Removing the upper section.
Then cut of the attachment to the lower section.
Along with removing the "seat section" the brackets that held on the foot pegs needed to be removed so that the 1" mechanical tube could fit over the lower seen in the above pic. The small tubes that form the cradle around the engine are 3/4" O.D., which is convenient since a 1" O.D. tube with 1/8" wall has an I.D. very nearly 3/4". I can now create a slip joint that will attach my hard tail section to the lower tubes. Pretty slick :>). Next we will begin to mock up the lower hardtail tube with cheap EMT from Home Depot to make sure we like the look before committing to the more expensive 1" mechanical tubing..
