40-0493Replica black TT Bobber rigid frame oil tank is 1-5/16" shorter to accommodate a raised position for chain alignment.NOTE: Purpose of this tank is to raise the transmission and clutch pak for TT racing or hillclimbing for greater ground clearance. Battery compartment is shorter in this tank so a smaller battery will be required. Chain guard will be in a raised position so modifications must be made to the front mounting tab as most TT bikes did not use a chain guard in the early racing era. Oil tank front mount must be removed and rewelded in place 1.25" upward. To raise the transmission mount plate use (5) 1-5/16" spacers and mount as stock. This will require (2) 3/8"-24 UNF x 3" bolts and (2) 3/8"-24 UNF x 2-1/2" bolts for the transmission plate
