If you are experiencing a "half 1/2 lean issue" with your radio controlled nitro monster truck, truggy, buggy, etc,
you may want to look into changing the fuel tank.  Here's what I did - it seems to have pretty much fixed it for me...the white plastic material I used is a flexible plastic bondo board that you can get at any auto paint shop or maybe even at AutoZone...I used it because it's tough, flexible, and easily cut to shape.  I used Shoe Goo to glue it all together, I zip tied the shaped bondo board to the frame, used heavy duty velcro in the places shown. 

 

My goal was to get the tank as far away from those rear shocks as possible, reduce the 1/2 lean issue, clear the throttle linkage actuator, and sit as closely inward towards the motor as possible to help with balance.

After a good day of bashing, research, and development, I pretty much chalked this install as a success in fixing the 1/2 lean issue.  Another contributor you might want to check is the exhaust pipe.  I put a Werks dual chamber exhaust pipe on mine - this seemed to help, but didn't come near curing the problem as much as the fuel tank mod did.
