I was out riding last week and got stuck on a a rutted out hill climb. I clicked it into first and started to give it gas and my back tire was stuck on a rock so I gave it a little more gas. The front wheel started to come up so I backed off and the bike stalled. I thought maybe it was jetting because the bike was jetted at 2000 ft at 70 degrees and I was riding at 5000 ft and snow on the ground but it started right back up and ran great every place else. Any adjustments recommendations for the perch adjuster to avoid this?
