Good morning all, I am heading to the Missoula MT area in July, I think the mountains around there are in the 7-8000 ft range. I am from Iowa where of course I'm much lower. My question is I have me XR setup with the snorkel removed, K&N filter, 160 main, with needle in third position "K&N", using the stock pipe. Doesn't run perfect here but I would like to know what I may need to do up in MT? I am taking both my DR 650, and the XR650 so I figure I'll have to do the same to the suzuki. Looking forward to some sweet mountain riding in the Lolo area. For those of you in that area any suggestions??
