Accelaretor pump gasket

[Jokke75]

Took my carb off for re-jetting and noticed that the accelaretor pump gasket is broken, please see the picture. Do I have any options but to buy a new rod set? They ask 85€ = $100 for that set here in Europe..

that part is not available without buying the whole set from yamaha. I would try calling Mikuni customer support.

Thanks, Dave, I will investigate who represents Mikuni here, if anyone, and try to source only the gasket somehow. Luckily there’s no real rush as we just had first snow here over the night..

There's a guy on FB with some carb parts "Charles Cole Ferriss"

[davej]

Might even start a thread and ask if anyone here has an old carb parts box that might have just that part. "Duke" might be a good person to ask.

Thanks, guys, really appreciated!

its just a neoprene oring

I bought a black rubber "O" ring from ACE hardware. It costs .25 cents!
It fit perfectly.

[Jokke75]

Yeah it’s just a rubber gasket but not easy to find one that fits..how would you guys imagine that broken gasket affected the bike..no accelaretor pump effect at all, I guess? I don’t think air leaks inside from above as there’s fuel in the pump so air cannot go in..only gasoline leak, which was surprisingly small..but of course it’s above float level.

I was wondering if you found somewhere that has a good o-ring assortment if you couldn't come up with a proper sized one?

[Jokke75]

Thanks for all the help, Deephate, I think I will visit some bike/RC shops to check for some small rod/cable gaskets and see if I could
modify something to fit. Lots of time now during off season so no rush..

The gasket your picture shows, I've replaced it with a HSR 42 Mikuni carb gasket. It will work good and be a lot cheaper.
