In general, my bike runs very well, however, I have has three episodes of it running like ass after sitting in traffic or going along slowly in traffic. So the bike will be running perfectly and then all of the sudden when I accelerate, the bike sputters, backfires and has a total lack of power and acceleration. It self resolves after I get onto an open stretch and just start rolling on the throttle and powering up the RPM range for a bit. It seems to clear up after a good flogging. I am guessing the plugs might be fouling?
The bike has sat in storage for several years so I am going to replace the plugs and wires for good measure.
Ideas?
