I have set up a few bikes for flat track. There are a few things that determine the set up:

1. Are you racing ovals or a TT-type horseshoe config with left and right turns?
2. USA or foriegn? (counter clockwise or clockwise oval)
3. What class are you running? ( Some classes run a Knobby tire, no-swaybar rule.)

I set a trx450R up for a guy who runs locally. We did a std-travel setup with P.E.P.'s and went with stock width arms on the left side and a +2 arm on the right side to bias the weight to the inside of the turn. We also offset the Lonestar MX axle on the rear with the spacers as well. We used a modified Dura-Blue sway bar and adjusted the "jack" in the front end with threaded hiems on the bar and shock preload. I'll try to find some pics. I know American Star Manufacturing will make setups like this for you, call and talk to Mike tell him Jason from VA rec'd. them. They currently don't have a DS arm in their catalog but they are very reasonable about fabbing things up for people. Some people will run a -1" or -2" swing arm to get the bike to rotate in the slide, but we went with a stock swinger and P.E.P TT linkage kit. We always tried to keep the chain adjustment on the rear carrier in a manner where the axle rode at the highest point in the adjustment which netted us an add'l 3/4" drop in the rear.

Josh found this bike to be very Stable and fast and has won a few races between here and his duty station in Alabama. (military) He says he can enter the corners on most tracks on full power and use the front brakes to pitch the bike and the throttle to modulate the slide. Once he squares up to the corner exit he just feathers the clutch enough to let the tires grab and he fires off down the next straight. We have experimented with staggered tire setups for tight 1/4 mile tracks but he runs neutral now. A 300M oval is very tight. I'm assuming a Kart track?
