yeah i have my bike modded. I've got the FRF full exhaust, 14 tooth front sprocket, Cam, Bigger Piston, jets, K&N Filter. I've been told that i can get about another 4 mph if i go down a couple of teeth in the back. I might be selling the bike though, i want the new honda 450. you guys can send me an emial if you might be interested in it. HotFocusOn18s@aol.com

 

nice got a pic?

 

what do u think a stock 400ex runs?

 

bout 65

 

I was clocked by a truck at 120km/h, i thnink that's about 75miles

 

you were going downhill right?

 

ive gotten 67 on my 300ex i dont think i was top speed though or it didnt fell likee it anyways

 

a good tip to find out if your at top speed is push the throttle thingy on the right handle bar all the way in final gear and give it a few seconds.

 

dude shut up it didnt feel as fast as i could go and i was 5th gear pinned

 

woh dont want to start flames just a little humor for laphs.
