Default Re: Vc625 connecting rod

Seems the right thing to do with a high rpm engine is:

1. Cam
2. Rev kit
3. Bigger carb
4. Billet rod
5. Billet flywheel
6. Belt driven alternator

This applies to any of the small engines. Since these engines aren't designed to run high rpm, you have to address all the weak points. I agree Ray, the magnets on the flywheel become shrapnel if it grenades at high rpm. Makes me nervous. Been thinking the same thing for my Vanguard. Since the billet flywheels don't have magnets etc you have to install an alternator. Using an automotive alternator is the solution. That mod is one of the more complicated ones, which is why you don't see many people do it. So the flywheel upgrade idea usually gets sh**canned.
