So I bought this bike about 6 months ago and in that time I've replaced the petcock, spark plugs and had the carbs rebuilt, checked the cam chain, tightened the drive chain and it still refuses to go above 65. I have a few suspicions though and wanted to see if you guys think they're valid. So the previous owner cut the mufflers off the tail pipe and put resonators on could that be causing issues? or could I have the wrong ignition timing? Did the shop that rebuilt the carbs do a bad job? Something else entirely? When it comes to fixing this I'm pretty stumped and don't know what to do so any help would be appreciated.
