Hi,

Looking for a 275 carb to fit W/NG--i have what was on the bike when i bought it (a 289 with oval inlet) which was put on at some point in it's life.

thanks,

Tom Colbourne

You know you can buy a brand new 276 from Burlen, Tom? It's one size up, but any 275 you are likely to find might be a world of pain.

They do come up though. I have an eBay 275 on mine and it's in very good condition, though with the cam I have in the engine the 276 would probably give me better top end performance.

thanks for the info. I'll look into Burlen. I have a 1950 NH with a 276 so am quite familiar with those--the only difference i can figure is the 275 is 7/8 bore instead of 1" for the 276? The rest appears the same. The W/NG has a 7/8 bore head of course and quite low compression ratio (the piston is flat top).

Still looking for a 275 Amal--thanks folks. Any connections appeciated.

One of the things that is not so obvious is that the 276 is taller than the 275 - and there is precious little space above the carburettor for the cable adjusters.

Hi All--fYI i was able to find a 275 carb--still have the 289 if anybody needs one with an oval inlet.
