tm24 carburetor (35 slow jet and 160 main jet)
malossi variator (7.0 gram rollers), delta clutch, clutch bell, and kevlar belt

I'm gear limited right now to 57 mph, and running 9.71:1 kitaco primary gears. The pipe is excellent for the midrange, and it's got more but I probably need to put in 9:1 gears to see more top end. It gets to 57 mph in a hurry.

I've managed to put 286 break-in miles on the cylinder, and just got over 50 mpg during the last tank of gas. Also, today was the first time I did a WOT on it.

I just swapped out the 7.0 gram rollers and put in the 6.0 gram set I ran yesterday. The heavier rollers are not as good with allowing the pipe to do it's thing. Also, replaced the OEM front pulley drive face with an aluminum Chameleon. The bike is responding very well, but the only downside is the exhaust seems a ton sharper in pitch. My neighbors must hate me now.

try a 30to1 mixture. give it that little more oil.with the aluminum cylinder you should be just right with the nice reving burial pipe.

Wow, kinda surprised today when I did a WOT on an open straight with an upward incline. Managed to hit 60 mph on 9.71 gears.

Greetings:

On those gears, that's spectacular. What RPM?

No rpm gauge, and the motor didn't sound too stressed.

richen that oil to gas mixture.30to1 or 28to1 if the air temps get hotter.if its more than 100degs out you might have to even run a richer mixture. get a tach,that way you can see where your power band is hitting and tune for that area. the trailtech tto tachs are around $37-$40 shipped off ebay.

I already switched it to a 30:1 mixture per your recommendation.
