running rough at low rpms

Recommended Posts

i have a 98 banshee with exhaust, trinity single carb, and a cool head. i was riding this weekend and it started acting up. it wont idle without giving it gas and runs rough at lower rpms. Seems like the left cylinder is misfiring the right seems to be fine. When you give it more gas, it revs higher and runs great. i switched the plugs and it still did it. I also took the reed valves and checked them but they seem fine. any ideas on what it could be?

Check your reeds while you have the carb off.

i will clean the jet and carb tomorrow but i didn't think it would be the carb since i am only running one, or am i wrong. I checked the reeds already and they seem to be fine.

Did you "really" clean the pilots? Remove, inspect, clean, blow compressed air through, reinspect, install??

 

How is that carb sync looking? Slides come up at the same rate and time?

:huh: haqhahahahahahahahah :yelrotflmao: :rolleyes:

 

 

seriously though, swap your plug wires and see if it's still the same side. after that, i'd do a compression test.

well i since i have a single carb kit i would say its pretty much synced with itself and the one slide slides fine

 

 

Yea, people dont like to read before they respond.

 

Make sure your choke tube is connected as well - me being an asshole.

 

As mentioned above switch your coils from left to right and see if the misfire changes. Might wanna throw some new plugs in too. Compression check wouldnt hurt either.
