Report "80 v50 II. here are a few issues. 1. The bike doesn't want to idle and when turning the air or idling screws it doesn't seem to make a difference at all. 2. When riding it is fine at first but when it has warmed dies on me and if i get it restarted it sounds as if it is only running on one cylinder. additional information The bike has just moved from 1350m's above sea leavel to the coast. So if anyone could give me the correct settings for the air and timing screws it would also be appreciated.(maybe this will sort the whole issue out not sure though)"
