Howdy hey again,
Anyway, I've settled on using the 2.50hp engine I have (circa 1968) for a board-track racer inspired bike (to be run as a really fun moped!). That being said, I can't seem to find any real performance parts for either the 2.5's or 3.0hp powerplants.
My goal is to not produce mondo HP numbers, but build something that is virtually bulletproof for a second board-track racer I plan on building (one for gentle cruising, & one for a different kind of fun :smile: ). I plan on going with a forged connecting rod, forged piston, better bearings, & installing much stiffer valve springs (including lapping them into their seats). And yes, the flywheel will be replaced with a proper performance unit (if one is available for these smaller engines to prevent a kaboom. Both units have cast iron bore liners & very, very low hours.
My question is, would a 2.50hp or 3.0hp engine with a stock crank (I'm not sure where to find performance cranks) hold up to extreme revs (6000+)?
I've been bitten by the B&S performance bug. A friend of mine was kind enough to lend me his Animal powered minibike, and it is a legitimate monster. Way more fun than I should have had on 6'' wheels. :thumbsup:
Thanks in advance!
