I got the spring in today. The clutch seemed to have grease!? on it. I wiped it out with a paper towel and hit it a little with sandpaper. I also sanded the clutch pads a bit, to get rid of any residue on them.
I put the Malossi Multivar back in with the Ninja Sliders. It still just doesn't have the top end, but I think I just need to get a bit more power now, as it has it on a very slight decline, got up around 45 indicated. Still only 32-33 on the flats and slight uphills.
I've still got my air filter, so I can remove the airbox, but I've got to buy jets. Also, I don't really want to jet for the air filter and then buy an exhaust later, only to rejet.
