Clutch Spring!

Recommended Posts

Im going to put a tb 88cc race head kit on my 70. wondering how much of a difference it would be to leave the stock clutch spring or upgrade?

I've had absolutely zero problems with the stock clutch on my 70 motor set up with a standard TB 88cc kit. I also run the 50 primary gearing but I'm not sure how that would affect the longevity of a stock clutch. The 70 clutch has more flyweights than the 50 but otherwise is identical.
