Hi everyone. I have been told I can use a keihin pwk 26mm on my 1963 bsa b40 to replace my we old (wornout) 376 monoblock.

Does anyone have any luck or experience with these keihin carbs that can give me some feedback on the matter?

I can get them new for about $100 and jetted correctly so they say.

Thanks in advance from Sunny So Cal

Cheers

Bob
