    Great post!

    Maybe this should be in the FAQ section for all of the new folks.

    Thanks again!

    Great post. The only thing I did different is that I didn't take the gas tank off. Just the straps. Then I lifted it and slid the throttle cable out from under it. Might save a little time.
