Impressive!  I bet you could sell those!!

Thanks.  Tried that with the clutch lifter plates and couldn’t sell enough to keep it going.  Plus I don’t have a CNC mill I can call my own.

Instead of selling on your own you should sell through someone like Kenny at Cycle X. I would give him a call and see if he would stock your part. I hate to see supply for such a great and improved part dry up.
All you gotta do is do what you gotta do.

Unfortunately I don’t have the means to make or have hundreds of parts made and then sell them at a wholesale price to retailers.  I make very little on each lifter plate as is.  I don’t mind not making a ton of money.  I consider it sort of a service to the motorcycle community.  I do have to make something though, but if the demand isn’t there it’s not worth going through the entire exercise.

I stuck a button head screw in the bung, just like the one in the lower fender mounting holes.

Got new fasteners coming for the bracket to bracket connections.


What are you going to do for a crossover for the lines to the two calipers?

That'll be a lot more stopping power.

You're going to need some pretty substantial bolts to handle the torque put on that mounting point on the fork. The bracket on the magna with just one caliper is a lot bigger than the one on a cb. Something else to think about, will the fork brace be strong enough? Again, a lot more torque on the one fork leg.

Just thinking out loud. That is some nice looking parts you got there.

I finally polished the brackets and repainted the calipers.  I’ve got the rebuild kits and all the new fasteners.  I’m going to try and get everything rebuilt and mounted this next weekend so I can figure out what I need for brake lines.

VHT caliper paint.  I plugged all the holes and media blasted them at work first.

Thanks for the link, Steve.  I’ll check it out.

Running a week behind.  I finally rebuilt the calipers and got them mounted on the bike.  It all went pretty smooth.  I forgot to blast and repaint the brake pad dowel pin locking plates (whatever those things are called).  I’ll knock that out tomorrow.

At least I can shop for a jumper brake line and some banjo bolts now.  I think the line from the master cylinder will be long enough.

This is a really cool looking dual caliper set up.  I'm curious to hear how it performs.

Thanks.  I hope it works.

I ordered the brake line and the banjo bolts.  I hope it all gets here by the weekend.

Well, whadda you know.  It works.  I got the new front brakes working today.

I had to reorder a few parts because I ordered some of the wrong stuff, but I finally got all the right parts and got it all put together.  I’m happy to report that this setup works and it works well.  Of course it’s not as good as a brand new modern bike, but it way out performs the OEM setup and that’s what I was looking for.

I rode up an down the street for about 15 minutes, riding slow and breaking in the pads, then I took it for a 10 mile test ride.  No issues at all other than the lever feels just a tad bit squishy.  Might still have a tiny air bubble.  Gonna rebleed in a couple of days.

Overall I’m very pleased with the outcome.  Looking forward to putting some miles on this bike.

Could there be heat issues with two calipers on one disc under heavy use?
Looks great.

Quite possibly, but I’ve seen it done a bunch of times.  I guess I’ll take my chances.  It’s pretty flat around here and there are no canyons.
