OK... I completely cleaned and overhauled the carbs,rejetted to 90/122, removed h-box and mufflers now have straight pipes with baffles, and also went to pod filters, syched carbs and later found an electrical problem(partially blown metal fuse effected how bike ran) no more electrical gremlins. However now riding down the road between 3000-4000 rpm bike really runs like it has a miss and backfires out of right side, at times also feels like the right side completely shuts down... absolutely nothing, when this happens bike wont go over 4500 rpms or so and runs terrible. it actuallty died on me and would not restart, got home pulled the plugs, and they were dry and checked for spark and they both had spark. only thing i can think of is to put a spark tester on and go for a ride to see if the coil is cutting out when it runs bad but other than I am at a loss. Any help would be greatly appreciated.
