I just got my 96 speedster last year. This year I lost oil injection in one cylinder. Im in the process of fix my cylinder wall. I spoke with a mech on going to an oil mix in the gas. He said that I need to keep the oil reserve and two lines coming and going from both engines. I will know more when I get in to it. But It is supposed to do with the main crank of the engine and keeping an oil sump in there or something. I'll keep you posted.
