XJ750 Posted August 3, 2009 Share Posted August 3, 2009 Hello, I just bought 1984 yamaha XJ 750R, the motorcycle specialist cleaned the carburator, now it is runing perfectly for rpm 1000, but after i ride it for over an hour and it warms up, the rpm goes up to 3000 and stay between 2500 and 3000, if i shut it off for an hour and start it again, it will goes back to 1000 rpm. anyone would know what the problem could be? thanks JAY Link to comment Share on other sites More sharing options...
