I have a 00 426. I read some of the posts on sliders eating the swingarm, so I decided to check mine out. I have a LITTLE bit of wear from the square pads on the underside of the slider, but nothing serious. What is the general opinion of the TM Designs chain buffer? They seem a little expensive, but $65 for a chain buffer is a lot cheaper than repairing/replacing the swingarm!!! I have heard they work good with a little automotive goop under them, but which kind of goop to use? Just a silicone sealant? Also, has anyone installed a ZipTy Racing neutral switch cover on their 00? I do all my riding on the trails, have never had problems with fouled plugs, or any problem for that matter with my bike. Is the neutral switch cover a worthwhile investment? I'm ready for the firestorm of replies that are probably comin my way!
