Hi...I like the idea about taking our time. Also I sold my motorcycle and
cleared out a nice big area in my garage. I have the batteries on the right
side near the garage door so they are out of the way. I would be willing to
invest in some good stands and other equipment that will make it easier. How
about we meet at my garage sometime on Sunday and forge a plan and figure
the best way to proceed. What would be a good time for those that could make
it?
I could also start to procure a few things Friday and Sat. if we thought
we would actually drop it on Sunday. Thoughts? Witt
