I saw this the other day and instantly wondered how bad my CT70 frame/chassis would twist with something like this bolted up. The thought was silly enough to put a grin on my face so I figured I'd post it. Hopefully this is in the correct section. I'm actually not sure if it's a 150 or 250? Could be a 450 for all I know. Maybe someone here might know? There's a couple guys building some pretty crazy motors in the Philippines(I think). They either add a cylinder or mix and match Top and Bottom ends from different years, different models or even completely different manufactures. They re-engineer the hell out of thier motors using SUPER basic equipment. I've seen a few videos of running motors and they actually sounded pretty good. I have a hard time imagining any of them running for very long and wouldn't doubt it if they blew up immediately after the videos were taken!lol Maybe they'll run forever. I've seen guys in Australia reconfigure the bajeezus out of a few different motors and thiers are reliable. They do use more modern/hi-tech tools to build their motors though.
