Yamaha G2 Vs. Ninja 750 Motor
Hi All,
I have recently been invited to build a golf cart for our local Golf Cart Chuckwagon races. (ill let your imaginations wander) I have found an inexpensive Ninja 750 engine that I was planning on throwing in it. Has anyone done a swap like this? its an old electric cart, so Im not exactly sure how I could marry the engine to the final drive. I was thinking of keeping the differential, for when im taking it easy on the cart, but im not sure if a straight axle would be better? If i was to use the stock rear, how would a guy get connected? Thanks! |

Re: Yamaha G2 Vs. Ninja 750 Motor
That's a big (dimensionally) motor. A solid axle is the way to go. No reverse, but if electric cart, no reverse anyway. The "locked" axle won't stop you from turning.
The orig rear is too complicated to dink with. Be sure and get all electronics off the donor scoot. If old ZX, some electronics could be hard to find and expensive. Very little I overlap for electricals. None for the main harness. Some older Kaw street bikes had matched anti-theft key switch. No fire without the match. You can do a work around but it's tedious. Before beginning your project, get the engine running properly. Those things are famous for bad intake valves, and bad carbs. Ideally you'll want the complete donor for exhaust, meters, radiator...ad infinitum. If the engine is fi, get the fuel tank and fuel pump. May not be useful if sitting for years. Aftermarket fuel pump can be adapted. The fuel pump isn't an issue with carbs. Any cheap low pressure pump will work with carbs. Any large live axle ATV rear assembly can be scabbed on May I ask what year scoot you're working with? Sent from my SM-G965U using Tapatalk |

MOST of them end up in the scrap yard, #1 finish it, #2 do it with safety in mind, #3 try not to die trying. Yes, I can say this, I've done it.

Re: Yamaha G2 Vs. Ninja 750 Motor
I'm going to offer a plan here. This is step one...more or less. The ZX750 would make a good cart engine. ZX750 was outclassed by CBR and GSXRs, and later ZX600. But it was an interesting ride with tons of torque. Didn't have to "stir" it constantly. Have to set the motor on blocks and calculate how much lift the cart will need to accomadate the engine height. Seat's gotta close. Easier to jack it up than cover up a high engine. IMHO.
WTH is a "Chuckwagon" cart. Sent from my SM-T560NU using Tapatalk |
