What carbs

[Markangels4]

Hi guys thanks for your help with my clutch issue, I wanted to ask again, for advice, are the carbs in attachment b34s or b38s, as I’m playing around with my jetting as I’m running pods and after market end cans , and what’s the best carb setting for them as in jet sizes please, thanks again and sorry to be a pain

They appear to be BS34's. Jetting depends on the bike, but perhaps pilot at 42.5-45 & main 137.5-145

Yes BS34's pull choke chrome caps quick tells.
the non adjustable needles may be too lean
Check the pods aren't blocking the ports on the intake bell, some do, resulting in shiite running.
Large intake volume improves running and horsepower, and vice versa.

Yeah, those pleated filters have a known history of being hard to tune for on CV carbs.... and just generally cantankerous. You might want to get some smooth foam ones and rejet with them.

1981 or later BS34. The crossover has been modified to two inputs. The design was for a single petcock into a tee connection.

Euro style BS34s? though I thought the RH carb fuel line fed from the outside on the euros

OOPS! I missed the Manchester part.

But the needles should be adjustable on euro BS34's
I also was thinking about US specs.
