On my 83 kuatana 650 i did the car rebuild for the second time. The first time i don't think i did it correct. I also replaced all the orings and check the boots they are good. I synced the carbs and the bike runs good now the power seems even all the way from idle to mid range but does not seem to have the extra power at high end feels the same from midrange to full throttle. Just wondering the best way to set high speed jets.

What mods if any does the bike have, and what jets are installed?Ed
To measure is to know.

Chris there are a couple of things I will address here.
The way the cams are ground on the 650s is such that they give very good torque, low to mid-range power and a flatter power band than some of the other GS models. Having said that though, my bike rockets up to and through the 8 grand mark with no problems.
You could do plug chops at full throttle to see if the main jets need to be altered a bit. I took mine up from #97.5 to #100 and it performs OK at one size larger. If you have a shaft drive 650 then the jetting will be different than the chain drive models like mine.
The other option is to raise the needles by 0.040" or one notch to make the mid-range a bit richer and see if that improves things. You have not mentioned which country you are from so I don't know if you have adjustable or non-adjustable needles.
Hope this helps.Comment
