my bike has developed a bad misfire, i have had a few other problem along the way ie a couple of seizures which i found out to be bad machining and a very tight fit on the piston.
i have been through everything so far to try and eliminate the misfire, the only thing i have not had tested yet is the cdi.
it feels like it is electrical as wont rev clean, almost like the ignition is cutting the spark at a certain rev.
has anyone had a similar issue before?
i remember seeing a youtube clip with exact same problem a while ago but cant find it or any info on it now

cheers
