I have the ‘72 H2 up on the bench and its time to replace the carb float valves. The bike has stock carbs. They each take turns peeing on the ground when I first turn the gas on. They stop once the bike is running but it makes a mess. I normally order carb parts from Niche cycle using Mikuni part numbers and get genuine Mikuni, but I can’t seem to find the number for these. I’m leery about using aftermarket carb parts because of the low quality of a lot of it. I only want to do this job once.
So I need a Mikuni part number or a good aftermarket brand I can trust.

Thanks
Mark

I replaced mine with Mikuni Viton rubber tipped needle and seat sets, but can't seem to come up with a part number here, someone else will chime in and know I hope.

I never remember which is which but niche cycle should have them.

Pls. let us know what the p/n is.

clips/height/threads are not matching up to what some need on the viton tipped valves.

I searched through my archived email but could not find where I purchased the viton tipped float needles for my H2. Possibly Niche Cycle?? They work fantastic.

Yes Nichecycle

Niche Cycle is a top notch recommended seller! Thanks for confirming. I’ve had them on my stock carbs for 4-5 years with no issues or leaks. That is saying something for an H2.
