My pioneer starts great, idles ok, but backfires constantly while trying to rev or drive.

It has 2 spark plugs for the same cylinder,  and when I hook my tachometer to the wires the top wire shows 700-800 RPM , and  the bottom wire shows 1500-1600.

Is my coil bad, or is this normal?

      I just purchased a 2023 Honda Pioneer a couple of weeks ago and had the hard roof and a front Honda Pioneer windshield installed at the shop before taking ownership. As things are drying up here in NC, the grass and dust are beginning to fly right through the back of the cab while driving. I was wondering if anyone has any good recommendations on rear windshields, dust panels, or mesh screens to help stop this?
      Thanks a lot!

      So with seat belt on  I can only get up to 20mph then it starts bucking until I get under 20 again. Diconnected the seatbelt and same thing. Reconnected seatbelt and unplugged speed sensor. Zoom..it flies. But now I have no speedometer. I have a new speedometer sensor on the way..any other ideas?

      I am about 6 months in to owning my 520. It is used mainly to run back and forth to our barn and shop. Occasionally, I run it up and down a few fairly steep hills on the property. One day, as I was going up one of the hills, the motor started sputtering and a tremendous amount of smoke was coming out of the exhaust. I was near the top and it made it (sputtering) up. Once back on the flat, I made it home. I loaded it on the trailer and took it back to the dealer. They said they checked everything out and found no issues. Over the next month or so, I only had occasion to go up hills once or twice with no issue. Then one day, again as I was going up a hill, the engine sputtered, giant plume of white smoke and then the engine died. 30 seconds later, started up and made it to the top. Repeated the route (down and up) and the same thing happened again. Called the dealer and their head of service said he would come out and wanted to see it first hand. He came out a few days later and repeated the route several time and it never happened with him in it. I had videoed the whole thing on one of the times it happened to me, but since it happens intermittently, could not produce it when he was here. I told him that I had checked the temperature, the oil level and the antifreeze level after each occurrence and they were normal. I asked him to call Kubota and ask what the possibilities were and that I am not fond of it dying on the hill and blowing the smoke and I didn't want to wait until something catastrophic happened to figure it out. When I followed up, they had no answers (which doesn't exactly please me). Any ideas? The attached photo was the start of the smoking. Didn't know how to upload the video of the whole thing, but it fogged the whole area.

      I bought this SxS brand new.  A couple of years after I bought it, I became disabled.  Thus it has only 47 miles and around 16 hours of use.  I have no need to keep the SxS.  I am in Foley, Alabama.  It is very hard for me to get in out of the Challenger.  I would like to sell the set, 2019 Challenger 400, trailer and uninstalled winch (this was bought brand new as well, someone was supposed to help this newbie install and we never got around to doing this). I want  $6500 for the whole set OBO (Serious offers only).

      I have a Coleman 550.  Was having problems to start with where it would start and then shut off after a couple tries. It would take off and be good. It then got to a point where it would not start at all. I replaced the fuel injection twice the second time I replaced it I noticed a mouse or something had chewed one of the wires that connect the electrical to the fuel injector. . So two-part question first does anybody have a part number for that wire harness?  Second, any other ideas after I fix the wire harness permanently on what could keep it from starting I have gas flow up to the fuel injector.
