Re: Yamaha G2 Vs. Ninja 750 Motor
I have lots. 2005 Honda CBR 1000RR, Mini Sprint rear axle, wilwood brakes, final sprocket count was 16 tooth front and 63 tooth rear. 10 inch slicks hooked so good had to got big with the gear ratio, ran 8.12 in the 1/8th mile @ 87 MPH. I did try to top speed the cart but at 115 MPH I said no more, my friend in the truck behind me said it looked like it was getting light, felt like it too. I chalk that up as one of my most stupid tricks

Re: Yamaha G2 Vs. Ninja 750 Motor
Rear axle is mounted on a swing arm, I did not have any IRS at the time.

Re: Yamaha G2 Vs. Ninja 750 Motor
WAAY too cool Rifter! Midget racer in a a golf cart costume...
And this is what happens when it the crap just won't fit...just cover it up with a conestoga chow wagon...chuckwagon. or a utility box. I'd go for length and maX width considering what you're doing in the chuckwagon race thingy. Of course there's them "rules"...I once built a "bathtub" racer. Found out these guys were serious about winning. I ran a bit to warm things up and ended up disqualified after a couple heats. I was within their rules, but my hand modified prop got me. Said it wasn't a stock motor. Well. That's BS. It was. Buttholes.. Sent from my SM-G965U using Tapatalk |

Re: Yamaha G2 Vs. Ninja 750 Motor
Wicked projects guys. Still haven't had time to do any work on it with work and trying to get the garage ready for winter. Got a new tool box so I'll have some sort of organization when wrenching. The machines are at a buddy's place and he has decided he's building a couple seacans together for his garage, and said I can borrow some space to wrench on the bike at least to get it purring throughout the cold. I'm hoping to be able to update every couple weeks with questions at least. Or to run ideas by every one.

Re: Yamaha G2 Vs. Ninja 750 Motor
It's just a product photo, but instead of dropping wicked amounts of money on a rear end from an existing machine, the idea come up to maybe use keyed shaft for my rear axle? The kart only has to go fast one time, the rest of the time will legit be used on the course, and the occasional pull down an abandoned airstrip I have at my disposal. Just curious if you think it would handle the torque and pressures in the first place? I realize quality and cheap don't belong in the same sentence but I'm trying to be as inexpensive as possible. Any thoughts?

Re: Yamaha G2 Vs. Ninja 750 Motor
I ran a 1- 3/8 diameter 4130 Chromoly axle, I bent 2 before I added carrier bearings on each side of the drive sprocket, 11,000 RPM launch was kinda hard on it.

Re: Yamaha G2 Vs. Ninja 750 Motor
Ideal. That's what I'd do too.
If they have rules and regs, max out every dimension that you can. Always cheat good (be subtle of course) That 750 will be crazy in a golf cart. Chuckwagon or no..unlike reading about no speed due to using factory golf cart rear transaxles, that solid axle and 12" rims and tires is 100 mph cart. Easy. You cannot stay on it at anywhere near that speed, but it will do it. I'd install a dead man's switch in there. Get tethered up. Be safe Sent from my SM-G965U using Tapatalk |

Re: Yamaha G2 Vs. Ninja 750 Motor
The cradle (swing arm) attachment points on the frame and swing arm will require improvement. Widen out and reinforce the cradle mounts. Mounting motor and axle in a cradle will resolve some chain is issues.
