Thanks to help on here I now know my bike has the A55

It came with a old dellorto 14:12P carb...so I bought a new one to go on it thinking

the bike had the A35.

Currently the bike starts easy, idles good, is a big sluggish in the mid range but slowly builds up speed and will reach 36mph. To my knowledge, the only mod is the biturbo pipe.

A new A55 PHVA carb costs too much for me.

Would the Dellorto 15:15 be any better than what I have now?

Any info on what the numbers mean?

I have yet to try putting a bigger jet in the current carb, but I do intend to do that.

But Im wondering if the current carb can allow as much air/fuel as either of the

2 other carb options?
