I had a chunk of wood stuck in my reed valve that would cause an intermittent issue and cause it to only run on 1 cylinder. Might be worth checking the reeds.
The SLP pipe kit works well on these machines.
I rode an 07 M8 for a few years. I had a BDX Black Boxx intake and a Speedwerx y-pipe, The Thing can. I thought it worked pretty well.
The best upgrade I did was a 2.5" CE track. I would add traction prior to any power adders.
For clutching, you...
A friend had the same symptoms before his fuel pump finally quit. It would run fine then die on the trail and we would have to dump a cap full of fuel in each cylinder then it would go for a little while again.
There is no way I would register a used OHV and pay the tax. 7% or 12% on a $10,000 vehicle would be $700 or $1,200, respectively. I take my chances and the fines so far have never even came close.
I will however buy liability, fire & theft insurance....
Gripper skis for sale at the link above. I'll even throw in the longer bolts to fit M Series or Proclimb :)

I have a set of like new gripper skis if someone wants to purchase. They are on a 2010 M8 right now, not sure what the previous owner had to do to make them fit.
Send me a PM.
What year M1000? I know a guy that ran the black boxx on an 07 and again on an 09. The 07 loved it, the 09 bogged. He also had full SLP exhaust on both machines. Boondocker on the 07 and PCV on the 09.
Checked all connections and applied dielectric grease to start. That didn't fix the problem and everything looked to be dry and in good shape.
Next I cleared the codes in the computer by following directions in the thread below. Problem solved! Still not sure what caused the problem but easy...
