RE: NEW ENGINE IDEA!
splcrazy why 50cc? On DDM [link]http://www.davesmotors.com/c.885035/site/index.html[/link] they claim some serious hp from some of there engines at lower cc's. I don't have a baja but wouldn't it be hard to get it to hook up with to much power? Anyway Zenoah does have a 61.5cc engine
From DDM's support area for rc's also check the goped area there are more engines there. [link]http://www.davesmotors.com/c.885035/site/support.html[/link]
