Hi guys,

My Nightrain is coming along nicely, be back from the fabricator next week and as part of my mad changes I really want to tidy up the bars but with something a little different.

I've stumbled across a few threads on various forums where guys have been using radial master cylinders and perches from Sportsbikes; the 7/8 bar width is bored out to a 1' and then fitted accordingly. I've got a set of posh mini switches, an old school clutch lever and perch but can't work out the braking ratio to make it work.

From what I've read 9/16 bore that is standard on my HD is comparable to a 14mm master cylinder - just wondering whether any of you blokes are braking geniuses and can help me work this out?

Here's a few pics of what I want to achieve - any input would be greatly apprecciated 

Cheers
