One of my ideas is to mount the (or rather
a) master cylinder on the triple clamps...
In other words, run a
cable from the handlebar down to a mst cyl.... and this fitted behind a neat cowl perhaps...... there is a Sportster sheet-metal cowl that bolts right up to any SG set of fork clamps.....
This one...... not the aluminun one

... the idea is to try and get the observant people to do a double-take at a cable-actuated dual-disk set-up....
edit: Oops. fergot to add:
the cable idea above, coupeled with internal throttle, internal wiring and a jocky pedal...... would result in one very clean set of handlebars.....
yeah, i'm working on a cable-pull M/C setup hidden between the tanks.
initially i got a fab-kevin setup, but it's too small diameter, 9/16", 14mm something like that. i still have it.
i then looked at those 'karting' type master cylinders, but they just weren't suitable, again too small bore and somewhat messy to install.
after searching hi and low for a suitable m/c i ended up using a 5/8 to 3/4" rear-brake m/c, later HD, softail/fxr whatever,
this is for twin disc, 8-pot in total setup so needs to move enough oil.
not the best photos, this was when it was work on progress.
haven't access to my final photos of it all at the mo.
i made the brackets, tacked it all up with my mig. but then the machinist/fabricator i work with tigs it all up sweet like.
an important factor was that i wanted the cable-mount to look like it was part of the head casting.
i know it won't be seen, but i know it's there and thats what matters.
M/C mounted to frame.
rubber boot is removed as i was dickin' about trialling stuff.
OCD cable mount. b-e-a-utiful.
mockup gives you an idea of the setup
mousetrap cable used for brake so matches the mousetrap cable on the clutch side.
symmetry is everything.
The MT-cable is modded, cutting off metal-pressing, cut off nipple-tip and thread remaining swageing
screw the clevis on.
final cable is a custon venhill to correct dimensions. this is a test/draft cable.
you could tow a car with that cable?
this is the mount for the m/c and lever.
frame is upside down, so you're kinda looking down onto the cross-tube, yeah?
m/c bolts up through that square hole. gusset for rigidity and the lever mounts in any of the x4 position for various leverage combos.
bottom position has maximum mechanical-advantage, but also requires most travel on hand-lever.
highest position will be smallest mechanical-advantage, but requires least travel from lever.
anyway, thats the deal.
sorry for the derailment gazza.
i suggest you tap into the brake tee under the yokes.
