It's going to take a little more info to get an answer here, what has been done to the bike as far as tune up's and modifications. Obviously it is carbed and not FI so it could be a fuel problem too like water or sediment.

Almost sounds like the same problem the 08's have been expieriencing with the cracked fuel pumps causing them to lose preasure at low rpm.Im sure Glider will have an answer for you shortly.

See that, he's already got you covered..

I may have missunderstood this, but you have an '02 with only 2500 miles on it? Where has it been? How much riding has the bike had in the last month. Has it been sitting for awhile?

TQ

Great that you are getting into "the life". But the problem with a bike that has sat for long periods of time is that condensation (water) and sediment will settle out in the fuel system. This is made worse if there is high humidity with large temperature fluctuation dipping below the dew point.

So, the problems that you describe could be symptoms of this situation. I would suggest that you drain the fuel tank and the float bowl of the carb. Catch the gas from the float bowl in a clear glass jar so you can examine it. Once drained, put some "dry gas" in the tank and "swish it around". If you can, this is better accomplished with the tank removed from the bike. Refill the tank with new, clean, high octane (93 or better) gas.

Next, take the four screws out of the float bowl (I am assuming a Keihin CV carb) and gently lower the bowl to see how must "stuff" is in it. Clean it out carefully. See here:

Button it all back up, and see how it goes. Let us know, because if this is not it, then we go on to more problem-solving!!
