Just got a 92 LT250R a few weeks back and Im wondering if there is a way to adjust the front suspension? I found a way to adjust the back to my liking as there was an O2 sensor. But the front is stiff as hell. Also I heard that Z400 wheels will fit my back tires? I want to get rid of the big bubble tires I have in the back and get some flatter/more treaded tires.
