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!

This is exactly what me and my son do and its a blast. I would not be surprised of you spray them rings down good with starting fluid and clean the ring grooves on the piston, put them back on and take a company reading again and see what you get. My guess is you will be impressed. The cam journals look good, it all looks like it needs one hell of a parts wash.

Ya, that's what I thought. I need to get it running in order to check out the drivetrain. I pulled the top end off, the cylinder is ugly but not scored or scratched at all, no pitting. The reason for the low compression is that the compression rings are stuck. If I thought the gaskets would seal again I might just loosen up the rings and put it back together just to finish checking things out. The piston is in good shape as well, timing chain was nice and tight. It's got 2800 miles on it, not too bad for it's age. I think I can do a quick hone on the jug, order rings and gaskets and put it back together, assuming I can change the cam and rocker later (it looks like I can do that without removing the head, correct me if I'm wrong). The plastics are ok, they've got hairline cracks like they're real brittle but mostly in tact, one of the rear fenders has a crack around the rack mount hole but not too bad. Ya, that's the best deal I've seen so far, I've been buying these for a couple of months now just for something for me and my son to do, they're fun to work on and more fun to ride. I paid $500 for a '95 bayou 220 and an '02 Honda 300ex last month, the Bayou needed a carb cleaning and the muffler reattached, the Honda needed a CDI - that's it. We've been riding them on the weekends and having a blast. I bought another Bayou 220 for $400 that was really clean but had a broken shift lever, I fixed that but it also has a knock I'm trying to track down, and in the middle of that I lost spark (thanks for the help on that BTW). I also bought an '06 Bayou 250 for $200 that's had a rough life, I'm putting the top end on that as we speak (thanks for the help on that one too). It's always nice to find a real clean one, this Suzuki is certainly not. I've been looking for a 4X4 for while though and I couldn't pass this one up.

I used to view common sense as a super power. After years of dealing with people that don't have it, I realize it's actually a curse. Ignorance is bliss after all!

$40 bucks??? And @Ajmboy says I find all the deals lol. listen if the plastics are good and the atv is in tact for the most part then yes $500 would be worthwhile. It would sell for $1000 to $900 in good running condition. The plastics and parts would be worth about $600 plus if you just want to part it out and thats a minimum estimate. If you think you could get that atv back to good for $500 then do it but make sure your not wrong and check all the gears and differentials as well. Be a shame if you did all that just to find out there is a drive train problem.

Great work! Make sure you add grease to the cam lobes prior to start up and your timing is correct. New valve seals as well I'm assuming?

Something to bear in mind: if the adjustment screw is on the engine side of the carb (like this one) it is a fuel screw, so turning it out richens the mixture. Most 4 stroke carbs are this way. If it's on the airbox side, it is an air screw - common on 2 strokes. This works opposite but really does the same thing. It just fine tunes the pilot (slow jet) circuit in all cases.

If I printed my own money I would not be trillions of dollars in debt

Just not long got this wee gem . 2004 ltf300 King quad. With under 2500 kms from new. Hunting wagon and general work around the lifestyle block
