yea i only took it off for a few revs. and it was siting around for a year but i honestly highly doubt a mice nest got in there.once i get off wokr im going to try and just take the silencer of. and also if the coil was bad that means that under a load that it wouldnt give me a hot enough spark to burn correct? becuase the bike ideals like a freaking beast.
electrical troubles love to rear their ugly head under load
try that other coil and removing the pipe from the head
