Here is the version named T6 RACING for MBK 51, we can also name it T4 racing because it actually has 4 intake transfers and a bar exhaust so in 2 parts!

And what a pleasure, it has been so long that we have all been waiting for a good cylinder with a bar exhaust, in aluminum and in 47mm diameter for our good old AV10 engines! This kit therefore has an aluminum cylinder, the finish is really much improved compared to what AIRSAL did at the time.

In addition this cylinder offers an excellent surprise! The intake diagrams are very well created, the transfers and their ducts are a superb base, and you can ask 187 ° to the exhaust diagram without having to touch up the admission! The exhaust is therefore a bar model, fabulous for preparers! The stock exhaust is small to preserve the torque and for the high engine to speak on any configuration even in small carburetor, once prepared:

this high engine can be a real monster, a large exhaust well prepared and a little stock intake really offer you outstanding performance. Even better! The delivered piston is in thin mono-segment 1mm thick, and of very good quality! The last surprise, let's face it, is the price! It is still very low!

The pack contains:

-Single-segment Ø47mm piston
-Segment steel Ø47mm by thickness 1mm
-Piston pin Ø13mm
-G piston clips

-Cylinder Ø47mm, bar exhaust, 4 intake transfers
-Reinforced cylinder head gasket

We recommend that you accompany this kit with at least : reinforced crankshaft (this kit comes out a lot of torque even original), carburations in 17mm PHBG with pipe, slats of valves 0.25mm or 0.30mm, large diameter cylinder head (the POLINI agree very well), cold racing candle, lightening of the variator or hardening of the spring, racing exhaust muffler adapted to torquey kits (DOPPLER ER1 for example) ... Attention, if you want to use a decompressor and not an electric circuit breaker to turn off the machine, you will need to re-drill the conduit into the cylinder.

As an option, we offer a STAGE 1 preparation, this preparation includes a selection of the best part from our stock, a marked improvement in the shape and exhaust diagram as well as a special touch-up of the cylinder skirt and the piston. for better scanning / filling according to our best tests. An improvement in the lubrication and cooling of the bar (cross type) is made in passing with a view to the regimes obtained after the preparation. This prep requires an additional period of 2 to 15 days depending on our availability! It requires tools and around 4 to 5 hours of work on this cylinder. The price is therefore accordingly.
