  1. I live in Utah (Salt Lake area) and I just got an 06' YZ450F. It is back firing bad. When I check the main jet it was #172...thats pretty rich. I also have a 03' WR450 that a shop jetted and they have a #150 in it. I guess I just need some clarification on altitude setting. Do you run richer or leaner at Higher altitude; and does back firing mean too rich or to lean? Thanks Zel
