Guday mate.........I know this post is old, butI can't sleep and this is interesting stuff..
Boy, what you have to go through down there to ride on three.......
Have you had any luck getting that COG point on your HD?
I would love to watch you guys balance that bike on its rear wheel.
If you haven't got it yet let me know. Seeing as I have an06 Fatboy that I have triked and it doesn't have fenders on it. I might be able to ge a few friends and stand her up.. and get that COG for ya.......My rear axle is 46" wide.
Let me know.......
