mx2007

very simple......a good mix is 30ml of two stroke per litre of fuel....1/30..........

ok the xt is a great bike for commuting, but its very slow only producing 37KW.....this becomes a problem if u want to lift. u will be lucky to get 100mph if you are alone on the bike.....but again its reliable,light on fuel and the price is not that bad.

Is it worth while to fit a wr gearbox to a yz450.....???

gotta agree with the other guys...DT125....year mod???? that u'll need to get at a dealer
