Exhaust BGM PRO Big Box Touring – “BBT V2”

The BBT V2 is a further development of the well-known Big Box Touring exhaust system. During the revision, we attached great importance to depicting the widest possible spectrum of usable engine concepts.

Our prototype was driven more than 3000km to ensure that the final product delivers what it promises.

It was driven on an original (unprocessed) Rally200 Femsatronic block with standard shaft and Malossi 210 Sport as it comes out of the box.

In our tests, the engine developed just over 17 hp. Due to the higher performance and the higher torque, a straight-toothed 23/63 BGM primary is installed (3% longer than standard). The base plate of the Femsatronic was reworked to a long hole in order to be able to adjust the pre-ignition from a fixed 24° before TDC to 18° before TDC. The squish edge as specified by Malossi with 0.9mm and the air filter without drilling / processing.

Sitting upright on the Autobahn, the scooter runs at a reproducible speed of 120 km/h (according to GPS), corresponding to 7000 rpm with an additional 16 hp on the wheel.

In this graph we show the BBT2 (blue) compared to a Polini Box (red), measured in third gear:

The manifold, the contour of the exhaust shells, the damper chamber and the selectable diameter of the tailpipe are the changes made in detail.

The manifold itself has been modified in the course and to increase performance and the new exhaust shells have been optimized for more ground clearance.

In the damper chamber we have added components to achieve further turning and an increase in torque. The tailpipe can be adapted to the displacement and the speed of the respective engine by removing a plug-in part.

The tailpipe with plug-in part (d=18mm) is suitable for touring-oriented engines such as e.g Malossi Sports, Polini 210/211 and Quattrini 232

After removing the plug-in part, the new BBT has a tailpipe diameter of 20mm Quattrini 244-252 and Malossi MHR very good and also offers significantly more power and speed without thermally influencing the engines too much.

In summary, the BBT V2 achieves more across the entire speed range than the previous version on current engine concepts.

In addition to my everyday driving device, Maryzabel's Platonika also had to be used for experiments.

You can read about the exact equipment of the Platonika with our bgm177 cylinder here in the blog link to blog:

Here is the comparison on the engine of the Platonika:

My daily ride, equipped with a Malossi Sport 210, Set primary incl. clutch, Clutch pinion
+ primary + repkit and via a membrane with a YSN30 carburettor link to blog: carburetor YSN30 https://blog.scooter-center.com/fast-30-mm/ )
ventilated, this engine represents a drive machine of the current generation.

Changed course - the manifold runs closer to the exhaust body and is additionally supported with a strut

Depending on the engine concept, the plug-in part can be pulled out

The BBTV2 is available now for the PX80, PX125, PX150 and the like, as well as the PX200 and Rally200: https://www.scooter-center.com/de/search?sSearch=bbt2

BGM BigBox Touring for Vespa T5

The bgm BigBox Vespa T5 is designed as a replacement for the original sensationally good exhaust system of the Vespa PX special model T5. The T5 engine designed by Morini has some peculiarities due to the adapted powerful 125cc motorcycle cylinder.

The T5 engine reacts very strongly to the exchange of the exhaust system. The BGM BigBox for the T5 is based on the standard exhaust in order to keep the torque in the lower and middle speed range at a similarly high level as the standard exhaust. Depending on the setup, it can turn out a little further.

Nice to see at our customer Nino in Portugal, Original T5 with the bgm BigBox. Seems to be fun:

Vespa T5 152cc Polini with BigBox

Conclusion

Nice to see in the diagrams: ours bgm BigBox harmonizes with the original engine as well as with Polini 152 or Malossi 172 tuning cylinders. On revised engines, the larger volume of the BigBox Touring results in a significantly better torque and power curve than with the original exhaust.

Vespa rear brake arm convert to T5 adjustable for Vespa PX, Rally, Sprint,

Largeframe, News, Vespa

Conversion to adjustable brake cable Vespa PX, Rally, Sprint,

The brake pad wear of the front brake of the PX series up to 1998 and the PK-XL can be easily adjusted without tools using the well-known knurled screw on the brake cable.

On the Vespa PX125T5, this luxury can even be found on the rear brake.
With this model, Piaggio has already seen that the fiddly-to-use adjusting screw in hard-to-reach places is no longer state-of-the-art.

We leave the no longer available Piaggio original part of the T5 in excellent quality reproduce.

Greater braking force with the same pedal force

The brake arm fits almost all Vespa Largeframe Models and is one meaningful improvement especially for all PX before 1984, as well as rally, sprint and co, because the brake arm is longer and a greater braking force is generated with the same pedal force.

