Young Guns Racing Posted August 13, 2013 Report Share Posted August 13, 2013 Alright if im.gathering what I could understand from it all, thr bike runs good sometimes and sometimes not. Cuts off randomly and whatnot. Step one run a compression test. Secondly test your ignition system, and third go for a leakdown test (my bet to where ur issue is at) and see if you have an air leak. If you do idc how much u tune and jet it. She will never run correctlym good luck Quote Link to comment Share on other sites More sharing options...

Young Guns Racing Posted August 14, 2013 Report Share Posted August 14, 2013 Sounds like a wiring issue, if the tors and parking break systems havnt already been taken care of then delete them to start with. Secondly test your ignition system via a service manual. Check for grounds and such as well Quote Link to comment Share on other sites More sharing options...
