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.

It starts and runs Ok but after a while the temp gage lights up and the fan fails to start. Any suggestions on where to start looking would be helpful. Thanks

So I recently cleaned my carb on my 1986 Quadrunner 230GE and had to replace my fuel pump and now it seems im getting to much air and I can not use carb to adjust it I believe its coming in from either my air box or one of the air ducts or possibly the clear air container that is under front of quad that runs into the air filter bag but im not sure. Has anyone have any experience with this happening quad will idle super high and nothing can lower it except blocking off a air duct that leads to main air box i also have to check again for any cracks or leaks in air lines and box and ducts any advice will help im stumped ! What else can cause to much air coming in ? Could it be a leak from engine or top end ?

When running for a while the rancher will shut off without the fan turning on. We then took it to dealer where it was started and warmed up. The fan came on at the dealer so they then replaced the fuel filter and fuel pump. We got it back and ran good for a few days with the fan coming on when needed. Now its back to shutting off before the fan ever comes on. It seems like the time the fan should come on the bike shuts off. It will start after letting it sit for a few minutes. Any ideas of the problem?

Tesla made an ATV to complement its Cybertruck they just showed off. Its called the Cyberquad and will only be available with the truck to start. Cool name "Cyberquad"... Has anyone seen this? Thoughts? All electric and plugs into the truck to charge.
Here's the Cybertruck introduction (Cyberquad ATV at 3:50)
