Hey Paul, sorry I don't check this like I should, I will get you themeasurement this weekend. If i had it to do over again I would lower that front hole 1/2" from where I have it I think then I would get the wheelies on max transfer, right now on max trasnfer I get about 6" of lift and i have to work to get that, its perfect but there aint no more. On full ski pressure i can do figure 8's on the bare concrete!
Side effect if this lowers the skid slightly over jack shafts set up and raises the Center of gravity slightly but its worth it to me to have the rear bolt UNDER the runnign board, also gives a little more clearance for studs.
