i was riding on sunday with my 2000 rm125 for about 3-4 hours on long trails and i went to go hit a pit up today and my bike wont run. i started it up cold and then i go to take off and the engine just dies. i pulled off the air filter to see if it was that and it didnt help, the engine did start a couple times but then the second you gave it gas it would cut out. So I pulled off the plug and it was fouled. cleaned it and aired out the cylinder and it still didn't start. Checked for a spark and that seems to be ok. So then i noticed sludge building up at the muffler. would this be a float problem? the plug fouled every time.
