H1E Carb Top Cap Rubber Seal

Hello Everyone,

Does anyone happen to know where I can get some top seals for my H1E carburettors. The seal I mean is the thin one with the notch cut out that fits inside the top screw cap. All I can find is complete carb overhaul kits which is a bit much as I only need the rubbers.



Thanks for any info on that.

I'm not completely sure if you mean the rubber cap covering the idle speed adjuster, but if you do then a set of 3 are available from KawaTripleParts for £30.

Hi Charlie,

I mean the rubber that fits inside the top cap, if that makes sense.



Cheers

Nige, 'cos I'm old and dumb it's best to make sure we're talking about exactly the same item! See attachments (I hope!)

Charlie,

Yes the part you circled is the one. Not finding those parts by themselves unfortunately.

I don't fit them, they are just a pain in the arse and don''t do anything useful in my experience.

Malc,


The rubber one would be great, apologies for the slow response.
