[QUOTE="Ol'89r, post: 1246796, member: 17212"] The big difference is the jetting and the ignition mapping. There are also some differences in the breathers. Here in Kalifornia, C.A.R.B. has designated that the U.S. bikes run so lean as to pass their standards that they have to be re-jetted just to run correctly. The ignition mapping is also different. This is why people cut the grey wire on their U.S. based WR's. The throttle stop on the U.S. WR will not allow the bike to get full throttle without trimming the stop. A few years ago, everyone was ordering these bikes from AU and NewZealand and trying to get them registered in Kalifornia. They were a good deal, about $1000 less when considering the exchange rate and they came with a new piston, rings and top end gasket set. C.A.R.B. caught on and made them illegal to register in Kalifornia at all. I have a couple of friends that own them and they can't take them anywhere but private tracks. Check your local laws before buying something you can't use. :ohmy: [/QUOTE]
