Title: CR125M air screw setting
Post by: Doc on February 18, 2008, 08:57:29 pm

Could someone tell me the correct setting (approx) for the air screw on a '75 CR125M Keihin carb? any other details may help also. Thanks

Hi Cris,
"initial setting 1 1/4 turns out , screw in till falters then screw out slowly till  until engine begins  runs smoothly"

Thanks Noel, I was thinking it would be much the same as Mikuni's but it was about 3 turns out so I thought I'd best check incase they were different. I picked up a CR125M carb in extra good condition for a song. I was going to fit it to the TM125 as the carb I have fitted now (stock 28mm mikuni) has a huge flat spot just above idle I can't seem to get rid of. Thinking the poor old carb may simply be flogged out and the CR carb maybe a good replacement..cr's seem to like em'  ;) I'll have to lean it out somewhat as it's running super rich at the moment.
