Last year I had to do a full motor teardown due to getting sand in my motor. While putting it back together i noticed that the teeth on the back side of the clutch basket did not fully engage the primary drive gear coming off of the crank. Does anyone have an 06 450 that can verify how much engagement there is supposed to be? I looked on my friends 08 and his teeth fully engage with eachother. Question 2 Once I completed this project and got the bike running i couldn't find neutral while it was running. Is this due to the basket being grooved as shown in the pictures? A friend said that he had a similar problem due to tighting the nut that holds the inner hub onto the transmission shaft to tight, could this cause a similar problem? Also what are your opinions on filing the clutch basket fingers ever so slightly to get rid of the grooves? The bike makes a hellacious growling sound while running, similar to the sound it used to make when the clutch was pulled in.
