Rough idle.

I stacked my rmz 450 a couple weeks ago. Finally fixed everything but when I started it up I felt it was idling high and also rough. It went untouched for three weeks. Could it be old fuel or something more serous. I haven't taken it for a ride yet. Also there is oil on one of the forks. Can I fix the fork leak myself? Help me I'm a noob!!!!

Fork seals are pretty easy to replace... check out youtube and you will see exactly what you need to do.


As for the rough idle... check all your connections (pull them apart, spray with contact cleaner and reconnect). My guess is that one is loose.
