use what ever axle goes with the forks you are using...I think the rotor is going to be closer to your fork leg than the SOHC rotor would have been....

not sure but i think the hub might be too wide. there may be some custom spacers in your future

I'm sure the forks have wider spacing, don't know about the hub though.

the good news is, the DOHC CB750K forks are 35mm just like the SOHC ones. I know ive seen it done, let me try and find the pic of the bike im talking about. Might help you out some.

Ta Da, here you go: this is a 78 CB750K with a DOHC K front end, im not sure about the triple tree or what exactly he did, I just ran accross the pics. (sorry if im stealing pics of a member's bike)
PS: all the DOHC 750K front ends are the same from 79-82. (minus 81, and 82 for air assist forks, and 82 for dual piston caliper)

Yes, the DOHC front wheel uses five bolts to hold the disc.

Hmmm, that I dont know. I *think* they might bolt up, but you might run into problems with the spacing for the caliper, etc. I just sold a set of those year F forks, and wheels. :/

Hey, I ran accross this link: http://caferacer.net/forum/post.asp?method=ReplyQuote&REPLY_ID=72329&TOPIC_ID=9125&FORUM_ID=4
The guy is building a SOHC 750K and hes got a DOHC front end on his too. Maybe you could contact him through the site if  you need help with your swap?  ;)
