Inside Rat Racer - Episode #44

In the previous episode, I shared some inside details of Billy Lane's Sons of Speed races held @ New Smyrna Speedway during 2017 Daytona Bike Week & Biketoberfest. In this episode, I'll share some of the updates made to my 1921 Harley-Davidson blanked off single cylinder racer, known affectionately as "Rat Racer."

Rat Racer - 1921 Blanked Off Harley-Davidson Single
Michael Lichter @ 2017 True Grit Vintage Bike Show

Between the Bike Week race, and the Biketoberfest race, the only real changes made to the chassis, were to add a set of brass handlebar risers from Faber Cycle, along with a set of  Billy Lanes Choppers Inc. 1" board track handlebars. This allows me to adjust both the handlebar height & angle for comfort.

I also added a kill button, and a compression release, to the left side of the bars. A Biltwell throttle assembly from J&P Cycles along with a modified stock throttle cable gives a self closing throttle for safety.


My 21J motor is numbered in the mid 3400s of a total production of 4526 - 1921 Model J 61ci V Twins. It has been blanked off by removing the rear cylinder creating a 30.50ci-500cc single race motor. I uses a 1924 iron piston & rings.

Left Side
I shared the basic set up of the bottom end of this motor in Episode #8.  The female 21J rod was replaced by 1924-29 model J/JD drilled rod, which is longer than the stock 1921 J model rod.

The longer rod had another advantage. While not changing the motor's stroke dimension, it does push the piston up to with 1/16" of the top (photo below) of the cylinder bore at top dead center. The stock 21J rod stops piston travel about 3/8" below to top of the cylinder bore, which greatly limits the compression ratio and performance. The longer late model rod solves that problem.

I am currently running a standard 21J - 4 lobe cam, with a set of modified cam followers for a blanked off single found by Terry Marsh. I hope to have one of Matt Walksler's race cams installed for the next race.

Standard 21J Cam with Modified Cam Followers


My motor uses a standard 21J Intake Pocket , which has been slightly ported to remove the sharp edges, which impede gas flow. It has a stock intake valve, with a 1923-29 conical intake spring & collar supplied by Competition Distributing. The Intake valve spring is shimmed 40 thousands of an inch to increase spring pressure. A stock exhaust valve was used, along with a stock style exhaust valve spring also from Competition distributing. I am in the process of replacing the exhaust valve spring with a heavier spring from Matt Walksler of Period Modified.

I have two different intake towers I've used. One is after market prototype make by George Hood, and the other is a later model vented tower for the conical spring. Both towers use the ball end JDH style intake push rod. 


Carburetion has been the single biggest challenge of this project. I went through several period Schebler & Linkert carburetors, with little success, and one carburetor fire. Most were for twin cylinder bikes, and could not be leaned down enough to perform well through the whole throttle range.

When I toured Billy Lane's Choppers Inc. and examined his Sons of Speed racers, I found he was using modern carburetors, so I decided to give them a try. The first Mikuni VM32mm was too large, and lacked mid range performance. I then settled on a round slide Mikuni VM26-606 carburetor setup for a small bore 4 stroke dirt bike.

Rubber Mounted Mikuni VM26-606 with K&N Air Filter

While tuning is still a work in progress, the current carburetor specs are:

190 main jet, 22.5 pilot jet, Air Screw 1.2 turns out, 1.5 slide, O-O Needle Jet, 5E75 Needle on the middle notch.

With this setup, the motor starts easily, idles smoothly , picks up rpm, when the ignition is advanced, and pulls well through the rev range. The carburetor is rubber mounted with a piece of high temp water hose, and has a K&N air filter installed.

The stock 21J cast gear case cover/oil pump was replaced with the stamped steel gear case cover/cast oil pump introduced in late 1922.

