So I finally replaced my friction plates after procrastinating for a few weeks, but to my surprise, all the friction plates were within spec, right in the middle of the range listed in the service manual. A few of them looked somewhat worn out, but as far as thickness goes, they were technically still good.
I won't be able to test out the bike until Saturday when I'm going to the track, but is it possible to have the clutch slipping with plates still in spec for thickness?? Keep in mind, I hadn't changed anything before, all was well for about one and a half seasons and the symptoms I got last time were exactly the same as early last year when I had to replace my plates because they were pretty worn out. I'm a bit concerned that this wasn't the problem maybe, and it will still slip when I get up to 4th-5th gear this weekend.
I did not measure the steel plates since I know last time they were in spec and it takes a lot to wear out steel plates, so I didn't even buy any new ones. There were a couple of them though that had some spots on them of blueish color. Not much, just a few spots ranging from around 5-10 mm. I hadn't seen that before on clutch plates. Is it possible that the surface finish changed and they're way too smooth now causing the clutch to slip a bit?
