Some times my bike decides to down shift by itself any idea. And some times ill be going 5th gear wide open and it feels like some one just pulled the clutch in the whole way. The bike does not feel as if the clutch is slipping as it wheelies with out a problem.

The feeling like the clutch was pulled in could be because it shifted into neutral.

Are you sure you are not accidentally tapping the gear shift? I have that problem a lot, when I go to stand up on the pegs I often accidentally tap the gear shift.

If it is doing it all on its own then it is a good indication that the transmission needs some work.

I would recommend changing the oil and examining the oil that comes out carefully. There should be a lot of silver color to the oil, which comes from the clutch. But if there are any chunks of metal that comes out with the oil then something is really wrong in the gear case.

It is possible that something in the gear selector mechanism has gotten bent or otherwise messed up.

I created a thread just like this, and I was told I could have bent shifter forks. It can happen when you don't use the clutch when you're shifting.

well the oil does not have any metal chunks or shavings. I always use my clutch. It might be me, i never used to where boots till now maybe im just not clicking it into gear all the way.

I bet it is the boots.

Seriously.

Your boots probably have metal tips and have very stiff toes. When you were riding in tennis shoes the tip f your shoe was probably a lot closer to the tip of your toe and your toe would feel the gear shift lever.

With the boots on you can hit the shift lever and never feel it.

An option you might want to consider would be to rotate the shift lever down a notch to get it a little farther away from your toe. Either that or learn to ride with your toes up a little higher or with you foot a bit farther back on the peg.

good point, but he said he would be in a high gear, like 5th and have a false neutral. Saying that, you would shift into 4. Although that could be a possibility if you were in 1 gear.
