Complete air-cooled engine delivered assembled and ready to ride! We have equipped this engine with POLINI crankcases, a reinforced long stroke crankshaft RRD - PREPARATION to increase the stroke, and therefore, the displacement!
*For installation on an AV7 high mount chassis, use this adapter!
For intake / carburetion: MALOSSI MHR VL18 valves with an RRD adaptation shim as well as an intake pipe tuned to this center distance to install a POLINI CP 24mm EVOLUTION carburettor!
For the ignition part, we install an MVT PREMIUM (analogue with a small internal rotor variation), we refuse the installation of a DIGITAL DIRECT, which is too aggressive on an air-cooled long-stroke engine . For the High engine, we chose the MALOSSI 45.5mm with POLINI RADIAL cylinder head with STAGE 2 engine preparation taking the diagrams to 132° for the intake and 193° for the exhaust, the compression ratio increased to 12.5 : 1 under safety squish of 0.9mm. You will need to install an MVT SC exhaust with this set!!
