Yamaha/Kawasaki Ninja sleeper is back

bikerjoe · 01-28-2016, 04:15 PM

Year and half ago I hit rear end on speed bump and cracked rear end housing fluid drained out and......took me a 1.5 year to find used stock rear end housing then I put the cart back together. Put some new wires, some chrome and running like a champ......
1984 Ninja 900cc motor ..h20 cooled
Yamaha golf cart
jack shaft Ninja motor to Yamaha stock rear end
wheelie bars
custom dual exhaust
Dana 2000 ign
auxiliary swing peddle mounted under dash
1984 Ninja had hydro clutch.. just ran line to pedal ..easy
1984 Ninja is H20 cooled so I mounted radiator up front with elec. fan
getting on it I have not got into 5th gear yet
work in progress

Where did he go?

I was wondering the same thing rifter....Evansville is only an hr north from me. Be nice to have a fellow bike swap guy close by....or to friendly cart drag

What worries me about these Frankin-carts is people putting these monster engines in these carts and not thinking safety. The front suspension of a stock cart is not made for such speed. Stock brakes

I would just hate to see anyone get waned, mauled or kilt

My own story:
I was so proud when my cart cranked, shifted and rolled. With all that hard work, it was like Christmas morning. Grabbed my gps and hit the road. Got it to 51 before I realized,.... no brakes

Sleeper carts can't have wheelie bars.....just sayin...

Hey Rifter, since you seem to be the on board expert here, What do you think of his jack shaft set up?

I looked at it as well as I could, Jack Shafts I think is a huge problem solver, I ran a Mini Sprint rear axle with a 13 front and a 60 rear that was so I could Drag Race and be able to launch with slicks and not bog but with jack shaft you could swap sprockets and have a drive ratio and a play ratio. we really should experiment more with Jack Shafts. But I have to add this, support bearings on the shaft and on the input shaft on the axle should really be looked at too.

That's what I wanted your opinion on, single bearing on this shaft. Would be easier to build, but pulling from both sides I just don't know if one bearing would work well

Thanks
