Just lookin thru your pics trying to pick up details. Can you clarify & made any suggestions?
Cool that you were able to mod the stock engine bracket to work with the twin. And great pics of how you did it.
Looks like you opted to run the stock Marathon generator/alternator? So the output shaft on the engine needs to be long enough for both the clutch & the generator belt pulley? I know some of the engines out there have alternators in them, some low output, some not. Is your method more reliable? Any idea if there is any significant HP loss?
And stock muffler, modified exhaust pipe?
What did you do for the air intake?
Any video of it running? Times? Speeds?
Good stuff. I've thought about doing just this with one of the Honda Clones in my Marathon.
