And whats the max boost it can put out without hurting the motor? And when using a manual boost controller is there a way to know how much you are turning it up?
I'm looking to buy a 2003 Yamaha Bear Tracker 250 4 stroke. The seller said the motor has a new top end, good compression and good spark, but for it to run it needs the timing set. Does anyone know if that is a hard job?