Our practical conversion kit

With the Set for retrofitting every PX can be brought up to the state-of-the-art.

The solution for perfectionists with a T5 brake cable

In order to carry out the conversion, a slot must be made in the cable guide of the brake pedal. The T5 brake cable has a cast nipple at each end and can therefore no longer be threaded through the bare hole in the cable guide on the pedal. In addition, the M8 set screw on the PX engine blocks must be removed and drilled to the size of the brake cable abutment.

The simple adapter solution

Those who shy away from the effort described above can easily fall back on the variant with our adapter for the pulling thread:

If the brake cable is not to be completely replaced, we also offer a fast one Adapter solution

Conversion for Largeframe Our Oldies

For the Vespa Largeframe Models with an external brake pedal, such as Vespa Rally, Sprint, VNA, VNB, etc., can also be converted either with the adapter or with one loose brake cablethat has one end with the matching thread.

The simple installation using a Vespa PX

Here we briefly present the conversion using the example of a Vespa PX.

In order to be able to replace the brake arm, it is necessary to remove the brake cam.
In order to gain access to the cam, the rear wheel and the brake drum are dismantled.

cap and Sapwood remove

Dismantle the rear wheel

and then the brake drum remove.
ohne impact wrench is the Holding tool for Vespa and Lambretta brake drums a real help.

If the brake drum is removed, the brake shoes are freely accessible. Here it is worth taking a look at the position of the brake cam.
If the cam is almost 45 ° inclined to the brake shoes with the brake pedal unloaded, as shown here, this is an indication that the Brake shoes are soon worn out.

In order to be able to pull the brake cam a bit out of the guide, it is necessary to Brake shoes to remove. the Retaining rings can be removed quite easily.
However, care should be taken to secure the little nasty things against jumping away.

With a wider one screwdriver the jaws can be spread apart and removed one at a time. Shouldn't the brake shoes
are replaced, it makes sense to mark the installation position on one of the brake shoes. As can be seen in the picture above based on the abrasion,
the approaching brake shoe is subject to a different wear pattern than the decelerating brake shoe. Therefore, it makes sense to remove the brake shoes when reassembling
to put them back in their accustomed place.

After unhooking the spring for the brake arm is the Safety split pin accessible. Once the split pin has been removed, the Brake cam pulled out
become and gives the Feder and the brake arm free.

The brake cam is provided with a franking in which a Fat storage is introduced for long-term lubrication. Just fill up if necessary.

If the brake cam has the latest lubricant technology, the brake arm and the spring can be installed.

Do not forget the cotter pin before attaching the spring.

In this case, new brake shoes are used. To protect the guides from corrosion and to prevent the brake shoes from seizing up,
will be here copper paste applied.

With the main shaft as support, the brake shoes are placed in the guides.

The Mother the Lusso main shaft with SW24, for example, is fitted with a torque fastened by 110Nm.

Before cutting the old inner cable to length, check whether the Adjusting screw is on “0”.

The required pull length for the adapter can be determined based on the position of the brake arm. The pull should be right right up to the end of the arm
are sufficient. the Cable shears ensures a clean and safe cut without the cable fraying.

Push the adapter up to the end of the inner cable and secure it with the clamping screw. After the first test braking, check whether the end of the train
is still in the same position. If not, the clamping screw must be checked and retightened.

So that the adjusting nut on the adapter is easy to move at all times and does not corrode, a little copper paste can also be used here.

Mount the rear wheel again and the wild ride can go on.

New engine housing T5 from Pinasco

Largeframe, News, Vespa

Motor housing Vespa T5 from Pinasco

Just got us from Pinasco the news reaches us that the long-announced engine housings for the Vespa T5 should arrive next Thursday.

Pinasco engine housing for Vespa T5 here in the VespaScootershop order

The engine housings of the rare Vespa PX125T5 have always been few and far between. We are all the more pleased that something is happening again with the products for the T5.

Diaphragm and rotary valve engines for Vespa T5

Pinasco now offers two alternatives. Like the PX motor housings also, it will for the T5

a classic Rotary valve (Master) and article number: PN26482024
a motor housing with Membran (Slave) give. Item number: PN26482025

In terms of price, the T5 motor housings are slightly higher than the PX variant lie.

More technical details We can only give you this when we have received the first motor housings in the next few days. We keep you here in Scooter Center Blog up to date.

