hi i have a 1991 GSXR400 and have very limited knowledge as im a new rider. i have trouble starting it even when bumped. when it (eventually!) starts, it idles and sounds reasonably healthy but as soon as i go to ride it stalls and fails to start again. i had it serviced and carbs cleaned in Nov but has been only started a few times since and petrol may be stale? will redex help? can anyone help with this?? any advise will be gratefully received!! many thanks
Andy

Did you replace the dredded O-rings in the carbs? If not then there is your likely problem.

ill have to contact my mechanic to find that out, if not, is that an easy thing to check and replace myself??

As long as you are able to pull the carb insides apart and put it all back together again (with new O-rings of course) then it is a fairly easy job if you take your time. To be honest the hardest part is usually getting at and removing/re-installing the carbs from the bike.

excellent im going to give that a go. ive found a page of instructions for removing carbs. the set of o-rings ive found do not include 'bowl gaskets', is it vital i replace these too?

Hi J,
If the o'rings are from fleebay they are from me, regards bowl gaskets rf600 are the same but about £6 each so i only change em if they leak.
Chris.

cheers for the o rings mate and the advice from you both but ive made a decision to sale the bike as it is. havent got the time to have it fixed and i will potentially be missing many riding weekends trying to get my head round it. new bike on the way. look out for my gixxer on ebay very soon.

Shame

Joner: u say the RF 600 Float boal gaskets are the same, is the Jet holder crush gasket also the same ??

Hi Andre,
This is a link to the RF600 kit so you can see if the gasket is the same. Think it is just the bowl and the o'rings altho i sell the o'rings for £11.
