Cylinder kit - Stage6 R / T MkI 70ccm - ø12mm
The Stage6 R / T 70cc cylinder kit is an extremely powerful cylinder kit and compared to all other cylinder kits on the market, it stands out a lot. Among other things. fasten the cylinder with short studs at the bottom and not with long studs that go all the way through the cylinder and the top piece. This means there is ample opportunity to make the exhaust port wider, without making a hole for the studs.
The mounting of the exhaust flange has been changed so that it is fastened with three bolts instead of two. It is possible to buy loose flanges for the more well-known Racing exhausts and DIY (Do-It-Yourself) flanges.
The performance of the cylinder kit is absolutely at the high end and it is therefore on par with Hebo Manston, Malossi MHR and Polini Evolution. To achieve full effect of the kit, it is recommended to use i.a. larger carburetor as well as exhaust. A long-threaded spark plug must be used for this cylinder. The kit is delivered complete incl. gaskets, piston ring, etc. Note ø12mm cross pin. Crankshaft with rod85 connecting rod must be used.
In order to be able to mount the cylinder kit, it is necessary to mill the engine block up to 56.7 mm, to make room for the skirts.
