hey, got an 07 grizzly 350 irs and its great and all, but I hate this autotransmission thing, it has no torque, or speed, tops out at like 25mph, what is wrong? am I missing something?? what do I need to do to open this beast up? Its a great atv, 4x4, diff lock, independant rear susp. It goes everywhere I want it to, but it doesnt do it quickly, and doesnt really feel like a fourwheeler should..help!
