Found one on Ebay: Link didnt copy New OEM Polaris Sportsman/Scrambler Rear Rack - 2879139

I usually find aftermarket racks on Amazon, they are very well made, and reasonable, haven't looked for the Polaris, but they should have them, Rocky Mountain ATV has Polaris OEM parts they may also have aftermarket to fit.

And she started right away Thanks for your invaluable help every single one of you 🙏 I learned a lot in the process, I'm way more confident when it comes to simple troubleshooting of these things now. Most important lesson could probably be found in that the "old" coil seemed to work judging from the resistance tests, but when tested in isolation it didn't give a spark. Special thanks for your insights @Mech, really appreciate knowing more about the theory behind it. I'll send a video of her running tomorrow for a nice wrap up of this thread. Will also mark one of the posts describing how to bench test the ignition coil as the solution for clarity. /Pär

The higher resistance primary reading means it has more, finer, windings, and so draws less current Params. That's ok as long as the secondary windings are in a suitable ratio to the primary; so the step up in voltage is enough to throw the spark. If it was a multi cylinder and had to throw more sparks per second then it's an advantage to have thicker wires so they carry a heavier current and so magnetically saturate the iron core faster. In this case, of a slow revving single cylinder, there is plenty of time for the magnetic field to build, and so a low current through a lot of fine windings will do the job adequately and without using too much power. The conventional coil in a 12v system builds up a magnetic field in the core relatively slowly while the power is flowing, then cuts the power and the rapidly collapsing field cutting through the secondary windings induces a high voltage. In the cdi system the capacitor gets charged up to hundreds of volts and is then discharged through the primary windings, and the rapidly expanding magnetic field cutting across the secondary windings induces the high voltage. One system induces the spark on the expanding magnetic field, and the other uses the collapsing magnetic field. The coils are different. The resistor cap is not very critical and isn't dictated by the primary resistance. The overall resistance of the lead, cap and plug is normally about 25Kohms.

And we have a spark ✅ I have to get some fresh gas before starting it up though The coil primary resistance is higher than the spec, any clues about how that affects the system? I'm thinking that the higher resistance maybe should be matched with a spark plug cap with a resistance that is lower than the spec. (I have little to none knowledge about electricity) So excited to get her running!! /Pär spark.mp4

I reckon if it was revved up with a strobe timing light attached, the spark would stop happening as the rev limit is reached. That's what it sounds like to me listening to the downloaded video..

Big Bear 350, that should be a fun project, depending on the state of disrepair it is in. The Big Bear was introduced in 1988 to compete with Hondas 4 Trax 4x4, it was Yamahas first 4x4 ATV, it was produced for 1988 to 1999, they were tough as nails and along with the Honda set the standards for 4x4 ATVs. Did not have a very fast top end because of the low gearing, they were made more for work and hunting and boasted pulling power of 900lbs.

Yes please don't cut it if frame is bent as such when you cut the metal will try to go back to it original form as most metal will because of memory of metal tube ,could heat with torch back and forth to release structure bend a little bit with the pull of chain block to solid structure of sorts ,yes cutting will be a whole big can of worms you don't won't.

I would go over the steel strip with 600 to 1000 grit sandpaper just to get crud off with maybe WD40 or some sort of contact cleaner, I would do the same with the little metal button on the pickup coil, just to get them clean and polished. Even though the metal button on mine was pointed toward the stator it was upside down sticking above the side cover, that's probably not you problem because you are getting some spark, I was getting nothing, but I would clean the 2 metal pieces and any rust you see while you are in there.

I do have the paper manual and yes I will look at the diagram in it to find the ground connections I should check
