How much can a 250x be bored?

Well...060 oversize is 1.5mm larger than the standard bore of 74mm.....this gives you a bore size of 75.5mm
Using the formula to calculate displacement, you have an engine with a displacement of 257cc [stock is 246cc]
You can only go .080 oversize with the stock sleeve as far as I know.
Powroll, Four Stroke Tech, and Curtis Sparks offer good big bore kits for these engines, but will require a new cylinder sleeve.