1922 Stamped Steel Gear Case Cover & Cast Oil Pump

I have used a total loss battery powered ignition system for many years now. It used a 1925 timing case with original points, powered by a small 12 volt Security System sealed battery. My most recent update was to replace the original points with a Gotronic Electronic Ignition. The points were replaced by a magnetic sensor, that triggers a small control box. A Dyna 12 Volt Single Wire Coil provides the spark. Ignition timing is set with the timer at full advance 9/16" - 40 degrees Before Top Dead Center.  The small green LED light on the top of the control box signals the triggering of the ignition as the timing lobe passes the sensor.

Modified 1925 Timer & Gotronic Ignition Control Box

These are the modifications I've used over the past few years. All seem to have worked out well on the street & track, so far!

Billy Lane
, and the Sons of Speed Racers, return to the New Smyrna Speedway on Saturday October 21, 2017 during Daytona Biketoberfest. Come out and see the Sons & Daughters of Speed!

Billy Lane @ New Smyrna Speedway in March 2017
Since I first threw a leg over a dirt bike in the early 70s, I have been blessed to have taken  part in many exciting motorcycle adventures; but in March, I had an opportunity to play a small part in one I will never forget.

Like most of the folks, who play with old racing bikes, I had heard of Billy Lane of Choppers Inc. plans to hold a race for recreated board track racers, and had followed his photo posts of the racers he was building, but knew little of the details for the actual race. When I left my place in Alabama, headed down to Florida for Daytona Bike Week, I was determined to make it to the event. I offered my services as a wrench to American Iron Magazine publisher, Buzz Kanter, who was entered in the race, and he graciously accepted. This was the beginning of a grand adventure!

On the Sunday before the race, I took Rat Racer, my 1921 Harley-Davidson racer to the True Grit Motorcycle Show @ Rossmeyer's Destination Daytona.

When we arrived at the show, Warren Lane, Billy's brother, had his Atomic Metalsmith's 1917 Indian Sons of Speed racer on display. I parked my bike next to Warren's bike, and left my buddy Joe Niles to watch it, while I went to park the truck and trailer. When I returned, Joe told me Warren had invited us to take part in a Sons of Speed closed practice session on Wednesday @ New Smyrna Speedway.

The chance to ride my old racer on a modern half mile banked speedway, was just too big a temptation. My buddy, John Melin volunteered to go along, and help me with my bike, and he also ended up on Buzz's Team.

With much effort, I squeezed my big grit eattin butt into my old race leathers, and hit the track, for the first time since the mid 90s. Riding a bike with tall skinny tires, a 96 year old engine, maybe 8 horse power, no suspension, brakes, or tranny, is a very different experience, but something I will never forget!

After I came in from a few laps, Buzz arrived with his bike. A careful inspection revealed a problem with the rear wheel, and we jumped into action to get it fixed.

By Thursday, Buzz's bike was track ready, and Buzz was working up to speed on the track. John, and I needed to stay in Ocala Thursday, and take care of family obligations.  We returned on Friday for the practice day. All went well until the final practice session, when Rhett Rotten went down hard coming out of turn 4. Rhett was pretty banged up, with a couple of cracked ribs. Buzz came into the pits, and I noticed his front tire was nearly flat. Turned out there was a missing rim strip, and the clincher rim had cut the tube causing a slow leak. John grabbed his giant roll of duct tape, and a new tube, the front tire was soon fixed. The rear wheel was found to have the same problem, and was also repaired.

By race day, I found myself drafted to assist with event scoring. Thanks to a great group of volunteers, who stepped in at the last moment, the event took place without a serious incident.

Harley-Davidson's First Racer - The 1910 Model 6E Factory Stock Racer - Episode #42

By: David L. Morrill

Updated: November 2017

Thurman Constable - Union City, Indiana
Motorcycle Illustrated - November 26, 1910
One of the great mysteries of early Harley-Davidson racing history, is the 1910 Model 6E Factory Stock Racer. While Harley-Davidson had been involved with endurance, and reliability competitions from their very beginnings, they had steadfastly avoided direct involvement in the deadly business of professional racing on the early dirt, and board tracks. By 1910, Harley could no longer ignore the value of race wins in driving sales of production motorcycles. With numerous companies offering specialty racing bikes through their dealers to both factory riders, and select privateer racers, there was plenty of competition.

