Might be a daft question but hopefully someone can answer this for me (as it kinda applies to cars too);
i'm away to build a relatively hi spec 2stroke motor to drop into my scooter as a bit of a fun project. The bore up kits i've seen only go as far as 70cc (mines a 50 as std) - ideally i'd like more though (i've heard of a 90 but am having difficulty locating who makes it) since theres no substitute for cc's;
Now, the questions i have is what are the limiting factors in boring up and how much would it cost to have a custom cylinder/cylinder head/rings constructed and who could do it?
Bear in mind the engine in question will be reviing to about 12000rpm...if its not going to be reliable going >70cc on a 50cc BE then someone tell me!
Appreciate any help! :D
