i own a 2006 crf100f and the spark plug was replaced last week. but now the idle just keeps going up and up even after turning it down
maybe 10 times during a 5 hour ride anyideas?

Here are a couple quick things to check.
Throttle cable where it enters the carb top also listen for the carb slide has you snap the throttle.
Air leaks - around rubber boot from carb to cylinder.
Rubber vent tubes on carb body for obstructions.

Hope those give you some direction to go searching.
