Question about 1991 kawasaki ZXR 750
Hello, I am having a problem with my 1991 zx7. Randomly as I'm riding down the road say about 6000 rpms the bike will start sputtering and backfiring and the tach will flick sometimes down and sometimes up and sometimes to zero but it keeps running just not any power. It feels like it is only running on 2 or 3 cylinders. Have torn all into electrical and rebuilt carbs but can't figure it out. Any help would be greatly appreciated.

Sounds like an engine misfire, most likely due to a spark plug connector insulator leaking to the cylinder head.

SOURCE: Carb on 2005 kawasaki Bayou 250
remover all plastic/ rubber parts
then soak the whole carb body and slow jet in lacquer thinner
the slow speed jet/needle circuit needs to be cleaned with just 1 strand from 18 gauge copper wire going through all passages an holes pilot circuit in pic

your carbs are dirty. and probably need to be balanced also... bring the bike bto a garage and have them cleaned by a profesional.... also after market pipes don't give your bike the proper back pressure .. that can mess up your carbs timing

Fuel pump (if you have one) weak or has trash that can move . intermitten short, make sure all fuses are tight not just look good. Probably a re-occuring problem with trash or water in fuel.(fill fuel from clean fuel can ) If it was trash and cleaning carbs made a difference, clean tank filter and lines too.
