I have a 99 250 Exc. I'm planning on tearing the top end down to re-ring it and possibly put a piston in if need be.I have two questions. 1 About how long on average do KTMs get before they need rebuilt. I know it depends on use, conditions, etc. I maintain the bike very well but I do ride it hard when I ride.
And secondly has anyone tried a big bore kit or do they even make such a thing for the KTM.
Thanks,
