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.

x just bought this expedition 425 and the Speedo needle does not work. The lights work for the shift indcator. So is this an electronic Speedo or cable? Is there a way to fix it or will I have to replace the unit? Thanks for any help you can provide.

I need to figure out how to clean/fix or replace my neutral switch assembly On my 2008 Yamaha big bear 400 as generally the neutral light doesn’t come on when it is in neutral. To get it to come on I have to wiggle the foot shifter and hold it in just the right spot.
I have googled it and can’t find much on the 400’s. I can’t find a service manual online and the parts manual is super vague.
I think it is in the right side engine cover area, but not certain.
Any help would be great. thanks

I replaced the fuel pump filter and it ran great for a week or so. Then while driving across the yard in 3rd gear it shut off and hasn't started since. It has fire and its getting fuel, all fuses are good, battery fully charged. The fuel pump relay seems to be warmer than it should be when spinning it over. Any help is appreciated!

Ok...I'm gettin' me juevos ready to do an oir filter clean....
Went to my local harley/quad dealer and he had me purchase the No-Toil kit (Cleaner, Air Filter Oil, Rim Grease)
What I've read is that the No-Toil cleaner will NOT clean
other oils off air filters....just the No-Toil oil....
So, I've also read that others have cleaned their air filters
in the kitchen sink, used gasoline, or used flash solvent....
Looking for advice as I've mentioned I'm very mechanically
I'm going to wash the air box seal in the sink and give it a good dry....
One more thing......No-Toil or Bel-Ray for filter oil?
Has anyone found engine oil in their air filter box. The must be little or no baffle between crankcase ventilation and that hose that attaches to the air filter box.
I went to pick up my ATV today 60 miles away that they could not fix the jerky low speeds on and before I loaded it decided to check on this. Sure enough there was a good coating of oil with some pooling in the bottom of the air filter box. The air filter has oil on it too but is it a dry element or oiled element type. My guess from the color of it dry.
I heard on a comment on my YT videos that there is a kit for this issue? Is this a CFMOTO fix?
