I have an airbox lid delete, stock carb. and its getting .070 over, the jug is in the shop (pm me if you have a stock or lower bore jug you wanna sell). I live in Cecil County, Maryland (if that helps)
Id say 250-260 but a plug chop will tell all.But id say the 250-260 range will be about right and be safe unless youre winter riding or have an aftermarket pipe.
Ive got a jug off a 98 blaster with a .010 fresh overbore 125+ shipping.
