who said it needs a bore kit?firstly why does he/she think so ?does the bike have good resistance to the kickstart lever when you push it down or does it move very easily does it make any horrible grinding noises?if you put a finger or thumb over the spark plug hole with the spark plug removed does it blow you finger out of the way if someone kicks the engine over?there are alot of reasons why a bike wont run so please provide some clues for us to help you out.
