Been to long since I adjusted the chain on my 2000 KTM 400 EXC. When I tried it wouldn’t move. I read somewhere that there was a kit you can buy that included a tap, drill bit and new bolts. I don’t remember where I read it. I’d like to have the kit before I go any further so if/when it does strip out, I can take care of it right away without any down time. Gotta ride you know. If anyone knows where I can get this kit, help.
