Hi all! I am new and I am about to embark on my first building experience! I have been reading about the 2 stroke vs 4 stroke and have decided to go for the 4 stroke. I hear its quieter which is good for me since I will be riding it to class and don't want to be THAT person who rides the loud bike and makes everyone look over their shoulder. I also don't really want to deal with mixing the gas and the oil. Lastly, I have heard that the 4 stroke gets a little more power and lets face it, I'm not the smallest twig on the bush :/ Please comment if anything here is wrong or if important info is missing! I am unsure as to whether my current bike will work out. I'm pretty sure I won't be able to mount the motor on the down tube. I don't know if it would work on the top tube though. I've attached a picture of a bike similar to mine. I'd post an actual picture but at the moment it is dark and people usually are gathered outside acting crazy (gotta love college life!). Also, it is difficult enough to type with my chest spasms I'm experiencing today, so I don't know if I could actually pick up my arm to click the camera! I know there are rear-mounting kits, but I'm not sure I like the way those look and my bookbag would probably get in the way. If I have to, I can get a new bike, but it'll have to be a cheaper one. I'm considering selling my guitar I never play to make up some money to do this project, so it goes without saying that I'm a college student and I don't have a fortune to spend! Any help or comments would appreciated! Also, if you think it'd work to mount the motor and such onthe top tube, please post some pictures so I can see how it looks. Thus far, I haven't found too many of them (which in part leads me to believe it is a practice frowned upon by the bicycling community). I'm a bit overwhelmed and confused and tired of reading stuff I really only partly understand, so please help me! Sorry its a bit long!
