954 minor engine issues

Have a few issues with the engine since my accident when & T-boned a car at about 40mph.

Firstly then engine makes a loud matallic ticking noise that is proportional to engine revs. Its the same wheters the bikes hot or cold. I think it is coming from the exhaust header gaskets as the headers have been removed 3 times now without replacing the gaskets. What you guys think??

Next is the fast idle / automatic choke issue. When I start here up from cold she goes into fast idle mode & rev to about 2200RPM initially then the revs steadily climb to over 3000RPM over about 5 mins & will stay there until even after the coolant temp hits 100degC & the fan come on. After you ride her for 2 mins the revs come back to normal idle.

I think something might have been knoked out of calibration after the last smash. I have a Scottoiler fitted but I have checked to see that there were no vacuum tubes disconnected. Idle injectors may be way out of whack too. Any ideas where to start checked or what to do??

Next is the smoking issue. My mate says that when he is behind me & I'm at full acceleration he can see a blueish haze from the exhaust. He say its just bad enough to be noticeable - I must let him on my bike & I follow him to see for myself. Now I'm thinking oil & rings but I've had several hondas now with no engine issues. Could it be anythin else?? Dont want to strip the engine etc. but will be getting a dyno run soon enough.

Are all my issues linked?? I will synchronise the starter injectors soon & maybe check the valve clearances (not been done yet).

2002 CBR954RR
25k miles
Akra bolt on & K&N with custom PC3 map
142rwHP
2 serious front end accidents (1 lampost & 1 car)

Cheers guys for any help or advice.

Re: 954 minor engine issues

revs from cold - sounds like something sticking. check everything in the cold start circuit you'll need a workshop manual.

blue haze - are you sure it's blue and is the engine using oil? Could be a rich fuel map giving unburnt fuel grey smoke. need to be sure which before writing off the motor. Honda engines are generally v. reliable.

Re: 954 minor engine issues

Have the full manual & will check the cold start circuit as I'm servicing the bike. Have to check the synchronisation of the idle injectors anyway so I'll pull the cold start circuit out & check it out too.

Not sure if the smoke is blue - my non technical mate spotted it. The bike doesnt use any oil & I dont thrash it from cold. I do drive it hard but no harder than any other Honda I've had. The bike was customed mapped 2 years ago & the fuel at heavy throttle openings beyond 6k RPM wasnt adjusted by much. Have a feeling that it might be unburnt fuel but will see. Either way its more of an annoyance that anything else.

However in the future I wan to get some head work done & obviuosly dont want to do that if the motors dogy somewhere else. Might do a compression check to be on the dafe side.

I wouldn't worry about things like oil rings as these can't really get damaged in a T bone with a car.

It's more likely to do with the poor carb and cold start synch than anything else.
