CR carbs

MarkCR750:
The diaphragm has 2 tabs on it, sort of Mickey Mouse ears, I have seen debates in the past as to whether these should both have holes in them, they should is the answer, the old one that I took out only had a hole in one ear, maybe that's why it wasn't working along with its generally poor condition.

I would have thought Dave Silvers would stock them, but according to the guy who built the bike they don't, I am not desperate just yet as the bike is starting up OK & I have checked the carbs with the filters off & the pump seems to be working, but not tried it on the road yet.
if anybody else know where to get hold of these accelerator pump diaphragms please pop-it on here..my bike is a 1977 CB 750.

Hello Greebo,

If you are still looking for the accelerator pump diaphragm they have them on CMSNL here:

http://www.cmsnl.com/honda-cb750k7-four-england_model14390/diaph-set-pump-rubberspring_16021mc9771p/#.VwzZLTGrHEY

They are €17.00, that's about £13.55 at the current exchange rate.

I think you will find that the unit for the '79 model is different as it had CV carbs, it looks to be different from the fische I have looked at anyway. The 'Micky Mouse ears' appear to be positioned differently.

All the Best,

Rob54.

Hi Rob

Thanks for the link, very use full.

I have had the old one out & it looks & seems OK Now, but I will hang onto the link &  send for one just in case, it does state in their advert they are for the K7

PS.,. I have been informed that these things all look the same but the rod on some of them is longer.

Cheers
Greebo
