Default Bill's 2000 Whizzer upgrade and restyling project

Bill is a retired VW-Porsche mechanic that lives about a mile from Donut Derelicts. He regularly drives one of his three vintage Studebakers to the car show and that's where I met him. He has a shop in his garage with a lathe and misc. other equipment and likes to tinker. While hunting a pulley for a Briggs bike project, he came across a former Whizzer dealer that offered him a 2000 24'' bike at a great price. Bill scooped it up, (he road Whizzers as a young man). After replacing 12 spokes in the rear wheel, ignition coil and getting it running, he realized it may need some engine and carb work. I offered to help him sort it all out. Not knowing much about the newer Whizzers, I asked Ray if he may be able to give me a hand. If you know mason_man, you might have guessed he jumped right on board with a ton of info, parts and expertise he has accumulated over the years.


I picked it up Saturday and brought it home. Ray came over the next Saturday and we listed the work it needed. Bill also wants to restyle it to look more like the vintage bikes. Not an easy job for a 24 incher.








As you can see, it's missing quite a lot of the original pieces.

We stripped it down some and added a lot to our list.

Pretty cool you guys coming together on this project. I'm sure it will turn out great and best of all will be the shared friendship of you three amigos. Thanks for doing the thread and sharing the project with the rest of us.

Thanks SB. We've seen you and your friends working together on a few projects over the years. Good to have comrades with the same interests.


Among the items this bike needs are a new front brake arm, some larger rear spokes, new tires, a belt guard, a different rear brake hub and straight handlebars with goose neck. Some of the work needed is a valve job, cylinder threads repaired, flywheel balanced, rear wheel lacing and carburetor jetting. As far as styling, the front forks need lowering as well as the seat and handlebars. Remove the rear rack, reflectors and a ton of unneeded brackets and wiring. Replace the chain guard, control levers and maybe the center stand. Tidy up the wiring that's left and clean up the rust and paint. Wax all the paint and polish the chrome.

Ray has some tuning and performance mods in mind that will make it run better, cooler and stronger.

We'll post photos as we go.

Hi Dale, SB, I have a new edition whizzer belt guard, its plastic. can be made to look more like the vintage guard by removing the front portion that covers the flywheel.
Ill have this ready too. I used a dremel tool with a cut-off wheel, then finish it by filing it down smooth. Looks like the real deal!

Great job on the belt cover Ray.
I cleaned the cylinder, then I did a 3 angle cut on the valve seats and widened them a little for more flow. I took the valves to my friend, Yo, who owns Contemporary Auto Machine here in Huntington Beach, and he ground the valves for me. They lapped in real nice and the guides felt fine.
I installed thread inserts in the holes where the long studs go through and also in the three rear holes that were damaged. Then I lapped the surface flat on a piece of glass. After honing the bore, it's ready for Ray to do his porting and other mods.









Ray had me move the trigger plate on the flywheel rim about 7/16'' advanced.

Next I made a shaft to insert into the center for balancing. Ray says most Whizzer flywheels need it.



Installed it in the flywheel.




And put it on my leveled parallel rails and found the heavy spot.




After balancing, I will clean it up and paint it.

Bill had some nice Wald handlebars and I had a neck that fit and looks good. He is also rounding up some new tires.

Handlebars look better. Engine is coming along nicely.

Parts look really good Dale!
I found the old speedometer, still need to find the cable for it.
Also ill bring one of my lay back seat post that I have.
Replacement carb will a main jet of #76, #78,maybe a #80.
I also made the air/oil separator tube that fits between the valve guides.

Moving the trigger plate 7/16 forward from the factory 14 degrees to 23 degrees BTDC helps the pickup.
