Started life as a bone stock low hour '01 WR, but now has different cams, exhausts, mild engine mods, and all the necessary changes to run flat track. Here she is! Still waiting on the Ron Wood Racing intake (ditches the whole airbox). All work was done by myself only, I laced the wheels, built the motor, lowered valved and set up suspension, everything. Its like a kid to me!
Last year I ran a bone stock motor, on original piston still (7 years on it:eek: ), with a mx style exhaust. I had people commenting on the way it ran on the big half mile (Lebanon Vally in NY), thinking it was highly modified. Wait till this year! Heres some pics from last season:
Anyone else who has a dirttracker, i'd love to see it!

I dont think I have the balls to slide around that hard dirt at speed
Do they ever run an open practice?
Im guessing the rims are 19 inch.
I can steal the rear rim from my YZ but I would have to lace up a 19 for the front.
Is there a 21 inch dirt track tire or is that silly?
I would have to go out on the track after Matt James daughter pulled off. It would be bad enough getting waxed by a girl,but a 12 year old girl would just crush my fragile ego.
She must be a tough chick to be racing a 400 4 stroke

There are tracks that allow 21" knobby up front, (don't make 21" dirttrack tire) but not a fun ride. When you ride a bike setup correctly for dirt track it wants to fall into the corner and kick the back end out. Bad setups hurt.
Unfortunately, here in Washington, most of the tracks are gone. Practice is the day of the race. For wheels, 19" front and rear are the norm and a must to get the correct tires. Its hard to believe, but when you are trying to go fast, you have to try and keep from sliding. Kind of a two wheel drift is the best way to discribe it.

On another note, that track looks very inviting with the moisture in it. We lost all of our cushion tracks and are down to blue groove garbage. When I was alot younger, I used to go to the tracks in Ohio, they were fun. Heres one of my old triumphs that still runs well.

Most guys take the rear rim on a YZ and put it on the front and put a wider rim on the back.

Just trying to understand this front tyre set up , why is the tyre wide when a speedway (solo bike) front tyre is very narrow , is it that the track surface is harder in flatrack ,or you want it to slide too?,what is the difference ?
The front tire choice is because of rules. This setup was for indoor 1/8 track
that has varied track conditions (hard and deep soft). You do want the front to be able to slide if need be.

Thats a nice looking 400. I've been keeping my eyes open for some AandA clamps to set my bike up with some R6 forks. That would bring my wheelbase close to the 54" mark where i'd like to be. I've made alot of changes to the bike since I took those pics, I'll have to update it soon. Hopefully I can break her in at Mototown before the first race of the season:ride:
My buddy still has 4 sets of these clamps. They come with top and bottom triple clamps, fork stem that uses the stock yamaha bearing, handle bar mounts and number plate mounts. Heres a picture of the set he has been using on his bike. With R6 straight axle forks the trail is about 4.00 inches.
