got a bargain honda vf750f it had been stood for 2 years, and it was very noisey (it started with new plugs and the right battery.) the front cam chain was loose and the front top oil pipe was the original 25 year old one which should have been recalled, the motor was as it left the factory at the front two cylinders! so ive been repairing what needs fixing and ordered a few new parts. also i made a special exhaust, its from the collector box into 2 pipes, which are roughly 3 inches in length straight through with 45 degree slash cut tips. not heard it run with them yet as im waiting for my cam chain tensior to arrive. watch this space.
