I've been working on cleaning the throttle bodies and checking sync. I removed the throttle bodies and looking inside they were really dirty. So I used some good carb cleaner spray and it really cleaned them up. The bike really runs nice and smooth now . The other thing that had been bugging me was there was no slack in the throttle cable, at the throttle, and I believe the manual shows about 1mm of required slack at the cable adjuster, on the Left throttle body. When I looked closely at the throttle cable, on the left throttle body, as it seated in the adjuster I could see it wasn't fully seated. I followed the cable up about 5" and it was ty-wrapped to the frame. I couldn't move the cable to get some slack in it so I cut this ty-wrap and the cable slid fully back into the adjuster. The ty-wrap was overly tight, so the cable had no free play. It now has the 1mm of slack at the adjuster and the throttle now has a little bit of slack. This also explains why occasionally the throttle seemed like it wouldn't completely idle down and needed to be blipped a couple times. Beware of those ty-wraps.
