Hey I have Vito's 4 degree fly wheel key and I was wondering if anyone out here has ever experienced any problems with these keys, I know over heating can be a problem but that is not one of mine. Idle probs, and throttle probs????????????????????????

 

I ran a couple of Blasters with these crank keys. Only problem I ever had was when one of the keys sheared, retarded the timing and had to be replaced. Other than that, the other blaster has had the key in for a couple of years with no problems.

 

I'm with shady, as long as the flywheel is tight enough and it doesnt shear the key then there shouldnt be any problems with it. Overheating usually isn't a problem until you get over 5 degrees and run lots of compression or do a lot of slow riding.
