CBR250 Problems and Issues
I’ve got a 89 mc19, went over it cleaned the carbs, synced them, afr to 1 5/8 turns as per spec, coils test good, leads and plugs replaced. Still at idle it’s all over the place with a small miss, then at full throttle is quite gutless, hits 14k rpm, has power between 14 and 16 then breaks up...
