Title: CR400 Mikuni Jetting
Post by: Duane799 on August 25, 2011, 10:11:57 am: Does anyone have jetting specs for a 36mm Mikuni for a 1970 CR400? The jetting was ok before I pulled it down but i can't read the numbers on the main or needle jets. Would like to get new jets in the correct range.
Thanks
Duane

Post by: oldyzman on August 25, 2011, 05:30:35 pm: Logic would be that the 36 would require leaner jetting than the 38, if you started at the 38 spec provided then it would be a safe starting point. I was advised this by a motorcycle mechanic when messing around with a 32 and 34 mm mikuni on a RM125. Will be interested if others agree on the principal. Maybe just consider using a 38 anyway...
