mechmanuk Posted December 15, 2017 Share Posted December 15, 2017 Hi guys, i bought myself a dragstar last year (first time ive had a bike in a while), she is a nice looker with a vance and hynes exhaust system and sounds superb. I noticed that at higher speed when i released the throttle she would pop back through the exhaust, but was very loud. I was told to get a manometer and set the carbs up which i have done. I ride up the street and she runs beautiful with no backfiring atall. But when shes ticking over and i rev her, she will give a loud pop and sometimes you can see flames in the back of the exhaust? i assume this isnt normal or am i wrong? Any help or advice appreciated Quote Link to comment Share on other sites More sharing options...
