dry clutch setup?

[boghog]

hello all,
i have a 75 xlh and i'd love to be able to run an open primary with a belt. does anyone make a setup like this or is it impossible to run a dry clutch on this year sporty? thanks

I have always wondered why you don't see many Sporties with open primarys. It must not be compatable with the tranny fluid. I would like to see some modded this way but don't think I ever have.

I think it's been done but it's a high custom deal.
The inner Primary case doesn't come off like on a BT and the crankcase to primary passage has to be plugged off.
I'd contact Rivera engineering's tech support and see what they have to say.

The difficulty in doing an open primary on a sporty is that the sporty transmission and primary are open to each other and share the same fluid. The tranny on a BT is seperate from the primary so it's much easier there. You will have to plugg the existing passage ways between the primary and the transmission and then add new holes to sdd/remove oil from the tranny.

Here's an old thread with more details. There are some links in the sixth post in that thread to a German company that has an open primary kit. http://www.xlforum.net/vbportal/forums/showthread.php?t=4739

I've also seen links to a bike somewhere that someone actually cut the whole tranny off their sporty motor and attached a BT tranny. I can't remember where that was though anymore.

www.ledsled.com They cut the tranny off a sportster engine and use a dry clutch setup.

my dad's 57 sporty has a dry clutch in a sealed drum while the chain and tranny are still in oil. you could try a earlier sealed drum with dry clutches.
