dog box needs cush drive?
Bob C - 1/10/03 at 11:46 AM

Hi
bike engines have dog gearboxes(?) To use these to advantage you need some resilience in the drivetrain. Is this fact? Could I use a couple of rubber doughnuts in one of the props instead of UJs? what have other folk done? Information would be appreciated.
Thanks

Some people do some people don't. Personally I have not used one as i heard a horrible story that you loose power!! Mines not on the road yet so can't comment on using it, but i have been in a blade bec with a solid prop, there is a little clonking but nothing awful.

I'm sure some other more enlightened people will come along in a bit, so i'll shut up

The use of donuts in your propshaft should not cause a loss of power.
All they will do is to absorb some of the shock loads that a bike gearbox creates.

I have not heard that you would need resilience in the drive train. You may need more pressure to engage the gears though.
I think the resilience idea may have come from the need to remove backlash or free play from the gears.

I drive with a solid prop, as said before there is a bit of clonking but it's not bad.

Cheers - I'm worried that if I use donuts I may have trouble balancing the prop - though fords use 'em on propshafts don't they- at the gearbox end??

PS
While Donuts indeed should not cause a loss of power, if you eat too many you may find it affects your power to weight ratio
(Well someone was bound to say it eventually )
