shaft driven

[Wyattboche]

I know Honda makes a shaft drive v twin. Just can't remember which one of hand. Has anyone ever built a mini-buggy with shaft drive versus chain drive? How come you don't see more shaft driven motorcycle buggys?

The gear ratio would be wrong and difficult to change.

The wheel is driven out one side of the shaft drive housing so how do you get the power to wheels on both sides?

No really powerful powerplant choices.  However I bet a V-65 Magna would do pretty well.

I was thinking of a 9" ford rearend center section. Probably would be to heavy though. the nine inch you can adjust the gear ratio without pulling the hole rearend apart.

Check out Bdkw1s build at the other site.  Goldwing motor with an aluminum quickchange rear.  I like the goldwing because it has a u-joint output instead of an enclosed oilbath setup that would be difficult to adapt to.
 
9" would be way overkill for any motorcycle motor IMO.

Some of the imports have a ring and pinion diff setup that feeds halfshafts instead of a solid rear.  But I doubt that any are extremely narrow.  Could probably find it in any front wheel drive vehicle that also offers a four wheel drive option.  Ford escape comes to mind,Subies, etc.

Goldwing wont scream, but it a torquey little thing .  Didn't many of the Goldwings have reverse too, for old people.

  Since when? You gotta pull the axles,same as any rear end. Did you  mean you can just change out the pumpkin? Still got a lot to do to change it out.

^^ I thought you just pulled the ring gear assembly out and changed ratios. You probably right fabr, I have never delt with one. I have only seen gear ratio's done on a latemodel car before. Must be different setup.

An 8" is similar in style to a 9". A 32 Coupe project my brother started has an 8" in it. He can narrow either. I looked at one when he was doing it. I don't see a problem narrowing one to the extreme and modifying the wheel flanges to bolt a 930 joint to. I think the advantage of one of those is more gear ratios available along with making the change to 930 joints at the same time. He has a 7.3 gear in his pulling tractor's 9". 8" rear ends and I think the 9" as well have a longer axle on one side than the other. If narrowed to the max, the pinion would not be centered. Possibly, that could be used as an advantage tying in a shaft drive bike engine.

I think the biggest advantage to the 9" diff is that you can preset the ring & pinion of your "pumpkins" on the workbench and change them out in the pits with just basic hand tools and a tube of RTV.......

Nissan make a series of nice strong IRS diffs - the model number tells you how big the crown wheel is in mm.

So, R180 = 180 mm crown wheel (approx. 7 inch diff)

R200 = 200 mm crown wheel (approx. 8 inch diff)

These buggers come in ratios down to 4.900:1, have four spider gears and many are factory LSD. There is a long nose and a short nose version, you'll want a 'mongrel' built up unit of the short nose with the 4.9 gears and the LSD centre. It's a viscous LSD, but it's pretty good if you get a new unit (these are the diffs they put in the Skyline GTRs...)

Yup, runs off the starter motor. It has a speed limiter on it than I plan on by-passing.......... Eventually.
 
As for screaming.......... Turbo on 7PSI makes 205HP.

The stability of the shaft drive, etc. then I would consider replacement. Currently still waiting to see.
I'm outa here cuz I'm a SHIT BAG SPAMMER

[Wyattboche]

Why couldn't you put a drive shaft from the splined shaft on the motor connecting it with a cv, to a rear end like a 7.5" ford? Then you could change the gear ratios to suit. Would it be to much stress on the motor? Id use a 7.5" cause they are cheap and easy to find and should be able to handle motorcycle hp and torque.

Back to the original question on the Honda V-twin...........

Wyatt is cheap and easy 

Its good to see you at least admit it.
