[QUOTE="OnAnySunday, post: 21239, member: 20641"] DEtune it? Why would he want to do that? How old is your brother? If he is younger (under 16) the big YZ may be too much for him! There isnt much i can think of to detune a bike. Maybe some kind of throttle limiter.... I put a set of Boyesen 'power reeds' on mine to give it a bit more bottom end, and reduce the top end hit. (seemed to make it more user friendly) But overall that gave it more power!

PS: He doesnt happen to have a spare piston and rod laying around there,does he??? [img]http://dirtrider.net/ubb2/biggrin.gif[/img] [/QUOTE]
