So, I am going to post this in the Polaris Turbo section as well, but thought I'd see what opinions were on the stock end as well. Yesterday, after riding hard all day, I had one cylinder quit on me. The sled ran on one side (Mag) but I could not get the PTO side to fire. I have good compression on both sides, getting spark on both sides, but nothing from the PTO. It seemed like I was getting fuel on both sides, but I have not gotten into the sled yet, other than on the trail. I checked harnesses and all my electrics seemed ok. I did have an oil cap leak and had injector oil spill on the VR, and wire harnesses that are directly in front of the reservoir, but I can't imagine that that is the issue. I'm thinking possibly a bad injector, or a broken reed petal(s). Anyone got any suggestions/ideas. Thanks
