thanks all, got fixed up with baffle.
i,d been warned about these tuonos being temperamental,but i still bought it cos i luv the look of it,ha ha.its got a brand new battery supplied buy the seller,but refusing to start when bin left for a while,i am keeping it on trickle charge when not in use as i know they need plenty power to spark big v twin into life.I think ive read somewhere a more powerful battery could be the answer,or maybe a quality top up charger ,as mine just a cheapy im thinking its not up to the job.Any advice gratefully accepted from a newbie hoping im gona be riding and not polishing all summer, ha ha
