I know its a two up but I would like to get alittle more speed out of my 05 500 TRV. I removed the throttle screw, any other ideas? I am tired of the 400's leaving me in the back. Although its great to put the front guard on their back to push them through the mud.

 

My TRV works great , w 26 inch mudzilla's and clutch kit it will do 50 mph. Stock performance isn't the best. Mind would not even spin the tires (is it just on take off or top end). Now in the mud I roaster tail. I miss the speed of my modified 580 predator but my back says more riding time for you.
