Re: Please help!! 1992 CBR 600 bogging down??
I’ve owned a 1994 CBR600 F3 and had real problems getting to run properly, a couple of things I would suggest you check, as it could be fuel starvation, firstly the fuel tap (petcock) these can fail and cause fueling issues, also check that the fuel tank breather is not blocked, a simple test is to run it with the fuel cap open. It could also be a jammed choke so it’s permanently on.
The other thing to check is the jetting, it may have been jetted for a different exhaust. IMO these bikes run much better completely standard.
Good luck, keep us updated.
