Crankshaft, connecting rod assembly long race for MINARELLI AM6

Crankshaft, connecting rod assembly long race for MINARELLI AM6
Ideal for the increased torque, power, here you will find a long race crankshafts for engine minarelli am6 50cc. Remember, the crankshaft has long stroke engine displacement increase and they will approach the said motor "square" as the race 40mm diameter 40mm for example. They are not approved, they offer a clear increase in power and torque! They can be mounted on cylinders specially designed for a long run, but also on kits 70cc or 80cc standard with a base wedge to raise the high engine so that the piston does not hit the head ... A long race 42mm for example, with high standard engine is mounted with a wedge of 1.5mm. Originally, the race minarelli am6 engine crankshaft is 39mm. For example: -Kit Ø47,6mm Crankshaft race origin 39mm = real 69,40cc -Kit Ø47,6mm on 42mm stroke crankshaft = real 74,73cc -Kit Ø50mm on original 39mm stroke crankshaft = real 76,57cc -Kit crankshaft Ø50mm 42mm stroke = real 82,46cc originally, the rod of am6 engine crankshaft is 85mm long (unlike DERBI who 90mm). Some crankshaft long race also have a long rod 90mm for laying with high standard engine, so you have to rely even more thick wedge (surcharges rod length). On a race crankshaft 42mm with 90mm long rod for example, it takes a hold of a 6.5mm instead of 1.5mm!
