I have an 82 XT550 and it tops out on the highway at ~4500rpm at ~110kph. I understand that it is probably one of the tamer 27hp versions, but want to know how to get it to an unrestricted state (and actually rev the thing past 5000).
Any help is very appreciated (think I´m gonna get run over on the highway if I can´t get the speed up on it.
