Power loss over all gears
I have checked forums and previous posts but can't find an issue that quite fits mine... here goes.. I have a zx9r '94, it was suffering issues idling at low revs and loss of power in the higher speeds as well but running fine in the mid range - after reading around the subject it seems this might be caused by air leakage around where the carb fits the engine - I sprayed some carb cleaner whilst engine running round this area and revs increased significantly. When I inspected the boots where they connect to the engine the rubber o-rings were not in good condition so I replaced with new. Now the issue seems worse - I have loss of power over all speeds in any gear - can barely get above 60mph in top gear and the bike dies at idle - I removed carbs and cleaned all the jets etc. but it has made zero difference. It's almost as though now it is not getting enough air - I'm just not sure what else to check at this point? Have also checked fuel tap, and tank breather - they are ok. Any help much appreciated. Thanks.
