My name is Hunter, im an equipment mechanic down in mobile al. I have a few questions about a 250r I got a little while back. If anyone could help me out I would appreciate it greatly.
Guy I got it from says the engine was built by norris Quinn.

What would you like to know?

Anything you can tell from the attached images. What parts you see, possibly who used to own it or built it, contact for norris Quinn so I can ask about the engine. Its a mean little feller but I hate not to know what's done to it.

Looks like you got a stock cylinder with a name written on it. Don't have any idea who he is or what he did. If you look real close to tell if you are using the .010" cr250r head gasket. If it is you will need to run race gas or you will fry the piston.

Not trying to come off as an ass, but you don't know who Norris Quinn is? From what I have researched and heard for years he is one of the guys that had a big hand in hot ridding r's all throughout the 80's and 90's. Do I need to mic the head gasket to see of its the one your talking about? Sorry im a diesel mechanic, been years since I messed with anything two stroke. Especially one that isn't stock.

Thanks to c-Leigh racing, rablack21, and scawn on the 250r.net I now have contact information for mr Quinn. Ill be giving him a call tomorrow and hopefully we can find out a little more about the history of the bike or atleast the internals of the engine.

No I don't and neither do you so I guess were equal there. Just trying to give you a heads up on a non stock gasket. Don't have to mic it either, you can see if its a stock gasket or not by the thickness. I am glad you got some history on your builder! But most of us run by seat of the pants experience. Chances are if you think you need to know the history you can pull the cylinder in less time than we are chating. c-Leigh racing, rablack21, are members here also. Good luck!

My problems with snagging it apart ore two things. First i wouldnt know what is and isn't oem parts. And second is Work and a 2 year old occupy most of my time. And id hate to tear into it and not be able to put it back together the same evening and leave it vulnerable to water and dirt or anything else that could manage to find its way in there while im not home. Can't wait to see what is found out tomorrow.

Check your compression. That helps determine if you need higher octane fuel for iit and if it may need a rebuild. Look at the head gasket as pumashine said, if it's super thin, Like maybe foil..? Then it's a cr gasket and needs higher octane fuel. If it's the thickness of a penny then your good with regular pump gas...use non-eth. Take that restrictive bent fuel line off, ditch the fuel filter and put a new fuel line then ride.

Hg looks like a standard thickness. Or atleast its about the same as what I run on a 2.5 merc outboard lol

What's this aluminum spacer looking device?

And here's the fuel line. Its a 3/8 line with a rock filter, you. Guys don't think it's a good idea to have a filter?

There is one OEM already in the tank. Don't remove that one without cleaning your tank first. But those little filters are restrictive. 1/4" ID

Welcome to the forum. I see...

Moose case saver
Fox front shocks. Looks 1st gen
Moose front bumper
Access skid plate
Moose nerf bars
Aluminum radiator shrouds
Anti-fade lock nut
Steering stem is aftermarket I don't know the make but I seen it before
Looks like you have a wrist wrestle on the stem
Your exhaust is aftermarket. Can't say for sure but I would say CT. And the silencer is mismatch

You have a long rod crank so the spacer is needed to align the ports.

Hope that helps some. Now go make them new tires old

Leager stem, Im sure a guy with a pro trax front end would love to have that.. And I dig the air cooled Atc!

Sounds like you got lots of good advice there Hunter. Norris Quinn is still involved in motosports and the 250R world. He still builds engines, 2 and 4 stroke, and builds shocks. I have been told that he still does Joe Byrd's shocks. He has been building and servicing my shocks for the last year and also sponsors our atv motocross series.
