Ok little background bought sled 2 months ago from a guy in WA was a 940 with 156 miles. Took it out first day within mile pickup it seized. Went through BDX purchased new top end 950 per their recommendation. Had installed by cat dealer. Picked up tookout first ride bebopped up the trail for about 8 miles started working into the throttle and was not opening up possibly running on one cylinder. So towed back to pickup took to cat they tested stator, ecm and checked reeds and all checked out good. Unplugged powercomander and said it ran better and relocated ground. Said it was good and can't find anything wrong. Took out today seemed to run decent but has a terrible bog in midrange and sounds like hell. If I keep hammering thorottle it pulls hard and runs good. If I hold mid for more than 10-15 seconds it's starts running like ****. Brought it home tore pipe off pulled plugs mag side look pretty good lots of oil, which is to be expected running first tank a 32:1. PTO side look almost unburnt and wet. Which is what I noticed before I took to cat the second time as well. So as far as my knowledge goes if it were coil it would give a code and I replaced injectors from different sled with no change. I'm looking for any advise as cat has no idea and BDX has not come up with a solution either. Also put compression gauge on pto side is about 124 and mag side is about 115 guessing this could be from rings not being seated all the way is this possible. Adding pictures of plugs and write up from cat. Thanks in advance
