85 Trail boss 250 stalling
Hello all, I am new here so HOWDY! Anyways, my trail boss I just picked up is giving me issues. First off its a bear to get started. When you do get it running it flat will not idle, you have to keep feathering the gas and it has to stay full choke to run. If you release the choke even at high throttle the bike stubbles and will flat die like it ran out of fuel. I pulled down the carb and cleaned it really well so all the jets are dead clean, and the carb boot is in good shape. Also it is really loud. It has a clanging sound like the heat shield on the exhaust is rattling. But its internal someplace. Thats the best I can describe. Compared to my 03 trailfire its at least 3 times as loud. Anyways, if anyone cares to help me out in the guessing game or were to start it would help. Thanks, Ray

Boreable cylinder,but if needs a new rod then you need a press,truing stand and dial indicator to true crank(shop job) Seals and crank bearings(2 bearings on clutch side,one on stator side and seals can be done at home.

Crank Seals - Both of them !
Hi rayzors85
I went thru the same thing you are doing I think, follow my Posting, you will see waht I did.
I'm not an expert but I did change Both Crank Seals and my 1986 Traol Boss 250 starts up like it's new at the Touch of the Starter button - when it's cold.
