So I bought a 2001 Quad Runner 250 for my son/wife. Sorry I run a Grizzly 660.
I’ve rode it many times with no issue.
My son’s first time out, I could always hear him but feeling he ran it red line in first gear a lot.
So this is what it was doing during/end of the 2-3 hour ride:
- halfway though noticed smoke (oil) coming from front of the motor sort of under exhaust manifold. Once back at the truck, it was really noticeable. Definitely oil burning off. I’m thinking from the top end maybe.
So quick inspection:
- No leaks or seepage of oil that I could see
- I pulled the plug and it’s black but not wet
- No blue/white smoke in exhaust
- seems to still ride fine
- Engine still has plenty of oil
But now that I’m looking at it back at the house - it’s a hard/won’t start when hot. It starts right up cold no problem but once it stalls when hot, have to let it sit for 10-15 before it will start again.
It wasn’t idling before that trip so I jacked up the idle a bit as well but I think that’s a carb clean/adjustment but...
Any input is appreciated.
Thanks for any help.

Hello Guys, I'm new to the site, but have been reading about all the issues that I to have had with my quad. I have rebuilt the carb a few times, once when I got it a few years ago and again a few weeks ago. Same problem, it cranks fine and idles well but when I take off it stumbles. After looking at the site I saw all the posts about the rectifier/regulator so I grabbed one off eBay which came today. Once I found out where it went I saw that the original one wasn't there so I have no reference however I mounted it and began to connect it but one the plugs doesn't fit. The red/black plug connected fine but the yellow wire plug doesn't, and I don't see any other plugs available. Apparently the guy I bought it from had removed the original regulator and it wasn't with the ATV so I have no idea what it looks like. I will also say that I was surprised that it didn't have a rectifier on it but cranked and ran fine till the stumble. My question is, do those yellow wires have to be hooked up ? And my apologies for the rambling, I'm doing this on a phone and can't see the screen. Hahaha

Just got an 86 TRX 250, not running for past 5 years.
Currently with battery hooked up there no power. I checked the fuses. Will go meter the off/run/off switch and ignition switch tonight.
I'm, looking for a decent wiring diagram or a copy of the service manual or ohm specs for coils/stators. Any help would be greatly appreciated.
