sounds like the floats are stuck or bad needle and seat try tapping on the bowl with a screwdriver handle this may work if not pull the carb and look inside

Wait newbie to bikes or to working on bikes? Cause newbie+cr500=disaster, but yeah sounds like your floats stuck as mentioned above, if its not stuck you need to set the float level.

Check your owners manual it will have proper float heights, if you dont have one order one or possibly you can post a thread asking if anyone has a downloadable one for that year cr 500.

Float adjustment here:

If the bike is sitting upright and fuel is overflowing there is only ONE cause and it is float related.

The float is allowing fuel to flow out of the carb.

Either the float is cracked or stuck or the float needle or seat is bad, or the float is not adjusted properly or some other float problem.

The float level specification is 16mm on the 1989 CR250.

I had a 89 CR250 that would drip fuel when on a side stand. The fuel petcock was bad and would let fuel continually drip by even when the fuel was set to the "off" position.

Do check the fuel petcock, if it leaks it will send fuel to the carb and overflow the float.

Set fuel petcock to "off" remove fuel line, let bike sit for a couple of hours, if fuel has dripped out that will also overflow the carb. Buy new fuel petcock and "O" ring and install if fuel drip out of petcock.
