I've done one! Here ya go its a good starting point! Drop a tooth off the top gear! Take the pogo and the top cover Compress the spring and the top of the tube will come up, Pop 5 like 1 1/2" X 1/4" Orings over the top, be sure to lube them good! This will drop you front end! Next would be the exhaust! Cut the square can part, down both sides and across the bottom, about an inch from the edges! Then fold it up and you will see 2 pipes in 3 compartments! Cut both pipes off in the center section! Fold down and reweld! Then Ice picks atleast 144!

Don't cut the bottom of the can off, just the side! Is there a seperate can from pipe?
Leave the clutch alone and drop a tooth off the top gear in the chain case!

The most you would go safely id appx. 0.020 over bore.

Improving fuel flow through the engine will get you more gains than just more displacement will.
Smoothing up the transfer ports, champhering the edges and opening up the exhaust port slightly will net you at least 5 more ponies at very little cost.

The bore is fine just a bit of porting!
Ok if you look at the can the inlet and outlet have a perferated drop pipe inside. Simply drill a 1" hole from one side threw both pipes. Then just weld a plate over the hole on the out side!

Now what do i have to do to get all the drag out of the track. So the track roles very easy and so theres no drag.

Well the best way I've found is the Big Wheel kit in the back and Extravert Drivers up front! And go threw the boggies too!

Check all the bearings and replace any that do not spin freely. [including jack shaft and drive shaft]
Run the track as loose as it will go without ratcheting.
Check that the track is perfectly centered.

Most important thing for freeing up the track is the attack angle. You want the transition from the drivers to the suspension rails to be as flat as possible. That will free up more drag than just going through bearings and a big wheel kit. But all 3 would be best, if you really are serious than you pull everything apart and have all shafts trued and blue print the chassis so it's dead on centered for everything

An additional wheel up front would help too! The extraverted drivers lets you run the track real loose!
