Honda Z50J Monkey gallery It’s me: the 6 feet 4 Monkey dude. Yes, this does not make any sense and I like it! Honda Z50J Monkey, standing between giants during testing, customs and registration, RDW test centre, Amsterdam | September 2010 An old 1970 Range Rover easily takes two minibikes. But… with a little effort, you can take your Monkey bike in a Smart for two aswell! Genuine Honda 49cc ∅39mm cilinder, bored three times to get ∅44mm, for a spectacular displacement of nearby 65cc ;-) The piston-man is checking out the new old stock S65 gaskets. Touched for the very first time. Genuine Honda S65 cilinder head to match the S65 piston and over bored cilinder. Genuine Honda S65 inlet prepared for the future! At the moment I am still breaking in the engine with the standard tiny carburettor. Watch out when greasing! (or when brushing teeth, priorities…) Heat resistent engine paint cooking. Kitchen windows open please!
