Hello, i'm newbie here and I dont know much about bikes. So I want u to ask. I want to put cylinder polini alu 50cc and what crankshaft i should put ? Yamaha Tzr 2009 years. Full stock, but exhaust system handmade v6. Or maybe you have better suggestions what to put in my bike. Please comment, express your opinion.
If you are just changing the piston/barrel for another standard, although aluminium, 50cc one, the standard crank would be good enough, if it's in good condition. If you think you need to change the crank then go for a full circle race crank. They range in price but all do mostly the same job.
