2017 all stock except Jaws BigShark pipe/Y-pipe w/boondocker controller.
Sled starts and runs 100% of the time, runs amazing pulling hard at 8400rpm for a few minutes of steady hard deep snow pulls etc but once really running hot and under heavy load at wide open throttle it can bog out, (sounds terrible and feels worse, almost like on one jug, or suffocating from plugged air intakes, even think I smell fuel so may still be throwing extra fuel?), anyways, from wide open throttle to maybe being able to hold 6000rpm..., stop and shut it off for a minute or two and it’ll do the same, run amazing for a few minutes until really hot and under load at full throttle/rpm and bog out again., repeat..
Talked to Greg at Jaws, Linderman, made programmer adjustments as recommended, even leaned it out a little extra at the top rpm to test on the hill.. better but still bogged. No O2 sensor or egt, just wondering if anyone has thoughts on what to check or adjust..
-will check exhaust valve cables/servo as mentioned in another post
-thoughts on the air intake scoop with the Jaws set-up?
-reeds? Seems like not the issue as it runs like a top at all rpm until really hot
-will change out plugs
-boondocker controller? Acting up when hot? (Mounted under goggle bag in front of the bars), or a bad ground etc?
Just looking feedback or ideas, especially if you’ve had the same set up and same issues. When it’s running solid it pulls like a freight train, but really sucks when you’re in chest deep pow on a climb and it bogs, makes it a challenge to not get stuck, gotta stay on your toes!
