Ok i want to do a rack mount , here we go . I want to try to make a motorised bicycle out of my leaf blower engine. it is a 4 stroke engine. runs perfect. It is big leaf blower it is one of those that has a back pack on it it. I was told it is almost 40cc. So i know it will work for a bike. The only problem that i run across is me being new to this kinda stuff but i'm sure it needs some kind of gearbox. Because when i start it ,the propeller is moving way to fast to be on a direct sprocket, so i'm sure that would not make the engine run being so much of a slow revolution on a direct sprocket. I was wondering if i would need a gearbox and how do the gearboxes work. My only conclusion of a gearbox is the more throttle you give it the more the friction plate connects with the gears. Is that what a gearbox is used for?????. Do i Need a gear box??? And can i use this one on ebay?? http://cgi.ebay.com/4-Stroke-SkyFir...ryZ11332QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
