We originally restored this bike for Ewan Mcgregor in 2010, The motor has been modified from a short stroke crank to a T3 long stroke crankshaft, and cylinder size has been increased from the stock 82.5mm to 88mm, So now its a 955cc. The bike was just in for service after a commercial production company Over Rev'd the motor and scarred the crankshaft and cylinder walls. She is all good now, Enjoy the Video and thanks for Watching.
