So 5 weeks ago I spent a ride trying to figure out a bog issue on my sled and it went away somewhat on it own……. This is frustrating and unresolved.
Great snow conditions with dry snow falling all day at 20 degrees F.
The symptoms were. Super rich low end, black streaks in the snow, burbling in the mid and would rev out perfect on top as long as i babied it through the lower rpm range. Spot on 8300-8400 rpm peak and would rip the hill.
No codes, no cel.
Swapped plugs after it went to one cylinder from a bog til stuck scenerio. (Had 3-4 that day) and it went back to running on 2 cylinders but intermittent bogging the rest of the day. (Had to recover a sled with shattered secondary so just rode around the symptoms)
Went home and checked everything over, changed plugs again, compression test (good) sealed up some areas that might have gotten snow on the belt? Basically no smoking gun.
Rode it 4 times since then with zero issues, runs sweet.
Now yesterday and today my brothers sled (identical to mine) starts doing the same exact thing.
Boggy, heavy streaks on snow, fouling plug on one side, no codes, rips when it’s at peak rpm. ??
We are both around 200-260 miles on them.
We have had zero issues with fuel pumps thus far.
3 rental patriot boost sleds along on the same trip zero issues. Running clean, burning the same gas, running the same oil.
His sled is going to the dealer when they open next week.
Anyone have any experience similar to this?
