1998 Blaster Starts, no idle.

[skillet]

First, I'd like to say that I'm trying to grasp the concept of posting certain questions in their proper sections.

Second, specs on the bike.

1998 Yamaha Blaster
Big Bore Kit
Oil Injection Block-Off

It starts fine, but will not idle. It was fine and peachy two nights ago. I picked it up tonight and she starts, but wont idle... What changed over the course of two nights... Hes been mixing 60:1 which is incredibly lean, and the tank is full.

My diagnosis is: Plug is fouled/burned up.

Should I

A) Check and replace plug.
B) Drain tank, check and replace plug, refill tank with my own Pre-Mix, 93 Octane w/ Spectro Synthetic 40:1
C) Anything else for the good of God's people?

Can you keep it running after you start it, by giving it a little gas?
If so, How well does it run? Does it rev fine? Is there anything out of the ordinary? If it was a fouled plug i would assume it wouldnt start...
