yesterday i brought a cr 85 2002 for my son but when we went to look at it the guy said he replaced the fly wheel casing with a after market one but when he started it there was a loud rattle the fly wheel bolt had come off hense to say i got it cheap got all the other bits for the bike that needed doing namly bushes n bearings whent all through the bike found lots of loose bolts this guy did not look after the bike at all but put the bolt on with lock tight now but can not get a spark so could the bolt rattleing round have moved the pulsar .all the other bikes i have worked on are older and have points so im unsure of this set up cheers and happy new year matt
