The regular 47 has a small walbro carb versus the 47R that came with a HDA large carb and a expansion pipe. You can still buy the HDA carb and expasion pipe separately or as a kit to HI-Perf the stock 47 (wich would give you a 47R type perfornmance) What are you mounting this beast of an engine to anyway???
Holy #$%@ man i thought 1 was kinda radical !!!!
reminds me of tim the tool man MORE POWER !!!!!!
your going to end up getting the same milege as a H-2 !!!!
But man the chicks will dig it !!!
Holy Cow 5-7Heaven !!! Man, why don't you just skip all the small engines and stick a 650cc V-twin in the frame and be done with it !!! (LOL) Good Luck and keep it safe.
Hawaii Ed would probably agree with me that an MB needs power and speed to safely ride the streets of Honolulu.
Reliability is important too, when you run twin engines. My pair of Mitsubishi engines NEVER needed attention. Tanaka motors should be just as dependable.
POWER! Did I mention that I had a 200hp six-cylinder Corvair engine in my 1955 Volkswagen bug?
