Hi Chris, ive only ever had my bike on a dyno once and that was at an open day at a bikeshop and all they did was measure the power - no mods. If the dyno operator knows his stuff then the least he will be able to do is offer advice. If its stuff like raising the needles to make the mixture richer mid-range then i would have thought they should have the washers/shims to go in the carbs.

It might be worth giving Graham a ring to see what he thinks. I got a GF jet kit to go with my GF downpipes and its always been faultless through the revrange. top end is still a bit wobbly on the dyno graph but ive not been anywhere yet to find out if it can be improved.

i remember looking at putting a stubby can on my NC29, and the more i looked into it the more i realised it looked gash

+1 ^^^^
i love the sound of my bike with no end can on... but it LOOKS weird.

Chris, the +4 advancer does exactly what it says, I fitted one on my ZX7R and wow what a difference smoothed out the midrange power with no flat spots, dead easy to fit takes about 5 mins with the fairing panel off to start, all you are doing is replacing the ignition plate, undo one and replace with the other, simple.. I got mine from Facory Pro, I will be looking for one soon for my 23 so if i find one i will let you know mate ok :D :D :D
