Good advice on the chain! I was wondering that myself. On the throttle you can adjust it where the cable runs into the handle. Just loosen the nut closest to the handle then screw the other one in or out, depending on which loosens or tightens it. Just a thought!

 

The light throttle is one thing I love about my 400EX so you may just need to lube the cable and the lever pivot. I also love the way these wheelie just so easily and in control. Next you need to learn to hold her up on two side wheels, This is more fun than a rear wheelie. I have no courage to try a stoppie.
