Custom: Jeremy Cupp's Chicken Salad

By

Better known for his custom Harleys and hardtail Triumphs, Jeremy Cupp ended up working on a Yamaha XS650 by accident after a friend dropped one off at his shop, LC Fabrications. The end result didn’t look a lot like the ingredients he started with, hence the name.  >

Late last summer, the shop was in kind of a dead spot, we had a lot of big ideas of what to do for a winter project including a salt flat racer and going back to AMD.  Unfortunately it all hinged on selling our beloved Panster.  We try to keep our personal projects separate from our parts business, so the creation of a new bike is always dependent on the sale of another one.

Meanwhile, on the other side of town our good friend Bruce Walker Jr. (of beerhaulers.com) had his own story tell.  Bruce is “that guy”, you know the one who is so cool the temperature drops 10 degrees when he walks in the room, the one with the big black trucks , sweet little roadsters, and all the fine women.  Bruce had picked up this ’79 XS650 from one of his drivers for cheap.  This bike was near mint condition with only 11K on the 31 year old odometer.   One late night filled with good ideas, Bruce did a nice sawzall  induced hack job on the frame, that is where the bike sat for over a year.  This is where we tie it all together.  

One day I’m at the shop focusing on parts, wishing I was building a bike, and Bruce pulls up outside with the XS-half on his truck.  The “bike” had finally gotten in his way and wanted to know if I could use it.  Bruce said “Man it’s just a f-n Yamaha” and he donated it to the cause. The Beerhaulers are pretty hardcore into traditional American style chops, and just weren’t that interested in this Yam.  At this point I still had bigger ideas in mind, and it took a few months to finally decide to do something with it.   The Panster was still not sold and time to do a bike so we decided we’d just do something quick then turn it over on eBay.
 
By the time we had our XS to roller status the Panster sold to a guy in Germany and we had cash flow to do another build.  I am a guy who’s stubborn about doing things start to finish, but like I said, “bigger plans” and after all this was just an “F’ing Yamaha.”  I began making the engine and wheels for the next big thing, but it bugged me that the XS was half finished just sitting around.  Plus it was starting to come out pretty cool.  So I decided screw it, let’s do this Yamaha and see what we get.

Still trying to keep it simler than our other bikes we hard tailed the stock frame, kept the stock front end, and moved the front wheel to the rear.  The offset brake disc and small rear sprocket seemed the perfect setup to run both on the same side, so the front wheel was modified to accept both and moved to its new location on the back of the bike.  To keep both brakes on the left side we got an XS1100 dual disc front wheel and left side caliper then shaved the unneeded stuff from it as well as the right leg.  The stock front end was bolted up using tapered bearings and custom trees which were designed to work with the front shroud we cut from a piece of aluminum sheet.  The bars were then stubbed right into the thick aluminum upper tree, eliminating the need for clamps or risers of any kind.

For the tank I used an old CL360 Honda tank that I had re-tunneled and cut a 3″ wedge out of the center.  The seat section was a small piece of a flat rear fender that I wedged to match the tank, then I built the rest from 14 gauge sheet.  The LED tail lights were made to fit in the rear.  
The original plan for the engine was to just split the cases, clean, inspect, and reseal everything.  Once I got inside I was quite impressed by just how well engineered this engine is.  I hated to let a good opportunity go to waste so I dug into some of our new found cash and ordered up a beautifully re-cast 750 cylinder kit from XS Performance.  For carburetion I swapped the stock Keihin for 36mm Mikuni round slides.  I did some mild porting, replaced all the gaskets, seals, timing chain and guides then dressed up each piece as I reassembled my new found engineering masterpiece.

The paint color was chosen by our local paint store, this color was a mismatch left over from another job but worked well with the black wheels.  All the other details and doo-dads were done out of my head as the bike came together.   Some of which went on to make up our new line of XS parts.  In the end I decided to name the bike Chicken Salad, a good explanation of what I thought I was starting out with versus what I was able to transform it into.

    Great story, but I’m more amazed Wes posted the story of a hardtail without some snide remark. Are you catering to those Harley guys who called you a blowhard?

      Its a Yamaha so its cool. It it was a Sporty we would be shitting on it. That’s how it works here.

    Very cool bike…nice work!

    Veedy nice, the rear brake/sprocket look neato.

    Chain lube, its associated grit, and the rear rotor are a bizarre love triangle.

    Yet another exercise in function following form.

    That said, the seat suspension is interesting.

    It’s kind of a mix between Detroit Bros. industrial and a Mac Motorcycles Spud. Except it’s got the foundation of a Yamaha. I think this is an excellent indication of a future trend in motorcycling. There will always be a place and a market for $100,000 choppers, but there will be a lot more room for utilizing under appreciated, quality machines. You just have to take the time to make it yours. Great post!
