bellracing2 Posted July 5, 2008 Report Posted July 5, 2008 While drag racing today I was having a hard time grabbing 4th gear while w.f.o. , but if I just trail ride it shifts great . Nuetral is easy to find all the time . all stock with a dynoport 2 into 1 pipe and timing + 4 ( which today I beat a t5 banshee everytime in 400 ft runs and beat a yfz450 9 out of 10 times ) :biggrin: but this trans issue is starting to bother me . what ya think it is ?

The shift drum could be worn, damaged or worn shift fork, damaged gears, shift mechanism out of adjustment. Could be minor or major. These are not the best shifting bikes anyway... I would try inspecting the shift mechanism first, and go from there... If you have a manual, it is explained, with good pictures and illustrations, at the end of chapter 5 (Engine Lower End) and chapter 6 (Clutch, etc.). I have only done it with the clutch assembly removed. If it can be done with the clutch installed, I would suspect it would be difficult to do, because the idler gear is in the way. The shift shaft has a plate on the end of it, with a window, and two spring ends in the window. The adjust bolt sits between the spring ends in the window. When the adjust bolt is turned, it moves the end of the shift shaft plate up and down. The shift shaft plate has another small plate with a hook on each end, and the hooks turn the shift drum using the pins on the shaft star. With the transmaission in any gear but neutral, look at the gap between the upper hook and pin and the lower hook and pin. Turn the adjust bolt until the dimensions between both pins and the hooks are equal (as close as you can by eye is fine). That is the best that I can explain it. The adjust bolt has a jam nut and a tabbed lock washer. Pulling the clutch assembly will be your best bet. HERE is a link that discusses a problem similar to yours, good luck. Quote
