1982XR250R

Recommended Posts

Finally got a good insulator and cleaned the carb jets etc. put it together and nothing. I tried the screw at 1 then 2 then 3 turns out but I was lucky to get a weak backfire. Fuel is running good, spark is strong. Anyone know of some special quirk this might have? Anyone know how many turns on the screw for this machine?

Replace the pilot jet with a new one, and clear the passage above it with fishing line and spray brake cleaner.

I did clean it out with a welding tip set blew carb cleaner and about 60lbs of air not good enough? I do appreciate your response and will give that Area another look. Anyone out there have a PDF maual for this bike I can give you $10.00 paypal for your trouble thanks

 Start with one turn out.

Start the bike, and lower the idle as low as you can get it.

Not raise the idle using the fuel screw.

Your goal is approx 1.5 turns out, but the idle speed is most important.

If you need to go much more or much less, that means you pilot size is off.

 

 You can't clean the corrosion out of the inside of a pilot jet.

Ok thanks I will get a new pilot jet thank you all all for your advise! At this point I cant start it but once I get a pilot jet hopefully it will and I will adjust 1.5 out thanks again!

thank you!

Well I purchased a rebuild kit and in this kit the pilot jet is a screw in. On the carb the pilot jet is a push in. Can someone tell me what I'm missing here?

Looks like you have to clean the old and press it home, or make the new one fit.
