I am putting a Tecumseh series 1585a engine from a Toro S200 snow blower onto my tandem bike. As best as I can find, it's an 85 cc 3hp 2 stroke motor.
The bike, loaded for touring, will be heavy. Including my 200 lbs, the bike, and the gear I plan to travel with, I expect a total weight of 425 lbs. So I need the horsepower, especially since I intend on using the engine to help me up the mountains in KY and TN! My goal is for 30mph on a flat road with power to spare for hills and such.
I have not pulled the head yet to see, but I expect to mill the head (or block if thats the design) to raise the compression. It is a pull start and will have a centrifugal clutch, so starting is not an issue. I will have a servo motor hooked to the engine as a generator to recharge a small 12v battery so I can keep the lights, gps, cell, and laptop charged as needed.
My big question is, what can I do to quiet the thing down! I do have a bit of reserve hp, so a muffler that quites really good at the expense of some hp is ok with me. I know a 2 stroke will never match the quietness of a 4, but there has to be some options for me.
And, once I have some nice quiet muffler on, what are some tricks I can use to regain some of the lost power?
Thanks
