What\'s wrong with my bike?

[Guest]

I have recently noticed my '99 Busa stumbles a little bit sometimes, mostly when I let off the gas. I was just coming back from lunch, had the tach around 4500 RPMs and let off the throttle a tiny bit and the bike surged for a few times. I gave it more gas and it stopped. I have noticed this about a week ago going home from work, it was not a bad then. It was so slight that I wasn't sure that I hadn't imagined it.

I'm afraid this is the first sign that the cam chain tensioner is going to fail on me. I have had the recall done on it, and just had it tuned up at the dealers about 3 weeks ago.

Any ideas?

Need a lot more info on the bike ex. Airbox Mod, Pipe, PCII, or maybe just bone stock...

Although I would recomend checking your fuel filters to make sure there not clogged first.

Bike is bone stock, also it was far enough along in the production run that it did not require the fuel mod. recall.

Check your TPS.

clogged filters, I'll bet $10. Have ya run any injector cleaner?

As a matter of fact, that was one of the first things I thought of when it started, so I added fuel injector cleaner about a week ago and it is still doing the same thing.

The thing that seems a little odd is the way it stumbles just as I let of the throttle.
