I gear mine down 1 tooth on the rear, add a tooth. 50 to 51. I like the power down low and it closes up the spacing a bit. As far as top speed goes, it probably tops out in the low 70's. I did put the E Line coil on it and tried it out this weekend. Smoothed out the power a bit and made it more manageable. Im going to install a Moto Tasinari reed cage this weekend, Ill let you know how it works. Rob
you did say 250 didnt you? I have clocked my old xr 200 at 59 mph topped out and my cr 250 blow past it at 59 liek its standing still. I have out run a 400ex too on a strait away, i think he was gaining slowly, but after 3/4 mile we ran outta road.
