Hello TT Friends! I have a question about my '00 426. It runs like a scalded cat, beaucoup power off the throttle under load once I am rolling. The only thing I noticed is when the bike is sitting still and idling, if I try to wick the throttle suddenly,it bogs or even dies. If I rev the throttle a bit, then give it the gas,it takes it, no problem. I talked to a fellow racer at the local Yammie shop and he said that this was a common condition with 4 strokes above 300cc. Also when cruising down a hill with the throttle closed, the engine backfires a bit. Again, the bike runs very strong, cranks on the first or second kick, so I don't want to resort to drastic measures or do anything that might cause it to run worse. Anyone else experience this phenomenon? Thanks!
