Boycer67 Posted June 11, 2022 Share Posted June 11, 2022 Hi, I have an xs 250 with aftermarket filters & 2into1 exhaust, which runs ok when being revved, but when it is warm it won’t rev cleanly from tickover & often stalls if I blip the throttle. Can be really difficult to pull away with out really revving. I’ve cleaned the carbs with ultrasonic, so they are re clean & checked the timing is ok. Presume it is something to do with the jetting, but don’t know much about jetting & where to get jets if that is the case. Any help would be appreciated… cheers Link to comment Share on other sites More sharing options...
Moderator drewpy Posted June 12, 2022 Moderator Share Posted June 12, 2022 CV carbs need a liner airflow to work properly. I used the pipes to the original filters and popped some filter over them. to do a proper job, you'll need to get o a dyno to dial in the fuelling Link to comment Share on other sites More sharing options...
