anyone have any experience with their big bore kits or other products? I'm considering the 80cc kit for the xr70

They use really light high quality forgings for their pistons, Ross is one of their usual vendors I believe. Their cams have logical ramp designs so they maintain reliability, good stuff. Their pipes aren't real flashy but they work really well.
I bought my first Powroll parts about 30 years ago while I was trying to turn a 1970 CB100 into a flat tracker. Good designs from a group with about 40 years experience tweaking little Hondas is tough to beat. ;)

I've got their stroker kit in my DRZ125. It is outstanding. Turn around time is quick, the advice is good and the service excellent. I don't think I would buy anyone else's small bore four stoke equipment.

would you say the power gain with your stroker was as advertised, better, or worse?

I'd say it's double. They claim 70%. You have to get the carburetion right, to get the most out of it, but their claims are accurate in my opinion.

We also got a stroker crank from Powroll ( for my son's CRF150 ). What a HUGE increase in power. Good qualtiy workmanship, too. We put a big bore piston in his XR80 last year, got more power, but not as extreme of an increase as the stroker.
