TOPIC:

So, the bike started puking fuel all over the floor a couple of days ago. I thought it was a bowl o-ring, turns out it was not. Seems it is the little O-rings on the connectors that provide the fuel between the carbs. Any idea where to get these? The carb part listings I have found don't have any pictures.

Thanks
Chuck

or ask partzilla...

That is for an e2, not h2. Are they same?

If you look up the part on Partzilla, information on what bikes the part fits comes up.

To answer your question though, yes, the E and H bike carbs are the same, so the O-rings will interchange.

And if you have an O-ring store in the area these are the various sized to rebuild the entire set of CV34 carbs...

Pilot Screw: 1.2 x 2.6
Pilot Plug: 1.5 x 2.8
Fuel Transfer Tubes: 2.0 x 5.5
Drain Screws: 1.4 x 4.0
Float Bowl: 2.0 x 67

BTW, industrial standard measurement method for O-rings is T (thickness) x ID (inside diameter), in this case measured in mm.

should be the same

A metric nitrile o-ring kit may have the needed sizes or sizes that are close enough. I got a kit from Harbor-Freight & it has come in handy for the carburetors, fuel tank, forks & a couple of other things. There are also viton rubber o-ring kits, but I've never had a problem with the nitrile rubber o-rings.

I called the local dealer last night and they have them on the shelf, so I guess I'll be running over there again after work to pick up 6 of them and maybe a couple spares. On the plus side I'm getting pretty good at putting those airbox boots back on.

Thanks for the tip. Dealer didn't actually have them so I stopped by Northern Tool and got a set of metric o rings

They had a 2mm x 5mm, which I figured was close enough - hard to believe that a Chinese o ring is within .5mm or that nearly 40 years ago that Japanese o rings were either. They fit nice and tight and no more leaks. I ordered a set of the right size just in case but I think I'll be fine
