[QUOTE="5BrothersFabrication, post: 214089, member: 2617"] My 7 year old son Cory is building this Yerf Dog, after he grenaded the Tecumseh 6.5 that was in it. We figured we'd find something they still made parts for so I went to Cycle One in Knoxville and dropped a buck or a hundred and fifty and came out with a nearly-complete Honad XR80 motor. Took her home and found out quickly it wouldn't be a simple bolt-in. With the motor all the way against the seat, the bike sprocket sat 1/2" in front of the axle centerline. So I started hacking the frame to stretch the wheelbase and drop the eng sprocket low enough not to eat up the case with the chain. By the way, I still have to do all the welding, he's not a fan of spatter burns. [IMG]http://i1154.photobucket.com/albums/p526/5bros/2012-02-23192737.jpg?t=1330043310[/IMG] Wasn't gonna work. [IMG]http://i1154.photobucket.com/albums/p526/5bros/2012-02-25162233.jpg?t=1330205490[/IMG] Easiest way to remove the frame. [IMG]http://i1154.photobucket.com/albums/p526/5bros/2012-02-25162241.jpg?t=1330205550[/IMG] Removed the bar that mounts the frame to the rest of the buggy.

[IMG]http://i1154.photobucket.com/albums/p526/5bros/2012-02-27211836.jpg?t=1330395550[/IMG] Put in the crossmember for the engine mounts and gusseted the heck out of 'er. [IMG]http://i1154.photobucket.com/albums/p526/5bros/2012-02-27211916.jpg?t=1330395767[/IMG] Another angle.
