I purchased a 2019 1000-5 with 1200 miles from a friend. The sxs sat for ~1 yr with a full tank of fuel. When I went to look at it the battery was dead. The seller jump-started it and we took it for a drive. It wouldn't idle but otherwise seemed to run fine. I attributed it to fuel. I put SeaFoam in the tank and ran it through. Filled up again and dropped in Techron. It seemed like the idle was clearing up but then it started missing badly, strong smell of fuel, and excessive smoke from the tailpipe.
Rear plug was fouled, front was wet. Put in new plugs but it didn't help, so I took it to the Honda dealer. They found the battery and ECU to be bad and they think the ECU was damaged from jump-starting it. Honda wants to evaluate the ECM so they are providing a new one free of charge.
My research shows that jump-starting these units can fry the ECM. Further, low batteries, exasperated by running several accessories on the primary battery system, apparently can prematurely wear the clutch plates.
I hope to pick up the sxs this week and I will work on installing a dual battery system to drive the plow winch and various other accessories so the primary battery can be limited to sxs operation. The sxs will be on a battery maintainer when not in use.
This may be common knowledge for most but maybe it will help some other unsuspecting owner.
