CV Carbs - Nightmare again !!
Posted: Sun Jul 12, 2009 6:09 pm
Hi lads,
I was previously here with the same username but havent been here for 2 years and needed to re-register, please read my problem:
Ive a GK73A GSXR 400 whic I have owned for 9 years. It has never done anything but break my heart! I got carbs for it, cdi's, rectifiers. a new engine and hours and hours of work!
Ive left it parked in the corner of the shed for 2 years and decided to drag it out yesterday. When it was parked it was finally going perfect and I didn't want to part with it!! Before I parked it I removed the carbs from the engine and turned them upside down and drained all the fuel from them. I then placed them back on the bike and its been parked since.
Yesterday I buy a new battery and put fuel in the carbs, they start pissing fuel everywhere so I take them off and flog the float bowls with a hammer and put them back on. I get the bike to fire but it keeps flooding and the carbs are still pissing fuel all over the garage floor
So I take them off completely and sit them on the bench, i fill a powerade bottle with fuel and plumb it to the inlet of the carbs. Fuel starts overflowing out the pipe at the top of the carbs between 2 and 3 and also out the filters (dyno'd stage 3 set up). I open the butter flies and fuel pisses from all the needles in all 4 carbs.
I open the float bowls and the internals are spotless (as to be expected with no fuel left inside) but the float bowls seem to be able to be removed very easily.
My question is this: Is it possible that the O-Rings that seal around the plastic pipes of the float bowls that allow fuel in and out.... could they have shrunk in the 2 years and now are not sealing and this is why fuel is pissing everywhere??
They seemed not to be sealing to me ad could be easily removed, nearly fall out of position. Has anyone come across this before?? Can these O-Ring kits be purchased?? Is this my problem?? Im not an expert and have had my fill of these carbs, but they were a good set and very hard to get for a GK73A now, probably impossible.
Thanks,
Karol
