I'm thinking about getting a stroker crank for my mini-moto but I'm questioning how I should go about it. Would it be ok to run a crank with a 88cc cylinder and stock head for a while? Eventually I'm gonna get a bigger valved head, but I wanna know if it'll be safe to run the stock head till then.
FAB, SILVER.......help me out on this!

 

itll be fine with a stock head run the xr 70 carb and intake

 

Well I have a 18mm and a 20mm carb. and an intake for it. So I sure I could use that instead.

 

sorry to throw dirt at ya Z50NAT, but it WILL NOT be fine with a stock head. thats is waaay too much cylinder volume to squeeze into that tiny *** combustion chamber. it will detonate so bad that you will blow a hole right through that piston gauranteed.
