I ve been advised by Burlen that if I go for a concentric, a 26mm Concentric carburetter is a good replacement with a 200 Main Jet, 106" Needle Jet and a No 4 Throttle Slide. Any experience by anyone with these settings? What are your thoughts?
Assuming you are taking about M20 fitment follow the settings and jet sizes for the Monobloc carb used on later M20s as a baseline set up...It should run OK on those settings with only minor adjustments at most...Ian
Hi, my experience with the 626 concentric is that, with the no 5 slide, the engine is jerking at low speed. Alsof the bike is not "picking up". The no.3 is working Just fine. Maybe I try the no.4 as adviced by Burlen.
Main jet is 230 (with airfilter).
