher speed, the values ​​can also be significantly higher. 120 ° from OT and up to 75 ° after OT can be found here. The inlet angles must always be selected to match the desired concept. Here the principle applies in favor of a simple tunability of the carburetor and a homogeneous power development to make the inlet area as large as necessary and as small as possible in order to achieve the desired values.
The two-stroke heart of Platonika should be a powerful aggregate and therefore the inlet should be in the range from 100 ° BCE to 65 ° BCE.

In order to determine the angle of incidence exactly, some tools and materials are required.
• Motor housing
crankshaft
• cylinder and piston
• Bearing dummies

BGM PRO- 613912 (25x62x12mm)                                                       BGM PRO-NBI 253815 (25x38x15mm)

• Dial indicator with holder

Degree disc or similar measuring device

Bearing dummies

Since it is very likely that the inlet area in the motor housing will have to be machined in order to achieve the desired angle, the use of so-called bearing dummies is advisable.
With these dummies, the crankshaft can be removed from the engine housing for machining any number of times without the bearing seats of the crankshaft or engine housing being stressed each time and already experiencing wear before commissioning.

The bearing dummies are available for every size of the bearings commonly used in the Vespa and Lambretta range.
The first step is to insert the bearing dummies into the motor housing. Then the crankshaft is simply inserted into the bearing dummies and the motor housing is screwed into the stator housing using the stud bolts.

Trade Shows

In order to determine the TDC, the cylinder and the piston are required. The piston is pushed into the cylinder without rings so that the work goes smoothly. The dial gauge is screwed onto the cylinder with the holder and the TDC of the crankshaft can be determined.
The alternator side of the crankshaft is provided with a degree disk or a digital protractor. A wide variety of options are available here. The easiest to use are digital measuring tools such as the Buzz Wangle Indicator that does not require a reference point to the motor housing.
If the crankshaft is in TDC, the degree disc, whether digital or analog, is set to "0" and then the crankshaft is rotated to start and close the inlet. The value read on the gauge then shows when the inlet is open or closed.

Increase the admission time

In order to bring the inlet to the desired level, the crankshaft is moved to the desired value and the position of the crank web is marked on the engine housing.
If this has happened for the value before and after TDC, the engine housing can be opened again and, thanks to the position dummies, the crankshaft can easily be removed again.
Care should be taken when working in the inlet area. The surfaces that seal the rotary valve must not be less than approx. 1mm overlap with the crankshaft on the sides.

Once the inlet has been machined to match the markings set and the crankcase has been cleaned of machining residues, the crankshaft is reinserted for inspection.
The measuring device is then used to check once again whether the desired control angle has been achieved or whether reworking is necessary.

How do I measure the pinch edge on the cylinder head?

In our second tutorial we describe how to do one bgm177 cylinder its general Pinch edge is measured and adjusted. The process can of course be used for all other cylinders, but the dimensions can vary greatly depending on the manufacturer or the desired application of the cylinder and differ from our dimensions in the video.

For the heart of Platónika we have that bgm177 cylinder first mounted dry.
This means that the piston is initially mounted without piston rings and only with the upper bearing of the crankshaft. So if the cylinder has to be assembled several times in order to set the correct squeeze dimension, the threading of the piston rings is bypassed until the final assembly.

The bgm177 cylinder lie several and with 0,2; 0,4 and 0,6mm different thicknesses Seals for the cylinder base.

The cylinder is mounted without a seal for the cylinder base. We use to map the squeeze dimension soft solder with a diameter of 2mm.

The length of the piece of solder should correspond to the diameter of the hole. A little excess length doesn't do any harm to position the solder appropriately with adhesive tape on the piston, parallel to the piston pin.

The cylinder head is assembled and fastened together with the gasket. By turning the crankshaft, the piston is turned once above TDC = top dead center. There the solder is squeezed together between the piston crown and the squeeze surface of the cylinder head to the squeeze dimension and thus forms the current crush dimension .
After the cylinder head has been dismantled again, the pinched solder can be easily removed at the ends measured with the vernier caliper become. In our example this results in a dimension of 0,62mm.
The Instructions from ours bgm177 cylinder gives us a recommendation Crush dimension of 1mm.

How do I change the crush dimension?

In order to get from 0,62mm to 1mm with the existing squeeze dimension, a cylinder base gasket of 0,4mm must be added; in order to arrive at the desired dimension of 1mm purely mathematically.

How are stud bolts installed on a Vespa?

As part of our Platonika project, which we are putting on the wheels together with Maryzabel, we are also preparing many important assembly steps in videos as tutorials.
Our first tutorial shows the important differences between the different types of studs and the correct assembly.
Common questions such as

  • "Which side is screwed into the motor housing?" or
  • “Will the stud bolt be glued in?”

will be in this Vespa tutorial answered.

In the Vespa range, the threads of the original stud bolts have a "thick" and a "thin" side.
The thread is shorter on the thin side and longer on the thick side.

The side with the thicker thread is screwed into the motor housing and clamps there automatically, provided the motor housing is intact. The stud bolt is thus secured against self-loosening. The free length that remains above the engine housing is determined by the cylinder and cylinder head.

Different variations

In addition to the different lengths of the thread, there are other features to distinguish them.
Here are the most common:

- Rounded end or paragraph

If one of the ends is rounded or clearly set off by a stud bolt and the other end is flat, the rounded side points towards the cylinder head and the side with the flat end is screwed into the engine housing. Stud bolts with a shoulder also make it easier to assemble the washers and nuts in the cylinder head later.

Stud set -M7 x 140mm

-Marking on the shaft 

On one side of the stud bolt, a marking in the form of a ring is attached below the thread. The marked side points towards the cylinder head and the side without a mark is screwed into the engine housing.

Studs -M8 x 160mm

-Blow or point marking on the face 

If an end face of the stud bolt is marked, which can be a point, a star or a kind of cross, this is the free side of the stud bolt and the opposite end is screwed into the housing.

Stud -M7 x 59mm- 22-17-20mm

- solid screw lock

Stud bolts with screw locking applied by the manufacturer are easy to recognize by the material. The side with the screw locking device, which is clearly visible in the color blue, green or red, is screwed into the housing. The free side is blank, without any application of security.

Studs -M8 x 165mm

-Special cases

are, for example, stud bolts that have a clearly marked side but whose installation side to the motor housing does not have a thicker thread. These stud bolts are to be mounted with screw locking.

Stud set -M7 x 158mm

Installation of the stud bolts on Vespa engines

In order to mount the stud bolts securely, we offer this simple but ingenious one Stud mounting set on. As a result, the stud bolt is securely fixed when it is screwed in and cannot simply twist, as is often the case with two locked nuts.

It would not have been easy for me to pick the best products, but luckily the technical department of the Scooter Centers actively supported here and created a never-ending list in painstaking detailed work in just a few hours.

The whole thing would have cost me months, because this is not just about him Cylinder -BGM PRO 177 cc, its general BGM Pro SportTouring bench or the Shock absorber -BGM PRO SC F1 SPORTbut really ALL parts, from the washer to the Chassis complete LML Star. Thanks to the wish list function of the Online Shops you can now see all parts that are built into the Platónika:
