Just thought many Whizzer owners & collectors would enjoy seeing a twin cylinder Whizzer.

Kenny Thomas has a Whizzer with twin motors mounted side by side and is named "Double Whiz".

Roger Brophy owns a twin motored Whizzer called "Double Vision" and set a record at the Bonneville Salt Flats.

Both Kenny & Roger used vintage Whizzer motors.

Ron Dow designed & built a twin engine powered Whizzer [still un-named], and thanks to Terry McAllister & Ron Dow I now own it [thanks again Terry & Ron].

Ron Dow also designed & built the twin cylinder Whizzer named "Veezer" [or "Vezzer"]. Considering the monumental feat of building the custom crankcase, the camshaft [I think Kenny Thomas helped with the camshaft, but not sure], crankshaft to support 2 rods, double ignition, and twin carburetors, the "Veezer" had to be much harder to build.

The Twin Whizzer powered motorbike in my possession and the “Veezer” use the new edition motors, well at least most of the “Veezer” is new edition parts.


The "Veezer" is now the proud possession of Terry McAllister [the well known Whizzer collector and inspiration behind the famous Whizzer Newsletter] in Illinois.

Ron Dow is now working on his latest Whizzer project, Turbo charged [see post on this site for more information], and who knows what he may do to the next Whizzer motor in the future [can’t wait to see his next ideas].

I have seen and heard the "Veezer" run many times over the last couple of years, and I can testify, it is certainly "one of a kind". The sound of the twin cylinder wonder is fascinating to say the least. It starts easily and idles smoothly, and is down right cool. It is always a “show stopper” everywhere it is displayed including this year at the biggest motorbike event in the USA, Portland, IN. Many attendees at Portland were amazed at how well the “Veezer” started and ran, and I was thrilled every time Terry started it [just love the sound of the motor].

Hope everyone enjoys this masterpiece.

Have fun,

Put it back together & it wouldn't run. Seemed like the timing was off. Checked tappet clearance, carb for dirt, cam timing ( had cam out to install mushroom lifters). Finally got on the phone with Quenton. Here when his bike was made in Taiwan they put the crankshaft timing gear in wrong. The mark was in the wrong place. I lined the cam up with the dot on the gear. To correct their problem they center punched another mark on the gear. After Quenton & I talked about this we agreed that the center punched mark is where we line up the cam gear mark. Works fine now. This must have been missed by Taiwan's Quality Control. :) Am I the only one who has had this problem? ]]> Whizzer Motor Bicycles jbcruisin http://motorbicycling.com/f8/whizzer-cam-timing-12788.html Turbo Whizzer http://motorbicycling.com/f8/turbo-whizzer-12739.html Thu, 05 Nov 2009 21:31:54 GMT Wanna race? Here's one for ya. Got this recently from Quenton. He said it's from a friend of his. I'm laid off from work since then, saw it & thought "I should post this". Hope I get to ride the finished product.

]]> Whizzer Motor Bicycles jbcruisin http://motorbicycling.com/f8/turbo-whizzer-12739.html Make new edition Whizzers work better http://motorbicycling.com/f8/make-new-edition-whizzers-work-better-12400.html Sat, 24 Oct 2009 00:35:07 GMT Just a few comments to help smooth out you new edition Whizzer and make it more durable in the process.

My suggestions will require a fair degree of mechanical ability, however the end results are well worth the effort.

Most likely end result will be more power, consistent power [less fade when hot], easier starting, steady idle, faster throttle response, better gas mileage, cooler operating temperatures, and higher chance you will return home under power, not peddling.

The majority of the work must be performed to the cylinder!

1. Many cylinders have a casting extrusion in the top of the exhaust port [as much as 1/2"]. Remove the casting with a Dremel grinder. Results are all the above because the exhaust charge can leave quicker & smoother.


2. Remove head, cylinder, & valves and "Deck" the cylinder. 99% of the cylinders will have "grooves" cut in the top when it was milled. Solution, use #220 sand paper on a FLAT surface [marble, thick glass, etc] and continue to work the top of cylinder until completely flat and all the tool marks are gone.

3. Lap the valves into the seats with valve grinding compound [available at any auto parts store].

4. Liquid test the valves. After the valve train is re-installed, pour liquid into each port to see if it leaks out the valves. Your liquid selection will determine how serious you are about this test. Water will not leak as easily as gasoline or alcohol, I use alcohol.

5. Paint the cylinder with black cylinder paint. Many want to argue this point, and I don't really care because I have tested this concept hundreds of times and it always drops the operating temperature and beside it looks "cool". The vintage Whizzers had black cylinders.

6. Bake the paint on for 3 hours @ 350 degrees. Some cylinders weren't cured the same as others and this process helps condition the aluminum to lesson the chances of the head bolt threads pulling from the cylinder, and bakes the paint on also.

7. Replace the head gasket with the copper version. The copper gasket can be reused many times, seals better, and transfers heat better.

8. Mill head .060". Place head on same flat surface used for the cylinder and work until all the tool marks are gone and the head is 100% flat.

9. You will think someone put a different motor on your bike, and will wonder why you didn't do this a long time ago.

10. Ride

PS. Many 2005 to 2007 motors NEED mushroom lifters.