When the 1910 product line was announced by Harley-Davidson, few people noticed the inclusion of the Model 6E in their lineup, but to a few privateer Harley racers, it would be welcome news. When the 1910 model specifications were listed on a two page spread in the edition January 15, 1910 of Motorcycle illustrated, there was nothing that identified this model as a specialty racer. It was one of five single cylinder belt drive bikes with a rated four horsepower. All featured a 30ci. displacement with either magneto, or battery ignition, and were offered for sale through their network of Harley-Davidson dealers.

Motorcycle Illustrated - January 15, 1910

The only thing that seemed to separate the Model 6E, from the four other single cylinder models, was a was a list price of $275. This was $25. more than the other single cylinder models.

Motorcycle Illustrated - January 15, 1910

But word was already tricking down through Harley's dealers, who were involved in racing that help was on it's way. Within Harley-Davidson the new model was referred to as Model 6E - Factory Stock Racer, 30ci F Head Single.

In April, 1910 the new racer made it's first foray to the winner circle on the 1/3 mile banked dirt oval tack Tuileries Park dirt track in Denver, Colorado. The Denver Harley-Davidson dealer, and privateer racer, Walter Whiting, rode one of the new racers to a win in the  Five Mile Amateur Race for Stock Machines. The event results were published in the April 16, 1910 edition of Bicycling World and Motorcycle Review, however Whiting was miss-identified as "J. Whiting" in the article.

Bicycling World & Motorcycle Review - April 16, 1910
On Decoration Day 1910, a grueling 112 Mile Road Race was held from from Denver to Greeley, Colorado that was open to both amateur, and professional riders.  Walter Whiting, again grabbed the spotlight finishing first, followed by his business partner, W. S. Wunderle  also riding one of the Harley-Davidson dingle cylinder racers. What made this win most noteworthy, was that both Whiting and were amateur riders riding single cylinder machines. Whiting, and Wunderle, beat the top finishing professional rider Joe Wolters time, who rode a twin cylinder Flying Merkel, by just short of ten minutes.  The event was covered in an article in both the June 4, 1910 edition of Bicycling World and Motorcycle Review, as well as the June 15, 1910 edition of Motorcycle Illustrated.

The Motorcycle Illustrated featured one of the few photographs on the new racers.

Motorcycle Illustrated - June 15, 1910
Harley-Davidson was quick to tout their victory over an established professional racer on a twin cylinder bike in their advertising. An ad in the June 11, 1910 edition of Bicycling World & Motorcycle Review mentions the wins at both the Tuileries track and the Denver to Greeley Road Race.

In September 1910, a little known event involving the the Model 6E Factory Stock Racer, took place. Out in Waco, Texas a young rider named Eddie Hasha, was making name for himself winning races in the Dallas on both an Indian Single, and an Indian twin.

Hasha's chief competitor, was the acknowledged Southern Champion Robert Stubbs, who was a former member of Indian's Racing Team, that set several new speed records for Indian at Ormond Beach, Florida in 1909.

Robert Stubbs - Ormond Beach, Florida - 1909
Chris price @ Archive Moto
As the Birmingham, Alabama Indian dealer, and a former Indian Racing Team member, Stubbs had access to the latest versions of Indian racing bikes. This was making it tough for Hasha to compete with Stubbs, especially in the single cylinder race.  Harley-Davidson co founder Arthur Davidson had befriended Hasha, early in his career. Davidson shipped one of the 6E single cylinder racers to Hasha in Waco.  How this came to pass, has never been revealed.  Over a three day event starting on August 29, 1910, Hasha cleaned house against Stubbs, and the other competitors. Hasha won all three single cylinder professional class races with the Harley-Davidson, and a couple of professional class races on his Indian twin. The event was reported in a short article in the September 15, 1910 edition of Motorcycle Illustrated.

