08 RSV just lost 4th & 5th gear. I've seen the post about the 1st gen's having this problem when a pin falls out of the shift drum.
I was able to get into 4th by down shifting to 2nd and then immediately upshifting into 4th. When I try to go into 5th, it won't go. I do the same thing, I downshift from 4th down to 3rd and immediately upshift past 4th into 5th. I am able to downshift ok, I only have a problem upshifting into 4th and 5th. 1st, 2nd, & 3rd shift normally.
When the clutch is in and I put it in first, it does not try to lunge forward so I don't think it is the clutch. With the clutch cover off, I can see travel when I pull the clutch.
This is an 08 with only 16k on it. The previous owner did the clutch spring upgrade.
This is a picture with the clutch cover off:

I have the clutch out and have a video trying to run through the gears down and up while spinning the back tire.
Any ideas?
