\r\n \r\n I\'m so glad you are going to setup a YZ250F, Ryan!!! Because then I\'ll be able to buy all your parts and make mine into a sumo! (next thing I want to build) What year are you riding?
\n
\nOn my stock YZ with 48 rear sprocket, it was a little wrung out on the roads up at about 50mph. Over the winter I threw on a Athena 290 kit and put in WR 4th and 5th gears Best of both worlds! You just drop them in. You can even do a full WR tranny swap, but I like the stock 1-3 for offroad riding. Now it runs fine on the streets, except I\'m running knobbies and tubliss tubes that are way off balance so when I get up to about 40 it starts humping like crazy
\n
\nThe 290 gave it so much grunt on the low end! 1st-3rd it will lift the front without even trying! That\'s with stock porting and FMF powerbomb and powercore.
\n
\nRight now I\'m still planning, but I\'m thinking a custom sub frame/round bar/ rear pegs and a hand brake setup, then all I have to do is get a set of sumo wheels and swap between them and knobbies for the ultimate on road off road stunting machine! Then I\'ll need to rig some lights and a fan. And fab up a nice under tail exhaust for my custom subframe... and... I need to stop thinking about this and focus on my 636 build
\n
\nEDIT: Oh yeah, back on topic. I wonder why they didn\'t go with the reversed engine like the YZ450F?\r\n
