I moved from western wa to Montana (gained 5000' ft elevation) and now I probably should change the jets in my bike. I've never fooled with a carb (other than adjusting idle) but see there's plenty of threads on here that walk you through the process. My question is - is it worth it to do it yourself? I figure it will probably cost me $100 to pay the shop to do it, but aren't the jetting kits about $60 anyway? I guess what I'm really asking is, how much of a pain in the butt is this to do?
