brman Posted June 3, 2012 Report Share Posted June 3, 2012 I have just put a Athena big bore kit on with 1/8 mile drag port on. When I'm going above half throttle the left cylinder sounds like it stops firing it kind of sounds like its a rev limit but it only does it on the left side. I have swapped the carbs, reeds, and plug wires from side to side. I also have a dyna fs cdi box. Any ideas on what is going on? Quote Link to comment Share on other sites More sharing options...

Finch Posted June 4, 2012 Report Share Posted June 4, 2012 leak tester but one way to check intakes is while its running spray some carb cleaner around them and see if it revs up ( but not on your filter) Quote Link to comment Share on other sites More sharing options...
brman Posted June 4, 2012 Author Report Share Posted June 4, 2012 It wasnt on the intake side. I'll have to get a leak tester for the cylinder side tomorrow Quote Link to comment Share on other sites More sharing options...
Finch Posted June 4, 2012 Report Share Posted June 4, 2012 i dont know what else it could be besides cdi. i had the same prob about a month ago it was dirty prefillter but did the same thing chopped up in the higher rpms Quote Link to comment Share on other sites More sharing options...
Dixie normus Posted June 4, 2012 Report Share Posted June 4, 2012 Gotta hate chasing gremlins. Ricky stators are very bad about breaking up in the upper rpms Quote Link to comment Share on other sites More sharing options...
brman Posted June 4, 2012 Author Report Share Posted June 4, 2012 I got a buddy that's gonna let me try his cdi in the next day r so.

brman Posted June 4, 2012 Author Report Share Posted June 4, 2012 could a bad exhaust seal cause it? Quote Link to comment Share on other sites More sharing options...
