1983 250R Seized Yesterday!!

[drhill]

Lean...hmmm...the guy I bought it from had it sitting for quite a while, cleaned the carb and got it running...seemed like it was running really well. MAYBE...just maybe, he didn't get one of the smaller circuits cleaned all the way and the low speed riding just burned it up...I was ripping on it pretty good up until them (for a few hours) and no problems...

Does that sound like a possibility?

Carb kit sounds like a good idea...I'll get the jug off and pull the carb apart to see what jets are in it and overall condition...

be sure to tell us what position the clip on the needle was on. They always run best right before the blow!

[harryredtrike]

stock runs 20-1,most people are around 32-1.

I ran 40:1 on my 84 for 2 years. Never any problems!!

Here's a link to an online manual for the air cooled 250R's. It might prove to be very helpful to you. Good luck!

DRHILL, I think all this led to your problems. If I were you, I would definately switch to a 32:1 mixture, and then set my carb to stock settings which is a 130 main and the needle in the 3rd position down. You also need to stop at first opportunity and clean cakes of mudd off the cylinder. Letting is sit on there will make it heat up much faster and run hotter. Also check around your reedcage and carb for air leaks.

man that guy was a pansy, he was scared to open er up, and it seized. Man if someone drove my wheeler to slow and it seized I would be like wtf man pin er!!!

Your problem sounds similar to the time I melted mine. My main jet was fine since I usually cracked wide open often. One day I decided to make a half throttle cruise and the jetting wasn't at all right for that. I'm betting you were lean.

Thats Really lean man...........Ol Deuce

tha would be AIR FOOLERS , but all one word

[drhill]

air foolers huh? I've heard of that site...I'll visit! Gotta get the jug off tomorow and order up the carb kit and, piston kit and gaskets...oh yeah...and a torque wrench!

[drhill]

Took the jug off tonight and pulled apart the carb a bit...just like some suggested - Small jet was clogged..also it was a 48, I think stock should be a 50? Anyway - getting a carb kit to make sure this thing is right. The top of the piston is actually burned off on the exhaust side! Also - I can't get the pin out of the piston...I got both clips out but the one on the side that got hot was a real pain...Is there a good way to get this thing out w/o damaging the rod or crank?

[drhill]

OK - got the pin out of the piston by using a socket and a c clamp...but I noticed small metal shavings and pieces on the crank and some in the oil as I spin the the crank around...is there any way to clean this stuff out without having to tear into the bottom end? I'm sure they are peices of piston and clylinder wall that came apart...
