New to group. Looking for help in carb selection/settings for my 1969 Saracen 125. Motor number is 125/5A GS. Picked up a OKO carb, bike ran pretty well, found out carb is not legal for AHRMA events. Any advise on carb size, jetting, fuel/oil ratio would be greatly appreciated.
Thank you

John,
125 Sachs engines used 24mm, 26mm, and 27.5mm Bing carburetors. (26 may be the easiest to find).
Make sure when choosing a carb, that it fits the spigot on the cylinder.
Pilot / idle jet - 35, 40.
Main jet - 135, 140.
Golden Spectro 2-stroke oil. 50:1 or 42:1

I have rebuilt Bing 24 and 26mm with new jets and slide.
