Oil cooler systems are not usually high pressure so I'd suggest just taking one of the old lines to a shop and see if they can match up the fittings . If they have compatible ones they can easily fab up new lines for you. If you are going to an aftermarket cooler, you just need to be sure the fittings to the block are compatible. Use whatever hose you want, whether it be regular low pressure oil line hose or fancy steel braid covered. A shop that fabs hose can tell you whether high pressure hose is needed , but I doubt it .

Couldn't find a free service manual or wiring diagram . If you have no power to the lights or anything then the problem is in a mater relay if there is one , or in the ignition switch . Not turning over on the starter could be a safety switch or the transmission is not in neutral . Start at the battery positive and ground and trace the wires out . Check the neutral switch and safety kill switch. Check any and all relays . . Once you find out why the starter doesn't work with the start button you may also find why there is no spark. No spark could be the stator, pickup coil CDI box or coil. Most of those you have already replaced . Take it step by step from the battery out check connections for corrosion and wires for breaks . A wiring diagram helps a lot , but methodical elimination will do the job . You could try looking at the wiring diagrams of other arctic cat models for qa clue of how they are wired . Most likely they are all wired very similarly if not identically .

Use the chain to grip the sprocket to keep it from turning while you loosen the nut on the shaft.

Yes, it's a 1990. I have a 1991. There is a pdf of the service manual for it in the downloads section of the forum. I bought mine used 5 years ago, and paid a lot more than $200.... LOL.. You got a great machine if it wasn't abused. They're solid full time 4x4's with all the power all but the extreme riders need. They'll top out around 45 Mph if you really want to push them. One thing you want to check is the splines on the rear axle hubs. They wear out over time, especially if the hub nut was not kept tight enough.. I had to replace the rear axle and hubs on mine. The splines were worn out to the point ther left hub spun freely on the axle.

Welcome to the forum. I'm sure you'll enjoy the Bruin once you get it running . Hopefully just a good carb cleaning and most likely a fuel tank cleaning if it was stored with gas left in it, and a new battery will be all it needs to fire it up.

Try some small adjustments towards lean on the air screws. It sounds like it may be running a little on the rich side .

You need to look for 14" rims that will accept those tire widths , the same bolt pattern and offsets as the rims you have now. Here is the source of a chart to help you choose . http://www.mud-throwers.com/atv_wheel_chart

Knocking noises and metal in the oil sounds like a very expensive rebuild is in order. It could be from the rod, or the wrist pin on the piston and if either let go most likely it will destroy the block too. I'd take it to a shop to be diagnosed. If it breaks it'll mean an entirely new motor rather than a $1000 + dollar rebuild ..

Try contacting www.bikebandit.com and see if they can cross reference a hub from Honda or another manufacturer that uses a similar axle hub.

Found the download for the pdf of the '96 -'98 all model service manual and added it to the Polaris section of the repair manuals. Here is the direct link to it:

The bolts are most likely metric.. Find a standard bolt that is about the same size and then take it to a hardware store that stocks metric bolts. Choose metric ones that most closely compare to the standard bolt and then pick up a couple of each metric pitch for that bolt. I'd get bolts on either side of the one you take to compare. Without having one to compare, I'd guess the bolts are likely between 8mm and 10mm ( ~5/16" to ~3/8") and could be either a coarse or fine metric pitch. Here is a Kazuma parts source https://www.kazumausaparts.com/?gclid=CjwKEAjw_dTMBRDHusz5vZaV1g0SJACkjOf8bkdBoGa1G0Em4Jr3ufgXmL6eCTZRcEa7IFt6mH-5uhoC4kfw_wcB you could check with but most likely it would be cheaper to pick up a selection of bolts locally and see what fits.

The service manual is in the forum's Downloads section. (click "Browse / Downloads" ) Here is the link to the download:

The VIN should be stamped into the tube, not on a sticker. You may need to lightly sand the tube to bring it up.. The letters and numbers are not stamped very deep.

This video of BMW engines being manufactured in China very well illustrates where all the unskilled repetitive jobs have gone, and why they're not coming back in America or anywhere else. What BMW has done in China is being repeated by every industry everywhere. If it can be automated, it will be and except for a handful of operators the only people employed by those businesses will be tradesmen maintaining the robots. Education and trades training is far more important today than it has ever been.

Far too many sniff at Chinese ( and Taiwanese or Korean ) made products and declare them junk without having a clue what they are really like.. and at the same time tout some name brand North American products....... that are in fact manufactured in the countries they sniff at .. LOL. . Kymco is a good example of just one of those companies. Americans aren't the only ones to do it by the way .. I'm afraid Canadians can be just as prejudiced against Asian manufactured goods that come from anywhere other than Japan...... and I can remember when everyone was saying if it was made in Japan it was junk..... Until the Japanese started putting American and Canadian made cars especially to shame for quality. Optics and electronics both saw many Japanese brands become far superior to offerings made in North America. We're seeing the start of a repeat of that with today's China too . . Still lots of junk, but also a lot of top notch products .

Couldn't find a free one. There are downloads offered by pay sites

Look up Kymco.. They are Taiwanese, not mainland Chinese... They used to be with Honda before they went on their own. They build motors ans clutches for other big name brand Quads . They also build parts for BMW cars. Kymco happens to also be the official scooter and ATV supplier to the NHRA. Kawasaki and others use Kymco built parts, and Kawasaki also rebrands a Kymco scooter .. They are far from being a junk manufacturer. But call them junk as you wish, but those that condemn "Chinese " manufactured parts and equipment really should learn where far too many of their Good ole USA brand tools, machinery, electronics and many other things are made. Kymco manufactured clutches are used in several CTV applications. No, I don't own a Kymco, nor do I have any investment in them or any other Chinese or Taiwanese companies , but I really do think people , especially in the US need to learn where a lot of the parts and equipment they buy that has old time American names on it and have American parent companies should learn where so many components are made and how many items they buy with American brands on them are actually rebranded from an off shore manufacturer; many of them unheard of outside their home country. A lot of junk does come out of mainland China, but a lot of top notch things do too.. Unfortunately the same can be said of Canadian and American manufactured products. The country of origin doesn't necessarily determine whether a product is junk or not.
