Hey guys, a friend of mine is having issues with his bike revving past about 1/4 throttle. He posted on kawiforums but no replies. Hes tearing his hair out, anyone have an idea?
"Hello all,
I am looking for some help with a bike I am putting together that has me chasing myself in circles trying to figure out. It is a 91 ZX6c that was a salvage and I have put together from a few parts bikes.
The problem is that the bike will run and even idle fine but will not pull if given more than about 1/4 throttle. even just free reving it it wont go past about 6k rpm. I have tried two sets of carbs, both of questionable condition, but both with the stock 105 main and 35 pilot jets. I have torn down both sets of carbs multiple times now and they are clean (as best I can see). There is good spark from both the coils and the plugs are brand new, gapped to the factory .028 inch spec.
I really don't know if this is the proper place to post this question, but I figured that there may be a simple solution to this problem that I am overlooking that is specific to this generation of bike.
Thanks,
Owen"