Build T5 engine

The easiest way to complete such an engine is to order the appropriate engine revision kit: Engine revision set Vespa 125T5

Information about a super suitable Exhaust you find here Vespa T5 exhaust

First pictures of the Pinasco T5 engine

Here are some pictures that Pinasco made available to us.

The motor housings are expected to be delivered with all fixed stud bolts and suitable silent rubbers for the motor cross-member and shock absorber mount.

Pinasco engine housing for Vespa T5 here in the VespaScootershop order

Pinasco engine housing for Vespa

The Pinasco motor housings are very high quality replacement motor housings made of the finest die-cast aluminum. In addition to the very precise processing, they also offer many special features that are particularly interesting for tuners.
In addition to the significantly larger sealing surfaces on the cylinder base and carburetor inlet, Pinasco also offers the housing as a version with a diaphragm inlet. This suction technology, which has long been standard in the automatic sector, also offers large carburettors a good passage to breathe deeply. Further reinforcements in the cast, a larger crankshaft bearing and the great scope of delivery round off the superb overall picture of the Pinasco engine housing perfectly.

The housings are manufactured in two variants:
MASTER = ROTARY VALVE INLET (LIKE FROM THE PIAGGIO FACTORY)
SLAVE = DIAPHRAGM CONTROLLED

The engine internals and ignition components of all 125-200ccm models from 1982 onwards can be taken over. The components built from 1984 onwards are preferable due to the improved and more stable gearbox and the more powerful alternator. The motor of the COSA models is also well suited as a donor motor. Their engine block is outwardly different, but uses the same innards as the PX models from 1992 onwards.

Both versions have the same useful improvements:

MATERIAL
High quality die-cast aluminum with a fine surface
SEALING SURFACES
Very precisely milled sealing surfaces
STRONGER
Reinforcing ribs in the area of the main shaft bearing on the switch latch side and the shock absorber mount
SOLID
Significantly more material in the area of the cylinder base sealing surface and the carburetor inlet
OIL SEAL
The housings are made to accommodate a metal shaft seal (coupling side). Please always use the version for the 200cc versions with a brown sealing lip.
FIT
Two additional fitting bushes = crankshafts with an excessively long stroke can do without the centering edge of the Lima half. Dimensions of fitting bushes AØ = 9,95mm, IØ = 8,40mm, h = 13,80mm
RUBBER
The holes for the large silent rubbers are Ø = 44mm (original Piaggio Ø = 43mm).
The enclosed silent rubbers are stiffer and offer better guidance of the motor in the frame.
Piaggio silent rubbers also fit. Solutions with metal bushing or without pre-tensioning usually do not fit if they were manufactured for Piaggio engine housings (Jockey, PLC).
NUMBER
The motor housings do not have an embossed motor number or prefix
OIL HOLE
No drip hole for gear oil = the nonsensical drip hole that shows whether the inner shaft sealing ring is defective has been left out *.

* Our tip: run the sealed bearing and external shaft seal with the appropriate brake drum.

SPECIAL FEATURES ROTARY VALVE VERSION
- Extra large sealing surface over both engine halves, suitable for all intake manifolds
- Can be used as a 1: 1 replacement for an original motor housing
SPECIAL FEATURES OF THE MEMBRANE VERSION
- Central, full-surface membrane inlet
- Incl. Membrane intake, incl. Membrane in RD350 format (hole 58x48mm)
- Suction rubber can be rotated 360 °, connection width carburetor = Ø34mm
- Rubber suitable for Keihin PWK28, Mikuni TMX27 / 30, Dell'Orto PHBH28 / 30, VHS24-30
- No cast-in axis for oil pump control
- No hole for oil pump drive

The enclosed fitting bush for the auxiliary shaft must be inserted by yourself
If transmission components other than those of the PX models from 125cc are to be used, please check the auxiliary shaft axis for compatibility beforehand and change it if necessary.
Please insert all stud bolts with high-strength screw adhesive. The cylinder studs are not oversized on one side, as is the case with the original Piaggio. Therefore, glue in the supplied Pinasco cylinder studs here as well. We recommend cutting all threads and cleaning them with compressed air.
ASSEMBLY NOTE:
The crankshaft bearing NU205 on the alternator side is not seated flush in the engine housing.
It protrudes approx. 1mm towards the crankshaft.

DELIVERY

· ROTARY VALVE
- All studs
- Silent rubbers + washers for silent rubbers
- Housing seals
- Bushing for auxiliary shaft axis

· MEMBRANE
- as above, additionally included:
- Intake manifold including membrane, suction rubber, seal and small parts
