CR carbs

[MarkCR750]

I just had a look on eBay , cruzinimage are selling them for less than £20 delivered, I would email them first though and check it will fit your model, the ad I saw just now said it was for a 1979 bike, probably the same part but they'll confirm it for you.

Just found the receipt in my emails, a German seller, it was £25, put the item number into eBay but nothing came up, so he must not be selling them now so cruzinimage is probably your best bet price wise.

Thanks,
I Did a search on cruzinimage / ebay , it seems they only have them for 1979 onwards,
so not sure if that will fit my 1977.

If you email them through eBay they'll tell you, they were selling GT250 pistons, I got them to confirm they'd fit my T250 and they did (early GT pistons are the same as T250) , or maybe someone on here knows if 1977 PD carbs are the same as 1979 ?

Thanks Mark

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.

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.

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
