Miss fire that clears at higher revs

That's good news although it doesn't make any sense to me as I would have thought a restricted air filter would cause more problems at higher revs than low.  Just wish I could find out what's causing mine to run crap now.

Thats what i thought .... but i think the whats hppening is the ecu is restricting fuel because there's not enough air hence when you slacken off there's not enough fuel , and the ecu must be struggling to juggle the fuel mix between low revs and high revs .

I replaced my airfilter last month.Noticed the tube extending into the filter. Drilled out the spot welds,  removed, shortened & refitted the tube. I think aftermarket filters have this tube but originals don't.

At low revs/throttle (the manual doesn't state what range) the ECU uses manifold pressure/throttle position to control the fueling at higher revs/throttle it uses throttle position/revs.

Ye i think what happens is the bike is only getting air from the bottom of the filter coz of the cube, so that bit of the filter gets dirty quick and then starts to starve the engine of air coz it cant pull it fast enough round the tube .
