You betcha. In the details they sent to polaris they literally said the only thing they have left to change is the front susp, jackshaft, and track. They have a chief engineer interested in it apparently..

i’m wondering if the crank is out of phase or something crazy like that.
No matter what happens I’d sure like to know.. If it ever gets torn down and the problem figured out I’ll let it be known here too.
260 miles... I'm not sure why they didnt just tell you to finish the break in period and come back with any issues.
This is where I would have started-- if it revs out slowly and reaches peak rpm, but when you mash it it "bogs" I would install heavier weights or a softer primary spring (after the clutch has been inspected rollers, belt to sheave clearance, smooth movements of the moveable sheave, etc) to see if you can control the crank acceleration. If the ECU reads the crank acceleration as too fast, it assumes that the belt broke and retards the engine to keep the crank from spinning to the moon.
Unfortunately, troubleshooting is becoming a lost art. If DW doesn't tell the tech what the problem is, it is difficult for many to diagnose.
Exactly, they call it a soft rev. Motor revs too fast and puts it into a limp mode, no codes are thrown, also if you don't load the motor hard enough it will never reach peak RPM. I would probably start with a more aggressive Helix unless it's slipping in the primary, may need some belly buster weights or may need to add weight in the heel and belly. On my 16 800 I had the same problem, just not near as bad. I went from a straight 40 to a 60/40.36 and I could mash the throttle all the way. I believe SLP is running a 62/42.36.
And the winner is! ^^^^^
Ever since the 2020 flash came out these things are under-weight for clutching.
yes sorry
Searching for something else and came across this old thread. Anyone remember the outcome?

I was nervous when I read this as I picked up a holdover '20 800. On the first ride out it would initiate this "bog" and kill the power at higher rpm's. I only have 93 miles on it now but that computer controlled situation is starting to clear up.
