I blew up my motor (busted cases, broken connecting rod) this past weekend in a race and after taking it apart I found that my cam chain tensioner was compressed in and stuck and not working like it should with the springed tension. ive decided that this must have been what caused my motor to blow. I think my tensioner was a few years old though, so I guess it finally gave out?
after doing some reading and searching on here, I seen where some people recommend using a manual cam chain tensioner because the stock spring loaded tensioner could possibly fail without warning (like mine did?). and a manual tensioner is basically a threaded stud with a lock nut, so it will never fail. but the only thing that makes me weary of it is you never really know how much tension is on it while your riding and stuff, and if its too loose or too tight?
so what would be better, a oem tensioner and replace it once a year (cheap insurance), or manual tensioner and take more time and maintaince to check it?
