Mine is a yz but should be the same. Due to the very low humitity here in Utah you will probably end up more rich than you would expect. I did the bk mod, dropped the needle one, 158 on the main. In the summer 80-100 i drop the pj to a 40, once it starts dropping below 70, I put the 42 back in, PScrew at 1.25 out. Works pretty well. I could go leaner, but then cold days really lean out the bike. Kind of a catch-all jetting. It probably would work great if all you did was drop the needle one until temps climb up in the spring.
You a real limey?
