Well This is the first Post On a long project.
I will be cleaning and repowering my Bensen B8-M I will give it some updated gauge and other equipment like fuel tank and so on.
But the Majority of the work will be concentrated on the proper installation of a Yamaha RX1 4 cylinder 1000cc I know some will say this will be
a bit too much power for the bensen and I will need to raise the throtle slowly so not to make the torque twist and roll but this will be gear to use the lower part or the rpm range
9000 rpm on take off and hoping for 7500 rpm on cruise i'm sure that it's possible to do with the weight of this machine.
I give my self a 3 year project for this but I'm mostly looking at 5 years and 5000$ investment.
But with this powertrain I will have a resent engine and not one from the 1940's
now give me pointers on that to look for and tell me if my setup makes sense like redrive gearing I will have about 120hp out of this 150hp engine.
installed weight of Continental A65 175lbs 65 hp
installed weight of Yamaha RX1 engine 165lbs 150hp but 120hp usable in my setup.
