Hey guys,
I just recently did a full race setup on one of my zumas polini evo 2 crank and cylinder, Malossi OR tranny, Yasuni 21 pipe and all. Well it ran good during break in but after about a week I pulled out of the driveway and it just started SHRIEKING. Like a load squeeling noise coming from the motor. The squeeling sounds so bad I havent started it since. There isnt anything binding in the tranny so I am afraid im going to have to split the case back open again and that it is prob a bad crank bearing. These are brand new BGM race bearings too. I did this install very carefully and have 2 other evo 2 setups that work great.
What do you guys think? Crank Bearing and if so..why would it go out like that?
Thanks a ton everyone,
