Good design feature. I think Joker does something similar through its lower triple clamp.

I made a brake line manifold that goes underneath. That hole is for a fitting that goes to the master cylinder and it splits on the bottom to go to both calipers. There are more pics a page or two back as well. Glad to see you still following along Don!

Clever!

Clever!

All in the name of adding a clean flair to a vintage-inspired project. I thought for months on different ideas to make that line split and look ultra clean. The only way to do it cleaner would have been to drill the actual triple tree and fill holes at the ends to make passage ways for the fluid.

You could have also done a closed one from the top, and then angle drilled in on the front face of the top triple to get the split.

I definitely thought about that approach but wanted something more custom and that looked more deliberate.

Without any adieu whatsoever here is a peek at the cockpit as it sits right now. Still need to gather some bits to complete the setup but it will be full tilt vintage race parts. Still need to figure out switches but that's a minor detail.

It took a lot of searching to get that clutch master and it even went back to AP for refurbishing but they didn't even have some of the parts, that's how rare they said it was, having ceased production in the early 80s. In the end it cost a mint but is well worth it.

Cool set of matched AP masters...

Another method for the brakelines..might be what tintop meant, is drill halfway into lower tree, near the middle, then two holes from the bottom at about 45 degrees.. They must intersect with the first one. (Should counterbore the lower holes to get them flat )Tap them to 1/8NPT, and install 1/8NPT to AN-3 fittings, then make your lines.

754, I was thinking along the lines of doing the holes in the top triple close to the master.

Another update. I guess I'm on fire, huh?

Working toward getting the clutch slave mounted. The plate I'm using has been sitting around for almost 10 years waiting for prime time. Got the mounting holes drilled and counter sunk as well as the holes that hold the slave on. Going to 1/8" quarter round the edges of the plate so it looks more seamless with the rest of the cover. The Magura slave is NOS and is the same used by others whom have done this mod.

 :-\not stoked on this mod at all...the cable works fine, hydro clutch on the vf500 has been nothing but trouble

Gday Sean, what problems mate..? I've owned a pile of bikes with hydraulic clutches and never had a problem...

Have always liked the hydro clutch on my RC51.

yeah I guess I don't mind the light lever pull...I think the design on the my vf500 is crap, the slave cylinder gets roasted and  inundated with chain sludge resulting in frequent rebuilds and the friction point at the lever is always wandering around depending on engine temperature and god knows what else.  Just extra complexity that really improves nothing.
     But then if I had that set up, I would want to use it too.  And it would definitely be cool if you are planning on running some monster clutch springs.  Rode a built XR400 with a Magura set up, the slave cylinder was amazingly tiny and really helped manage the lever pull on a bike with a beefed up clutch.

Generally i don't think they have as much "feel" as a cable clutch, but you get used to it quickly...

I've been hitting it pretty hard the last few days trying to get back to roller status and made a huge dent in the process. A few overall pics and the front end in process.

[754]

Looks great, I think shorter headlines ears may look sweeter...

[slikwilli420]

I spotted some ceriani ones at a recent show and now I see that I should have picked them up! They are at least an inch shorter. I'll run these for now until I come across another set.

Man, you must go to some good shows. I don't see vintage Ceriani parts ever.

[754]

Ebay lots on ebay.. But usually. Pricey.
 Picked up two sets of short ears last month.. Finally..Used to get out bid always.
 And a nice billet damper set.
 
 I set though the bolts on one got run in too far and started a tiny crack or little bump on the outside.  Pissoff Cuz the ears were polished.

The really crummy part is seeing stuff you NEVER see and not having the cash to make it yours.

Thanks to JLeather for the primo work on the Joker ignition cover. Awesome customer service from him. Another great piece is now in place.

I just commented on that cover in John's thread...beautiful...

Wow. That takes the Joker cover to a new level.

Thanks RR! It's always good to have you stop by and check out the progress.

Wow. That takes the Joker cover to a new level.

Thanks Don! I'm super excited to see it in person later this week when it arrives. Even something as cool as the Joker cover can have a special touch added. I want everything on this bike to be mine, my own interpretation.
