I have a Kerker 4 into 1 exhaust that came off my 86 Radian. Message if you’re interested. thanks. $150 plus shipping

I have a broken throttle adjuster. Do I need a whole new throttle cable or is the adjuster a separate part that I can buy?

Some years ago, I was rebuilding my brake calipers, and determined that they had corrosion in the seal groves. I decided to rebuild them, anyway, with poor results. I couldn’t properly bleed them, as the corrosion caused the seals to leak air into the system. I then swapped those calipers for a set off of my parts bike. This set also had corrosion in the seal grooves. Next I bought a set from Ebay. The Ebay set also had corrosion in the grooves, as did the next 2 sets that I bought. So, I went through 5 sets of calipers that were all corroded. I discussed this with various people, including Derek, and came to the conclusion that most, if not all, of the Radian calipers out there have this corrosion. The issue is that the Radian calipers are raw aluminum, only painted on the outside. If they had been anodized, they would not have corroded. So, what to do? Derek informed me that he had identified a set of Nissin calipers that covered the same swept area as the Radian calipers, and that they were also anodized, so they should never corrode. The Nissin calipers also have 4 pistons, as opposed to the Radian’s 2 pistons. A thoroughly modern solution to my Radian brakes woes. The downside of this conversion is mainly the expense. It is not an inexpensive solution, and probably will not be embraced by the majority of Radian owners. I spent nearly as much money on the front brake system as I did when I bought the bike circa 2005. When I first installed the calipers, I also installed braided stainless steel brake lines, running 2 lines, as opposed to the stock system that runs one line that then splits in two (the junction is under the headlight). I decided, upon consultation with Derek, to keep the stock master cylinder, in order to save a few dollars. Derek assured me that the Nissin calipers would work with the stock MC, although performance would not be optimum. He was correct, and, while my front brakes functioned ok, it really was not a huge improvement over stock. It was nice to know that the calipers would not corrode and leak, and were therefore safer, but I would have liked a bit better feel at the lever. I should note, that when I originally purchased the brake lines and calipers, Derek and I discussed the fact that, ultimately, I wanted to upgrade the MC. As a result, he suggested that I install brake lines that were longer than the stock setup required, as the upgraded MC would need the extra length. I’m happy to say that I did this, and had no issues with the extra length: The lines were not too floppy, or anything like that. I finally bit the bullet, and bought a proper Nissin master cylinder to mate with my new calipers a few weeks ago, and spent an afternoon mounting and bleeding the system. I am thrilled with the results! The new MC transformed the brake feel, making my bike better than ever! It’s an absolute joy to ride and use the brakes, it really feels like a new bike. Prior to this, the most impactful upgrade that I made was installing straight rate springs that were appropriate for my weight. Here are some photos of my set-up. I want to say that this is not a straight bolt on solution. I had to do a bit of fabrication/modification to make the system fit, and I am very happy with the results. Fabrication-wise, I had to create a “stand off” to mount one of the clips that secure the brake lines to keep them from flopping around. If I had mounted the clip to the existing place on the forks, it would have forced the brake line into a sharp bend right above the left caliper. The “stand off” moves the clip’s mounting point about 1-1.5 inches to allow the brake line a straighter path. I also needed to cut a bit of sheet metal from the headlight mounting bracket, to allow the 2 brake lines to pass through the space where originally there was only one. That’s about it for the modifications I needed to make. The “clips” that I am referring to, that secure the brake lines, were machined by Derek of Moto-Lab. I bought 4, but only used 3. Each clip is machined in 2 pieces, with numbers (1,2,3,4) on each of the pieces, as they are all matching, and not interchangable. So, you just make sure to pair 1 and 1, 2 and 2, etc. The clips are not cheap, about $10 each, if my memory serves me correctly. They are beautifully machined by Derek, and he has to charge appropriately for his time and machining equipment, so I don’t begrudge the price. I was just a little surprised at the cost for these little clips. They function great, though. They grip the brake line snugly, and after several years of use, I don’t see any pinching, or abraded areas on the brake lines. I don’t know of any other solution that would allow me to secure the brake lines as efficiently and easily. I guess I could have tried to make a set, myself, but I really don’t have the skills, time, or equipment to do a good job of it, so I consider it $40 well spent. I mentioned that I only used 3 of the 4 clips. I am using one clip just above the left caliper, mounted on the aforementioned “stand off.” I left the right brake line unsecured coming off of the caliper. The right brake line has a shorter, straighter run up to the mounts under the headlight, and did not seem to need to be secured. After a few thousand miles of use, I see no ill effects. The other 2 clips were used to secure the lines to the headlight mounting bracket, in the same spot that the splitter for the 1 into 2 brake lines used to live. I don’t recall if I fabbed up a custom mounting plate, or mounted directly to the existing points…it’s been a few years. I do recall that it took a bit of finagling to get them to sit properly, without stressing the brake lines. Once mounted, however, they have worked just fine for thousands of miles. As I mentioned, I did the brake lines and calipers several years ago, and I mounted the MC just the other day. When I purchased the MC from Derek, he suggested that I might want to upgrade the fasteners to stainless steel, instead of the fasteners that came with the MC. I took him up on the idea, and I am pleased with the stainless. He also offered titanium connectors, but I decided to stick with the stainless as all of the other fasteners that I have upgraded on my Radian are also stainless. Mounting and bleeding the MC was very straightforward. The MC has a bleeder built into it, right up at the top, where any air might collect, which made the bleeding easy. You may notice in my photos that I also have a bleeder valve on my top banjo bolt, which is a holdover from my stock MC setup. One thing to note is that with the Nissin MC, you will lose the mount for your rear view mirror, so you might need to come up with a solution for that. I use bar end mirrors, so this was not a concern for me. That is about all I can think of to tell you about my upgraded front brake system. I am super happy with it, and I know that I will never see a return on the expense if I ever sell my Radian. This does not bother me, as I don’t expect to ever sell my Radian, and riding it with the upgraded brakes makes such an enormous difference that, to me, the expense has been totally worth it. Please feel free to hit me up with any questions that you have about the system. Also, please excuse my grimy, rusty motorcycle--she is no trailer queen. Thank you very much, Derek! By gum, you’ve done it again! Regards, Rich

Indicators stopped working…..does anyone know where the indicator relay is on the Radian? it’s not on the wiring diagram and struggling. any help appreciated.

Hello all, Life has changed and I have two young kids now and never get a chance to ride anymore. I have a 1987 yamaha yx600 radian that has been garage kept its whole life. It has just over 14,000 miles on it and mostly original. It has some bumps and scrapes, but never was laid down on the road (it had fallen over before due to clutter in the garage). I wanted to reach out to this group before going public with selling it. Let me know of you're interested. I'm based out of Richmond, VA area. If I sell it, I'm trying to use the money towards my expanding family and some needed house projects. -Jason

Dear all, My bike is being overhauled and is in need of better (new) exhaust pipes and mufflers. In the Netherlands extremely hard to find. Do you have any suggestions? Thanks in advance, Best, Christi
