I have a 1999 900SS that had been taken care of by my mechanic which has since passed away.
I dont trust the dealership mechanics & have a bit of a mechanical problem that I'm hoping I can fix myself, or at least have a clue as to what it may be before I take it in to a dealer.
Let me start by saying that I use my bike every single day.
Lately I have had a problem with hesitation during riding.
Basically, I start it up and start to ride. As long as I just ride smoothly without hard accelerations, I dont have a problem.
But as soon as I give it a good scream from a red light or so, it starts cutting in & out while riding as if it is not getting fuel.
Then....as soon as I hit the next light I have to continuosly rev thru the cycle of the light or it will just shut off.....
I've changed the sparks, oil...etc...with no change.
It also seems to happen when I make frequnt stops throughout the day where I turn the bike on & off frequently.

thanks for any advice I can get.

P.S. I'm not sure if this has anything to do with it, but one of my exhaust cans is a little loose. It may be sucking air. Could that affect the air-fuel mixture enough to cause my engine to hesitate?

The cutting out under full throttle could be down to the fuel filter being choked. Do you know when it was changed?? Should be done annually.
The exhaust can being loose could give rise to the odd back fire but shouldn't affect the the air fuel mixture to any degree.

thanks nelly....
Sounds like a good place to start....
Is the fuel filter something I can get at easily enough to replace myself?
