Power-wise, you won't even notice the difference between going .040 or .060 over. I recommend going as small oversize as you can, to leave more cylinder wall thickness. If you need more power, try shaving the head, porting, and a clutch kit. If you want to go overbore for power, get a true big-bore kit, like the 414 or 440 kits that are out there.

I am interested in getting a used 400 2 cycle scrammy and stripping it down for drag racing only and retire my kawasaki 650 prairie back to the farm bike... Does any one know any specialists on these 400 engines that sell performance enhancements or any good books for 2 cycle hi performance engine building , Thanks for your time, Jim @ jhmachineshop central indiana
