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.

I know...I feel stupid for asking. I find it impossible to use the thumb throttle with my thumb when I have the bars turned full right. I have to reach across the top and grab the throttle from the front with my fingers. It isn't very smooth and I can't help but think that there must be a technique, mod or adjustment for this. How do I get past this?

My 1990s KLF 300 has just developed this problem where if I turn onto full lock in either direction, the motor cuts out. It suggests to me either a short associated with the ignition switch, or more likely tension on a wire which is losing contact when pulled. To me this seems more likely because I would expect a short to show up as a flicker in the ignition light, which it does not.
Before I strip it all down, has anyone experienced this, or could you advise me which wire/s to follow? Even though first look shows a number of wires in that are, I guess only one, or two would be involved. Thanks in advance.

The Hop-Up: You may be saying to yourself, “that’s a chick bike,” and you’re right. But honestly, it’s so much more than that. It’s one badass bike. http://www.quadmagazine.com/quad/features/article/0,24942,1587044,00.html
Hi all, I try to find this manual in the threads but you have a lot of stock here
Cannot find this particular manual.
I found it for YFM200 but not sure if they are the same.
Thanks if you could help me with that.
Im new here so if I did something wrong, please tell me.
Hey I own stock why Yfz 450 and I'm just looking to slap a turbocharger on it.. I was just wondering if they're pretty compatible with these machines it is the carburetored version Yfz 450. I have all the piping hook ups / kit that's threw HURON SPEED an i also have turbo lined up for it gt 12.. I was just wondering what else I need to make this work? I know i would need to up the Jets and stuff for starter but Is it just that simple or do I need blow off valves and like some time on regulator on it or so forth? Trying get ideal what i would need
This is my first post and I was wondering if there is anyone who can help me solve a problem I have with my Yamaha Kodiak 400 4x4 Fitted with a Mikuni Carburetor . The year of the quad is around 1998, the reason I am not sure of the date is, there wasn't any paperwork and no details on the frame either.
The quad had a bad leak from the carb overflow which indicated that the float needle valve was blocked or passing so I replaced this and put everything back together. The quad ran really well until I took it onto some rough ground to have a ride around, a few hours later the engine started to run really rough as if the engine was flooding. I have removed the carb again and cleaned the needle valve out and the whole of the carb just in case there where any dirt behind it. Engine now runs fine again but fuel has started to run out the carb overflow again.
I have tried everything to try and stop the fuel leaking out the overflow but its still happening. My last thoughts where to adjust the float level and its still happening.
Has anyone got any thoughts on the problem or could suggest whats causing the fuel leaking out the overflow.
Thanks for reading
