I bought an OEM crank on eBay a few years ago that had been modified to be a +7mm stroker. Didn't really have a use for it, so I sold it.

Art said to me last winter that he can go until +6mm on OEM crank and its still safe.

Dasa use kawi 133mm rod on the +10, but I dont know for the +16

Same for ADA on the +8 : http://www.adaracing.com/personal-watercraft/billet-cylinder-kit-yam-8mm/34-210890

Thanks for you help. +6mm is a bad size......need a AM legal engine with pistons the are easy available in germany. So i can stroke +4 and use 89mm CR 500 pistons or buy a billet +10mm crank and use 62t 84-86mm pistons. Think +10mm is the better way but much more expensive:-(((((

Thanks,Andy

Is anybody running 144mm honda rods on there 8-10mm strokers? I thought about it for the obvious advantages a longer rod gives, esp for stroker motors however i know two stroke motors thrive on case pressure for bottom with an 11mm base spacer it may be fairly extreme?

I work at moment on the 2.SXR based engine. First one were 90mm 74mm stroke/133mm rods. Now i work on a 85mm 78mm stroke version with CR rods. Engine is nearly complete but saison is ended :-(((((
