I believe the rule of thumb is: one size leaner per 2500ft.??? My stock main is 350 and I run between 310 and 330. I mainly ride in denver. I ride a yz 125. Jetting depends on a variety of factors so there's no easy answer. I don't know much about 4 strokes and not sure if the same jetting rules apply. Try the FMF website or try to find an online version of the Clymer repair manual for your bike.

Check out Idaho Springs and the central city trail system. Also, There's and area called Four Mile which is near Buena Vista that is a good place to explore.

Have fun!
