Default Re: Making a custom bike engine

A flat 6 would really be cool... Something like this... with 2 extra cylinders... ... That would be a 288cc engine if you use the 48cc jugs, or a 396cc with the 66cc jugs on the typical 40mm stroke... That could Easily make about 50hp or more if designed really well...
