I don't know if this would help. But check and see if the clutch that sits on the shift star, see if the top and bottom are sitting on the shift star pegs the same distance. I hope I'm not confusing.

Who modded the shift star? Did they grind too much off? Is the roller and spring reinstalled properly? Did you adjust the shift shaft correctly? Is the hook on the shift shaft too sloppy? If you want help, we need info. Edited March 22, 2011 by bansheesandrider Quote
kjh Posted March 23, 2011 Report Posted March 23, 2011 I put a modded shift star and a shift pro kit in my bike once and it had the same problem. Not sure if you have both but if you do its most likely the problem. I took out the shift star and left the shift pro kit and it shifts great. Quote
AKheathen Posted March 23, 2011 Report Posted March 23, 2011 the only way you are going to get your answer is by pulling the clutch cover off and checking things. the shift star, or detent roller may have come loose, and you are lucky, but if the detent holds the star good in between each hump, and the drum is properly retained by the plate, then you heve to dog into your tranny and will likely fond a worn/bent fork, or a problem with one of the gears. the fact that it did not lock into 2 gears at once sounds promising, though....
