I am buying a bike (2000 KTM 200 EXC), and the seller said the bike was repaired (The 5th and 6th gear had disappeared), and he wasn't sure exactly what the shop worker had done to fix this. Is this a common problem on the KTM 200 EXC's? Has anyone experianced any lose on gears? If so, has it been repaired, and what is the outcome? Once it is repaired, how long will it last? I have no clue as the present owner doesn't know exactly what was done to the repair, and says he had ridden the bike a few times after this and the bike ran fine. Any replies are greatly appreciated.
