Ok, so I bought this scream of a deal the other day - a 94 King Quad 300 for $40.00. It's been sitting outside with no carburetor on it for about a year. Its rusty, missing some parts, wiring is all cut up and spliced etc. No seat, no racks but the plastic is all there minus the headlight housing. Anyway, who can pass up a $40.00 quad right? I get it home and looked at the sight glass for oil level, it's about 1/2 oil and 1/2 water. I drain it, refill it and turn the motor by hand (recoil starter is missing) and it turns over just fine. I worked on the wiring for about an hour and got it to turn over with the electric starter and got enough of it sorted out to get a spark. Did a quick compression test, 70 lbs. Wet test bumped it up to 90. Ok, so rings and cylinder washed out with water for a year, not too surprised. I thought 'what the hell' and sprayed some starting fluid in it and it ran for about 2 seconds - enough to show it's got life. Since then the compression has gotten worse, I can't get enough pressure to activate the carb diaphragm, therefore no fuel pump either. The compression is now around 60.
Anyway, my question is....is it worth it to try to get this thing going? I tore the top end down today and the cam and one of the rockers is pretty worn. I figured a top end job would be about $100 or so, depending on the condition of the cylinder but I'll probably have to put a cam and rockers in it as well. Doing some research on ebay I figure I'll have to spend about $500-$700 to make the whole machine right again. Much less just to make it run and use as-is but I won't really like it until it's right. I don't mind doing the work, I actually enjoy it but I'm concerned about what all that water did to the rest of the internals, I can't really test it all out until I can make it run.
I know it's a basket case but I'm not into it much at all, even if I do the top end and find something else wrong I'm still not out much. I'm leaning toward ordering the top end parts and going from there unless you can convince me otherwise - any way to check the rest of the internals without tearing it down? I plan on flushing the oil cooler before I do another oil change, I've drained it twice now and it gets milky almost immediately just turning the starter - I suspect the oil cooler is polluted badly.
I'll get some pictures today if anyone want to see them.
thanks!

Does anyone know how to access the check engine codes on a 2018 450 sportsman. Just changed battery and spark plug . It runs fine but the light is on and I need this to plow snow and need it reliable. Any ideas . Thanks

Anyone know where I can get a free download? I had one a month or so ago on my 'puter but one day it flipped out and I lost it. I gotta put the top end of this 450 together (hopefully today) and I need some info. I've searched and searched this morning, but, I can't find one. Thanks!

It's time to replace the shocks and struts. Looking for some stiffer springs than the OEM as I use this for farm work and I put heavy loads on the rear and haul small trailers frequently. I've seen a couple aftermarket offerings that say they're 10% or so heavier duty. Any other options for something a little stronger / stiffer? Thanks.

The saga of the fan continues.
The Pin attempt in the fan shaft failed. I then moved on to trying to weld the fan hub to the fan shaft. I took it for a run the weld broke. Now it was truly F'ed. To recap the dealer price, they want $400 + CND for a replacement fan assembly.
I searched all sorts of after market places and no one carried one. Ebay had some used ones but they were $120 USD + Conversion rate for something as old as what I have. I went to Amazon and eventually settled on this.

What I found... and was amazed... was that the fan mounted to the Suzuki fan assembly bracket. I was prepared to manufacture my own mount conversions... It also came with "Harpoon mounts" (nylon zip tie like things that go straight through the rad. Anyways it mounted to the original bracket. It fit perfectly. Cut the electrical plug off replaced it with the Suzuki... all good. Let the quad heat up, thermo coupler kicked in the fan circuit, polarity was right... all was good.... Fan is under the circuit fuse rating.
so I finally have a solid fan solution. $34 CND vs $400+ CND
