*5.5hp honda engine with governor on a go kart*?
I have a 5.5 hp honda engine on a co kart and want to tweek it out a little. I have found aftermarket kits available for this engine that consist of different cam, head, intake, exhaust, carb and springs. Stock the engine spec is 3600rpm. One of the kits say 6000rpm. I'm wondering how they plan on running 6000 out of this engine without removing the governor. They show everything in the kit in the picture and it has no linkage for modifying the governor. I have no problem with bypassing the governor but I have heard alot of rumors that it will blow up the engine. I'm going to school for motorcycle mechanics and my instructor thinks the governor is only there for epa reasons so unless you have physically saw a motor like mine blow up dont just answer off rumor. It is an overhead valve engine so I would imagine it would float the valves before blowing the engine but I want to be sure.
The governor is there partly for EPA and also to control the engine under "normal" conditions, e.g. to allow load to be picked up when used in a lawnmower. You can safely bypass it, provided that you realize that this will take away a safety option of not allowing the engine to over rev. But as you really want to over rev it, what the heck! Obviously as a go kart engine a governor is a damned good definition of a useless motor!
