possibly the throttle boddies being out of balance.... I would usualy attempt to do these myself.. as they were simple to do on the SV.... slightly more involved with this thing... plus I want them to do a few other things at the same time as well... and if after they are done the problem is still around.. Im in trouble.....
the other bloke who has simular problems had his bike dyno'd... its only putting out 70HP

I dont think mine is that bad.. but its getting there.... hopefully can get it fixed... and use ALL the rev range quickly again!
