Member Contributer Lannyl81 Posted December 23, 2019 Member Contributer Share Posted December 23, 2019 Searched for a carb kit for my '97, found two sources, both of which showed the contents; gasket for the float bowl, carb to air plenum, drain screw, float valve and a small "fat" O-ring...which I assumed to be for the pilot/fuel mixture screw. After purchasing a kit, then taking the carbs apart I found the pilot/fuel mixture screw O-ring to be considerably different. The O-rings I removed where about 1mm thick; the "fat" ones were 3+mm thick. I tried to get it to work, but would not....had to purchase additional O-rings. Now I am wondering if these "fat" O-rings were for somewhere else, perhaps the fuel enrichment/choke screw?....I did not take this apart....anyone happen to know? I have been emailing the company I got the kit from, which is in Poland, so there is a language barrier, trying to find-out more about these "fat" O-rings....not having much success. Appreciate any insight. Link to comment Share on other sites More sharing options...
Member Contributer Captain 80s Posted December 23, 2019 Member Contributer Share Posted December 23, 2019 Likely the o-rings for the float bowl drain screws. Link to comment Share on other sites More sharing options...
Member Contributer RC36B Posted December 23, 2019 Member Contributer Share Posted December 23, 2019 Or it could be the o-ring for the needle-assy in the slide piston Link to comment Share on other sites More sharing options...
Member Contributer Lannyl81 Posted January 6, 2020 Author Member Contributer Share Posted January 6, 2020 Not the O-ring for the drain screw, nor the O-ring for the slide needle.....these were included in the kit. I was able to measure the old O-rings and purchase new ones. The company in Poland responded saying they have sold these kits for years without any problems, so they refunded be $6. Of course the new O-rings were 3x times. Anyways all back together. Link to comment Share on other sites More sharing options...
Member Contributer RC36B Posted January 6, 2020 Member Contributer Share Posted January 6, 2020 But of course you ended up paying 3 times up 😞 We are lucky so many VFR 750 are still on the roads - that means kits are still around... I tried to find o-rings for the carburettors from o-ring suppliers... gave up - several have non-standard dimensions. Link to comment Share on other sites More sharing options...
