Question for the the 4 strokers out there

Hi Butchatron,

I have family in KY [Elizabethtown] and my favorite MB event is in Dawson Springs, KY. I like KY.

I have been extremely busy over the last several months, designing & testing the EZM Q-Matic drive system. I have invested a lot of money and more importantly 110% of my time in developing the best drive system for the 4-stroke IC motors. After a little market research it was clear, both the Honda & HS 49 CC 4-stroke motors are reliable. And I am sure many have voiced their views abut 2 strokes & 4 strokes, but after 15 years of Pro MC racing in the Mid-west I can attest to the difference between the two. All the 4-stroke race bikes were rebuilt once a year, whereas the 2 stroke motors were rebuilt [refreshed] between each race. Facts are facts and 4-strokes are just plain more durable and forgiving than 2-stroke motors.

Sadly the 4-stroke kits got off to a rocky start because of poor engineering, and poor quality control in the drive transfer systems. The drive train problems found its way throughout the industry and even included the famous Whizzer brand.

I found it hard to believe these problems even existed because they were addressed and solved over 60 years ago in the good ole' USA. Many companies made motorbikes, & scooters in the 40s & 50s and managed to transfer the power from the motor to the rear wheel. Some used belt drive, some used chain drive, some used slip clutches, and some used automatic clutches, but all managed to get the power to the wheel.

I guess in our quest to get "something for nothing" we accepted the lack of quality & engineering for price. After a careful review of the drive systems and the suggested upgrades & fixes, I found it necessary to return to the basics. How do you stop gears from failure & whining sounds? Simple, just don't use gears. How do you deal with stretching primary drive chains and whining sounds? Simple, just don't use primary drive chains. How do you deal with undersize, poorly designed clutches? Simple, just don't use bad clutches.

We located American companies, American labor, American parts, and American engineering to fix the problem. Cost more? You betcha', but it works! I have way over 2500 miles on my test bike and ZERO problems. It easily pulls hills, heavy riders, and gets over 175 MPG [mine has continued to test over 200 MPG]. I have tested both the Honda And HS motors, and I like the HS better [is a little faster on top end]. I like the manual & automatic drive, but the automatic is easier to ride and allows for higher ratios for better cruising speeds [lower RPMs at higher speeds].

Hopefully others will invest their money to fix the problems and offer other solutions and maybe lower prices. So far only a few have been willing to gamble their money, and most are using American parts, engineering & labor in the process.

If you elect to construct your own kit, contact me personally and I will share the details of our system for consideration.

If you want details from a non-dealer, ask Ray from MA for information. He had 2 EZM drive systems at Lewes, DE, one Silent Power [manual] & one of the new Q-Matic drives.


Hope some of these comments are helpful in your quest to build your 4-stroke motorbike

Have fun,

Looking at your 2nd pic it seems the design has not changed at all. I was never able to tighten that middle joint enough. From an engineering standpoint it struck me as very bad design. Maybe your 4-stroke puts less stress there than my Mitsubishi but I never got more than a couple hundred miles without having to fix it.

At first I replaced the two pieces with a single solid bar and after a few more modification built an entirely new cage of my own design. Sold quite a few. The 43cc Mit still runs fine to this day.

As to the question of 'spending a grand' that depends entirely on the buyer. It all depends on how much you want to put into the bike. I myself want this bike to look nice. Chrome fenders, ape hangers, 72 spoke wheels, springer forks and all the trimmings. So when the dust settles and the smoke clears, I will have well over a grand into this bike, but it wont be from the engine kit.

to make anything truly yours alone (unique), costs
some can do it from the start, some have to do it piece by piece
that's what makes us all different
