I recently bought a 93 f2, I put some work into it and my two middle plugs keep fouling. ( a white chaulky buildup) do I took my carbs off and my vacuum hoses are all in disorder, and missing The air vent control valve? Help please. Noob..
The first thing to do is determine if the symptoms are due to worn rings or bores.sorry to hi-jack the thread, but as far as rings and compression go my question is this:
If you have low compression and oily fouling on the plugs, then is the solution to simply install new rings? I'm thinking you would have to do new oversized pistons of 0.5mm overbore, no? to get compression back?
I have looked out of curiosity for 0.5mm oversized pistons as if someday I may rebuild my f4 motor. I have NOT been able to find a distributor, although I haven't performed an exhaustive search.
I thought that I have heard the cbr600 f4 sleeves are special lined or treated and can not be honed and over bored. Am I wrong?
Then again what kind of arse goes to the trouble of rebuilding a cbr600 motor right? :O Cheers!
