Hi group! I need some help. brought this bike (95 zx600r) about 3 mo ago. It ran fine until one day it started bogging. So I cleaned carbs,sync them, rejetted to 150 and 155 (had 180's stock is 142)new needles and springs (called dynojet,they said the needles wern't theirs), new plugs. Also checked fuel pump output, coil and wire resistance all check good. No change in performance......but here's the kicker I put tape over most of the intake scoops and it runs great. I also checked the intake boots for leaks or cracks. same with vacuum slides. Also compresssion checked 165-180 psi. All emmision stuff has been removed, has a micron can, bike has 24,000 miles on it.
Anybody had this kind of problem.....please help, thank you.
