Last episode I was hit hard with life's bullshit obstacles to freedom and creative expression, but that's how it goes. I generally build at least one bike a year and each one represents a milestone of sorts. Or each one represents another year in the life and times of Bandit. I'm not unique. This notion applies to everyone and every project from building a new home, to building a boat or finishing a book. We're so damn lucky to have the freedom and resources to accomplish our goals, small and large. As you sit back and relish any accomplishment, you know it represents a moment in time--hopefully a good time.

Dick Allen
I mention a couple of chapters ago, an illustrator, who has graced Bikernet with his presence, Dick Allen. That name is so revered in the dark halls of the old school biker world. Dick Allen was one of the first and foremost backyard mechanical engineers of the '70s. He designed on of the most sought-after springers, helped kick off belt drives and several Southbay innovations. But another Dick Allen surfaced recently into the grease-stained halls of Bikernet, with illustrations that captured the excitement and action of our Bonneville efforts and now the first 5-Ball Factory Racer.

It's as if he crawled into the shop after the lights are turned off and the dogs are sleeping. He sketched the roller perched on the lift, sniffed the rags for clues to the essence of the build, and the open road dreams behind the late night efforts. Then he captured the action and desires with pen and ink. I asked him recently to send me a bio, because I sensed a long illustration career. Here was his response:

That's very kind of you to offer to run my bio but honestly it makes me want to take a nap just thinking about it. How about a pic instead of my stump pulling flathead single '40 Ariel? We were born in the same year and have been working together for about fifteen years to keep my bank account drained. As the bike approaches completion it appears to be getting younger and younger while I am definitely getting older and older!

Oaxaco
Here's an example from my sketchbook of life observed during our recent trip to Oaxaca.

DDchunks
Bitchin' segments from D&D, but only 1.5 inches in diameter. We stuck with 1 ¾ inch stock components.

So, recently we tore the March page out of the Calendar and flew into April. A running Racer by the end of April--for the Smoke Out in May, is the goal. The pipes were a major obstacle, yet Jesse James, Illusion Cycles, and Roland Sands inspired me.

bracket
I made an adjustable bracket for the muffler, so it could be bolted on in several position, until I knew what the fuck I was doing.

I spotted a tight shotgun system on one of Rusty Coones' Dyna Glide custom built in his Illusions shop. That's the direction I wanted to go for the racer look, not along the bottom of the frame in stock 1915 fashion. The muffler on Rusty's bike was a short/short Supertrapp developed with an exhaust guiding cone built by the Illusion team. The two-into-one pipe was designed at WCC, but I decided to give my own spin to the action for the Crazy Horse 100-inch engine.

It's a puzzle.

I also recently featured a bike built by Roland Sands with his own shotgun Vance and Hines system. Check it out. It also has a very short muffler system, but I had an all-stainless Scorpion sport bike muffler from the mad designer John reed.

pipelevel
A level always helps with a base, but make sure the bike is leveled first.

With Roland's design inspiration, I went to work. I had to make the system run tight to the bike, so ultimately I could install a Baker Drive kicker system to the JIMS 5-speed transmission. It had to run high enough not to mess with the rear axle and not too high for leg burning threats. I had one break; the Crazy Horse engine was designed with the intake manifold running out the left side of the engine. That allowed me to manufacture pipes as high as I wanted--watch the legs, damnit.

My second bracket to the transmission.

Making pipes is a tricky business. This system is teamed with lots of exhaust manufacturers, so I initiated a phone conference with D&D, and they supplied me with various ends and bends to give me a head start. Vance and Hines and WCC were involved with the design and inspirational aspects, and the Boys from Bassani stopped over for lunch and brought a hand full of bends and a chunk of muffler tubing for my speedometer mounts, a very diverse team. Plus nowadays, when you mess with pipes, the diameter fluctuates from below stock diameters to over 2-inch Bonneville racing exhaust performance demands. I took a day dealing with various sizes and ultimately decided on a 1 ¾-inch system to the two-inch muffler opening.

Getting close.

Then I had one of those calm and serene days in the shop--everything fit. It's a Zen thing, when the stars are aligned, and I drank just the correct carefully measured amount of Jack Daniels the night before. For some strange, inexplicable reason, I was tranquil with the dogs wrestling at my feet. The R&B Sirius station shop background music didn't spin any Michael Jackson tunes, and only the 4-tops and Jerry Butler lured me into a false sense of mechanical confidence. I patiently cut, ground chunks of pipes and brackets, then tacked them into place.

In this case, I didn't struggle to make the headers the same length. It will be fast without that, but they're not designed for Bonneville.

I've been making exhaust systems for about six or eight years, and each year I learn. For instance, I was through the roof to find Hooker Header alignment sleeves, only to discover they hinder performance. That meant I had to move more slowly, meticulously and make sure each segment fit perfectly. I also learned that exhaust wrap can also hinder ultimate performance, by being a heat transmitting barrier. Plus I'm still working on my MIG, pipe-segment welding skills. This year I'm going to clamp a bunch of pipe chunks together and weld them at different feed speeds and electrical settings. I'm determined to nail it down.
