I have a 01 400ex. Just put Wiesco piston in it. New Timing chain and adjuster. Has a Hot cam stage 1 cam. I bought it pieces. Had the head off the quad with two bent intake valves. I replaced them with OEM valves. Lapped them in and put in new seals. Air snorkel was missing so I plugged it and pulled the air lid off and went up 3 jet sizes. Has stock exhaust. I know its rich but figured I'd dial it in once I had it running. It had no key either so I have a two way switch black wire on one side and the red wire on the other side. Key had 4 wires to it. This is how I got it to start. Also I am waiting on clutch cover gasket so I used 1211 Gasket maker to put the gasket on. So thats the down and dirty of everything I did.
I started the quad for the first time fired right up and ran for 10min. Onced it seem to get warm it shut off. I hit the start button fired right back up ran for about a min then shut off. Hit the start button again ran for a min and again shut off. So I left it sit. I was frustated.
Went back next day. Choked it and motor fired right up not even trying. Ran for the 10 min and again once motor seemed to get warm shut off. Fired right back up then ran for a min and shut off. Fired up again and shut off after a min. Exactly like the first time.
Each time it shuts off right before it dies it sounds like the motor gets dry or like a squeaking noise. from the left side.
This has been a rough project and I just want to ride. and I am becoming very stumped. Sorry for being so long I wanted to give as much detail as possible so I could get so help/
What could this be....
Is the oil pump..Causing no oil circulation and once it get hot it seizes.
Is it the starter.
I don't think it fuel issues because it idles and revs during the first 10 min with no issues.
I've triple checked timing, and its perfect.
I've triple checked valves.
Has new spark plug.
Has New battery.
Any help would be a blessing.
