I've been getting mixed reviews for both.

I found the hot rod crank shaft 4143 it's a stroked crankshaft takes it to 379cc it say but have to use a vertex stroker piston 2616a I think it was. I know KTM uses vertex as stock.

I found the vertex piston for it comes in standard and .50 and 1.00 over bore options how far out from stock can I bore out before it's to far?
