    Manufacturing your own ht engine?

    My idea is to build my own engine. These bike engines are quite simple. Plan is build a foundry and cast the crankcase and tap the holes to 1/4 and maybe 5/16 instead of metric. I'll get a drill press and probably belt sander. I already have a grinder but it needs a new spindle and stone. Then...

    Miniature v8 or v6 on a bike?

    Time for another think tank on these ideas I have lol jk. But I saw a homemade 394cc v8 bike on youtube made by a guy named Dennis Franz.

    I've just been going through ideas I had after looking at a few old weedeaters, of course these engines are very small I wouldn't go under 25cc and pedalling would be neccesary. If you could attach a pulley to the shaft while still keeping the pull start then you could build a mount for the...

    Hey guys just want to talk about an idea I had. They make snowmobile engines that are multiple cylinder 2 strokes right?. What if you could scale one down and have an inline twin 2 stroke say 50cc so 2 25cc cylinders wouldn't that be cool? should rev really high too. Has anyone attempted to make...

    possible interesting idea.

    Although it would eliminate the use of pedals... i had a brief thought in my head involving two right hand crank arms from a vintage cotter pin style 3 piece crankset. Cut the crank arms off, leaving you with just the chainring. Throw those on right and left sides. Connect engine sprocket via...
