Hi everybody. I have a question about the yfz 450r 2014-2017.
What kind of crankshaft + cylinder and piston kit would you install in original engine. The oem crankshaft and cylinder+piston kit (made in yamaha) or the alternative one?
What brand of the parts are recommended?
What kind of bearings would you install??
How many hours the stock engine of yfz 450r 2014-2017 will work?
