how about the clamps on the rubber boots? are they secured properly? I hear if they're loose it can cause issues.

just a thought, have you checked the plug wires and coils? if you're getting weak spark to a cylinder or two, or more, think about replacing the wires and seeing how much that helps you. bear in mind the bike IS 18 years old, and by now could probably stand to have new plug wires put in.

Man that's good to hear and know. I have had a slight bog myself and figured it was because I was running it without an air box. I now have the air box and am in the middle of repairing some fairings for it. Can't wait to get everything together so that I will be running sound. I'm really curious to see what kind of performance I can get out of this thing once its all together (plus new plugs b/c I only cleaned the ones that came in it, and a new cct that I only barely need). I mean Ive been happy with it riding it how its been and I'm confident it is going to be significantly improved now. Happy new year everybody and I hope everyone's winter rebuilds are going well. Once I get everything together I will post some pics.