Motorcycle Illustrated - September 15, 1910
The fact that Arthur Davidson had provided Hasha a single cylinder racer was not picked up by the press. It may not have been lost on Stubbs, who would have passed it on to Indian's Race Department. This appears to have been the only time, Hasha rode the Harley single, as returned to riding an Indian single in the remaining races that season. Whether this was due to pressure from Indian, or the fact Harley did not have a twin cylinder racer is unknown, but Hasha would remain an Indian rider for the remainder of his career. Over the next couple of years, Eddie Hasha rose to the top ranks of professional racing on the newly introduced steeply banked circular board tracks known as Motordromes.

On September 8, 1912, Hasha was killed, along with fellow racer Johnnie Albright, and six young spectators in an horrendous accident at the Vailisburg Park Motordrome in Newark, New Jersey.  In the aftermath of Hasha's death, Arthur Davidson penned a memorial editorial to his friend, which appeared in the Harley-Davidson Dealer's News in October 1912. In that editorial, the story of the 1910 Waco race was finally revealed:

"The News that Eddie Hasha, John Albright and six spectators met death at the Vailisburg Park Motordrome, at Newark, N.J. on September 8th, was no doubt startling to everyone, but to non more than the writer for the reason that a close friendship had existed, for some time, between Hasha and myself, dating back to the time at dallas, Texas, when Hasha was starting his racing career. At that time we had a racing machine shipped to Dallas, and Eddie Hasha was given a chance to ride against Robert Stubbs, and defeated him. From then on his entry into the racing game was fast and remarkably successful. Not very long ago, Mr. Hasha took up the selling of Harley-Davidson motorcycles in Dallas, but the race track fever got him again and he went back to it. And, while it was with very deep regret that I heard the story of his death, as well as that of John Albright, I was not a great deal surprised, as I had expected it to come in the course of events. But to cause the death of spectators was more than any of us had predicted."

Arthur Davidson Editorial - Harley-Davidson Dealer News - October 1912.

The fellow who appears to have had the most success, with the Harley single cylinder racer was one Thurman Constable of Union City, Indiana. The 1910 Racing Season, was Constable's first season as a professional racer, he logged 52 First Place finishes, in 56 events. His photograph appeared in the November 26, 1910 edition of Bicycling World & Motorcycle Review. This maybe the only photograph of the Model 6E Factory Stock Racer in track racing trim.

Bicycling World & Motorcycle Review - November 26, 1910
He also appeared in an article in the December 1, 1910 edition of Motorcycle Illustrated.

Motorcycle Illustrated - December 1, 1910
Despite the fact, that only a handful of Model 6E factory stock Racers were produced, it appears to have been highly successful. Although, it was always billed as "stock" it's success against highly developed single cylinder racers ridden by seasoned professional riders, leads one to believe that the rated stock 4 horsepower, was a a bit of an understatement. The internal secrets of these early racers have been lost to time. However, they allowed both privateer amateur, and professional racers to purchase a competitive Harley-Davidson racer through their local dealers.  The race wins gave Harley-Davidson a performance image to go along with their reputation for endurance and reliability. As racing improves the breed, surely the lessons learned with these racers, were incorporated into the later production singles.

The Model E single racer did not appear in the 1911 models. The emphasis in racing was moving to twin cylinder racers. They could reach much higher speeds of the newly popular Motordrome boards tracks, and the ever increasing speeds, and subsequent danger, filled the stands with paying spectators. It is clear from Arthur Davidson's editorial on Hasha's death, that Harley-Davidson had no interest in being involved in Motordrome racing.

I am not aware of any surviving Model 6E racers. The identifiers, that would separate them from a normal 1910 Model 6 single are pretty much unknown.  If one of these early racers did turn up, with a verifiable provenance, it would surely command a princely sum.  If that racer could be verified as  the one Eddie Hash rode in the 1910 Waco race, it would be the rarest bit of early Harley-Davidson racing history.
