Interesting stuff Frank and sounds like you've done a good job!

I've got a general question. My bike has the same "hic-up" problem that you mentioned above. At between 4000 and 4500 (just the revs I like to hold each gear in - change up under normal conditions at 5k + ) it does seem to "hic-up". I would actually describe it more as a "chug" than a "hic-up" but I think we're talking about the same thing.

Why does this happen?

I have the injected model, rather than carbs. It never started happening until after I had the SIL exhausts fitted. I was thinking it might be something to do with the mapping not being quite right.

I was going to get it looked at next service, but mine seems to happen more than just occassionally. Probably 3 or 4 times in a 10 mile commute to work.

Other funny thing that's happened since the SILs were fitted. Fuel like used to come on at about 130-140miles. Now it doesn't come on until 150-160. I'm getting better economy with the aftermarket exhausts! I thougt this would be the other way around. Maybe everything is set too lean.........
