I just bought a KingQuad and it seems I am the third owner. The guy I got it from said it was a 2008, 400. When I first looked at it I could tell the machine had, had a pretty rough life. The plastics were all wire tied together and a lot of it was missing all together. I wasn't to worried about the plastic, that is until I checked the prices on that stuff.LOL I was more worried about the nuts and bolts than the plastic. Actually the bike was in pretty good shape mechanically and I could tell the original owner, although he ran the pure living crap out of it he did replace stuff when it broke. I could see that all the CV shafts had been replaced and both drive shafts had new boots on them. The suspention was all tight and according to the guy I bought it from the guy told him that he had gone through the motor. I drove it around his yard and everything worked but the brakes, there was none at all, but it had plenty of pep and no smoke so I pulled out 28 hunnard dollar bills and waved them before his eyes and he forgot all about the $3200.00 he was asking and away I went.
He gave me a box of parts the guy gave him that had a new CV shaft, a tie rod shaft, a oil filter and two sets of brake pads which was a plus. Oh and I also liked the fairly new wheels and mud tires that were on it. When I got home the first thing I did was to make a list of some things I wanted to replace. I especially didn't like the front fender and the side plastic pieces and also I wanted to get a service manual. I got on line and found a 2008 400 manual and I bought it for $22.00. AS soon as I downloaded the manual I knew something was wrong. First was the rear brakes. The 400's had brake shoe's and this bike has that newer brake system that's on the front of the rear differential. Also there was no FI on the 08 400 So I got to looking some more and I saw that there was a 450 that was a limited addition that year which had that braking system so I ordered one of those.
Once I downloaded that one I could see there were more things that were different so I'm back to square one. Then I decided to try and find the serial no, which I probably should have done to start with but you know how it is. The guy I got it from said he didn't use it but a couple times to pull deer out of the woods but where he was at there was some of the worst mud I have ever seen......Oh did I mention that he said he never did anything to it but put gas in it, that I truly believe. I took it out side and started to get the mud off so I could find the serial number. Three hours later of scraping, brushing and finally pressure washing the frame I could see paint. The number wasn't where I was told it would be and another hour gone with a magnafying glass I finally found the number. It was close to where it was supposed to be but I couldn't see it. I finally took a tooth brush and rubbed the area and finally I found it.
Did I mention that before that a nice guy over on another site told me it might be a 500 because they did have a 500 FI in 08 so I got one of those too but it too was off a little. Well I wrote the number down an went in to do a search and the first one came up serial not found. The next one the same thing so back out to look again and what I looked at was right so back to the house to try again. The third check came back a 2011 500 x something. I tried several more search sites and they all came up with the same thing. Now the next thing that I'm wondering and probably worries me the most........How in the hell could someone rebuild an engine that was supposed to be a 400 when it's actually a 500.
I checked the air filter and that was one of the first things that I found strange. The 400's had a front mounted foam filter and this one was top mounted. When I finally found it it looked to me that it had never been cleaned lor replaced I guess everybody was looking for a foam filter and never looked in the filter box on top. I ordered a K&N filter but that thing don't seem to fit right. when the filter screw is all the way tight there is a small gap at the top and the filter can be moved side to side and you can grab it on top and the whole thing will turn. Let's see three service manuals and a $60..00 air filter and I still don't have anything, what have I done?
