Saturday we went riding at my friends farm and that evening i got on my quad and it cranked over very slowly like the battery was dead and it wouldnt start (it had only been sitting for 5min). So we pushed it and it started right up ran for 30 seconds and died. Tried pushing it again and it would just slide the tires even in 5th gear. I assumed the motor was locked up. I then hooked up jumper cables and it started again but was running horribly and died then nothing. Took it home hooked up the battery charger. Fully charged the starter just hums really loud. I pulled the clutch basket and all the bolt are still in place and it will roll fine in neutral. The motor has 7 cross country races and about 30 hours of riding, so probably low 40's total. I pulled the motor for the first time and am going to tear into it this weekend. Oh yeah and the engine oil and tranny oil had no shavings and didnt smell burnt. Any one have any clue what the problem could be?

Check your stator (not starter) wires, I had the same problem and was freaking out that the motor was bad. Fixed my connections and put a new battery in and it has been flawless.

Sounds like your decompression mechanism took a chit on ya. If you want, I'd take a look at it for you. I'm up in Pennsylvania. I'll be heading to Powhatan, VA this weekend for the group ride if it's near you, I can stop and pick your machine up.

Right now I am at college in Morgantown (5 miles from Pa) the bike is at my parents house in parsons 60 miles south. It definitely seems like something solid is stopping the whole engine from moving. But the problem did seem like it could be electrical at first, I just don??????????????????t see how a loose connection would make the engine seem locked up (I would be very happy if it was though).

That's no problem, I'll have room in the enclosed trailer for your machine if you want to work something out. I think it's the de-compression arm on the cam. That's what it sounds like. I've got parts here to fix it up, give us a call if you want to work something up.

I have the engine out already so I could maybe go get it Wednesday after class (or pop the side cover off, if it would be an easy problem to diagnose). I am pretty well broke now though, so I was really hoping to find out what is wrong now and fix it this winter. Also I haven??????????????????t done the stud update yet and was wondering if it would be necessary since nothing has came loose yet.

oh, okay. Well you'll have to remove the side cover, and then take off the valve cover. Once you get that apart, check with an engine manual to see if everything looks like it's in place. Once you have her apart, I'd do the stud update. Once you tear into her, give us a call, I should be able to tell you what to look for and help ya get her back up and runnin.

same exact thing happened to mine about 3 weeks ago. I am having local shop swap out motor and will take a look then. Let me know what you find out.

So if the decompression mechanism broke does that mean i will need a new exhaust cam? I just looked on Atk's list and it is $340 that seems very high to me for a cam. What other parts would i need? Just curious because there is no point tearing the motor apart until i can afford to fix it.

No, you won't have to replace the cam as long as it's not damaged.
