Hey everyone this is my first forum post on here, so I'm hoping that I'll get some helpful responses. I just put a Dellorto 15.15 carb on my 1977 Batavus Starflite. Prior to the new carb I was only achieving about 20mph or so now I average about 22-23mph. I was wondering if anyone could point me in a direction to get more out of this carb. BTW there is a 68 jet in it too. Any advice would be greatly appreciated thanks.
