Hello everyone, I just picked up an 02 LT-F250F the other day and have been in the process of tearing it down to fix some stuff- one of which was the cylinder base gasket leaking like a sieve. Well, I know why that is now, and I also discovered that someone had been in there before. I didn't take pictures, but it looks like it was probably run low on oil at some point, the cam journals and the "bearings" (for lack of a better term) in the head and the valve cover are totally wiped out, very deep grooves. From what I know it's very difficult to repair aluminum in this way, so I'm trying to figure out where to go next.
1. Have someone grind down the head and valve cover and fit actual bearings in since the aluminum is screwed, and have the cam ground down to match. I have no idea what this would cost.
2. Buy a replacement head+cam+valve cover.
#1 I was hoping someone might have some advice on, but #2 seems like it'll (probably) be the more cost effective option. However I'm running into some difficulty, it seems like the 2001 and 2002 models specifically use a different head part number, 11100-19B10, instead of 11100-19B01 like for all earlier models. What exactly is the difference between them? There are obviously far more of the earlier heads because it ran for over 10 years. Are they actually interchangeable? I've also noticed there are heads from the LT250EF that has 4 valve heads but also otherwise look identical. Would those work as well possibly? I'd like to not have to drop $500 on machine work or new heads on a $1300 quad that I'm already putting a bunch of new parts on. Oh, and it has a new piston and the cylinder itself looks pretty good too, as I said someone was in here before me.
Any help or advice would be greatly appreciated. I'll post pics of the carnage tomorrow.

I cant seem to find what this part is called. Can anyone point me in the right direction? I must be misinterpereting the parts catalog or something? I dont see it in the rear axle section. I think it may be in the rear brake assembly section? click link to view picture.

Anyone have a problem with the Polaris instrument cluster/speedometer frozen(part # 3280453) ? Mine is always showing R and slow now(see photo), Did it go bad or can you reset it or is something else the problem. It is on a 2004 Sportsman 500

another new guy. have a Yamaha Kodiak 700 and Polaris 500HO. My brother has a couple of Polaris. Summer in northern Michigan and ride some in Michigans UP where we have a cabin in backwoods. New to quads last year as far as owning one. Have been a jeeper for many years and modified/built several so have some mechanical ability, pretty knowledgable electrically too. Initially started reading the forums to find out what others using for lubes and common issues, other maintenance etc. Hopefully I can contribute.

I'm currently pulling my hair out over a customers 98 bayou 2x4 KLF300b. I've changed every electrical component on it twice and in a couple instances three times. Still no spark, I am baffled. Initially customer brought it to me complaining of a hard start no start situation and in fact, it wouldn't start. I changed the starter relay, spark plug, CDI box, and starter circuit relay after which it fired right up ran very well but then started having issues with the neutral switch/light where it wouldn't come on and wouldn't allow it start or even turn over. I found in the wiring harness a loose connection, I got it taken care of and secured and that solved the problem. So now that it would crank up again and run fine I called the customer over to test it out see what he thought as I've never heard it run before and I wanted to get his opinion on how it was running. Customer ride it around a little bit pulled it back on my carport and turned the key off and said it was great, and had never ran better or started so easily, then we set up a time for him to come pick it up the following day and he left. Well where he pulled it on my carport and shut it off was in the middle of the carport so I jumped back on it to park it off to the side, crank it up no problems put it in reverse went about maybe 18 inches and it stalled and ever since that point it has not had spark or run. I replaced the CDI box again with a better brand, I replaced the ignition coil twice put another starter relay on it and I've also changed out the stater and the pick up coil (pick up coil twice) and I'm just I'm lost I don't know what else to do to it. I've had this customers four wheeler for four months now whereas he's a patient guy I need to get it out of here so I can move on to something else. I've seen dozens of threads across different sites for off-road, 4 wheelers, ATVs, UTV's, whatever and they are all experiencing the same sort of issue but they never ever post hear the problem was or the fix. So I'm hoping somebody here has a little bit of knowledge on this particular issue sent since it seems to be so widespread. Thanks in advance for any help or suggestions.
