Okay, need some help here. I have a 2004 WR450F and changed the left side cover and upgraded to 2005 starting system, changing the one way clutch, torque limiter etc. My problem is I purchased a new Yamaha 5TJ-15560-01-00 assy and the problem I have now is a really bad noise when using the electric starter. It will start the machine once in a while but the torque limiter will slip and not start the machine. Is there a way to tighten up the torque limiter? I am afraid to take this thing apart. And yes I did ask Yamaha for warranty and no luck. I guess they think there parts are all perfect. I also just fixed the right side of my 04 machine by upgrading the inner case off a YFZ450, and replaced the kicker boss from a 2005 to my kicker, and upgraded the kicker assy, due to Yamaha had problems with a smaller kick shaft and when I tried to kick start my machine, the shaft broke in half. But I need your guys help on this TORQUE limiter. Thank you.
