what 750 forks do i have?
« on: April 28, 2012, 07:22:38 PM »
My 750 is a mishmash of parts. 
I realized today that my front right fork is missing something, like a caliper and caliper ARM, and my front wheel should have a rotor on the right side to match, but the rim doesn't look like its shaped to receive one.
Is love to adapt a dual front but I need to know what I'm starting with.
I think my rotor is from a 79/80?
What spoked dual disc front wheel would fit if I could find a caliper for the right side?   Or is there a different route should go?
I can.easily post different pics if needed.....

Are there any identifying marks to look for on my forks that might clue me in?

Your K only came with one brake but you can upgrade to dual discs with just another caliper, arm, and rotor. Your hub and wheel should work fine but you will need longer bolts. That disc looks like the ones that were on my 78 with the comstars but I didn't think the offset would work with those forks. I will try and find the thread with details for a dual disc conversion.

Doesn't look like I can do it with this hub though.  :-\
This is the right side.

That's what I thought, too.
I  guess I might be best finding a front with dual discs already, and another caliper to fit....faaark.  :o
Thanks bud.

Anyone have the right hub for sale for what I want to do?  :P

OR.... 1975-77 GL1000 front end conversion. The whole shebang can be found cheaper than 750 parts. Just wait and parts will pop up. #$%* sometime you can find whole GL1000's for free on craigs. Food for thought anyhow.
