The Avons are a 3.00x21, and measure a full 27" OD at 35psi.

You could run a smaller 80/90-21 for a 26" OD, but I like the vintage look & the added suspension the tire offers.

The brake drum is a little over 4.5 inches ID, and the shoes a little over 1 inch wide.

Rick:

I just picked up a pair of wheels from Scott.  I need to correct myself here, the production wheels are Aluminum.  The prototypes I handled in his shop were steel.  These are motorcycle grade DOT wheels, so they are plenty strong in aluminum.  Anyway, here are the pics with an Avon mounted:







The drum brake is much bigger than the worksman bicycle brake.

 The Speedometer drive fits a standard cable - and Scott has both cables and speedometers in stock to fit.  Right now the only speedometers available are marked in Kilometers.

Sorry for the lag, I was busy getting ready for the Grange race. 

Scott is mounting Avon Speedmasters in the 21 x 3.00 size for a very vintage look.  DOT legal, and 26" OD

I will get some pics up soon.  The rims are steel, with a decent drum brake laced in.  I believe they would work well with the Simplex front end, just not sure how the belt sheave will match up in the back for you guys.

Bruce:

I much prefer the TIG welded Silver State frame.  Hard to beat a frame & stainless tank for $400

Scott tells me he has some new wheels in the works that will carry a lot more, sealed bearings etc.  Wish I could find a Simplex frame to work with...

No, that is a Silver State frame & tank. 

Actually a whole new bike.  I started with a fresh frame & tank - I sold the bike with that chinese grenade in it.

The engine is a Lifan 118cc 4 stroke, turned so the cylinder points straight up.  I used a starter / generator from a golf cart to give me a 20 amp charging system as well as electric start.  With the side car attached it will cruise at 30 mph.

Been using it as truck lately - cheaper than the pickup for a quick run to the hardware store.

Yeah, I know it has been a while..

The guy with the Simplex decided not to sell me the bike.  I went by his place in Chloride & he told me he thought it was "valuable", since he had located the tank for it.  I gave him my number, and asked him to call me when he had a price in mind.   The next time I was in his area I stopped by...  the bike was gone.  He sold it for 200 bucks. 

I was sort of bummed out on the whole idea & built myself a new sidehack instead:







Worked out all my frustrations on that job, so now it is time to look again for a Simplex.

Engine & Transmission / Re: WICO COIL

PD:

The multiple magnet warning comes from the fact that it will fire when the magnets cross the coil.  On a 2 stroke with balance magnets like old Echo stuff, this means the plug fires a second time @ bdc.  Harmless in those motors.   On stuff with 6 sets of magnets used to produce DC power, there will be misfires of course.

The little chinese 2 strokes we use in the bicycles fire every 180 degrees from the factory.   I would try one on the simplex engine without a second thought.

Nice pics.

Looking at that set of points, all I can think of is how well an electronic replacement would fit there.

I have worked on countless small engines over the decades, and replacing the points & condenser with a tiny electronic module like the Nova II has been the single best improvement you can make.  I have done chainsaws, outboards, 4 strokes, 2 strokes - any single cylinder magneto style ignition.

Engines that sit for months between starts with the points behind the flywheel get a reputation for being hard to start. A thin film of oil or oxide on the points, and it may take 20 pulls to smack the points together enough to get a decent spark.  Since the points are hard to get at, they rarely get checked either.

Electronic "points" operate faster, and can't get wet or dirty. 

Just my 2 cents as a new guy here.

Thanks guys.

I will not be back out in that part of AZ for a couple of weeks.  The owner said he might have the tank "someplace".  We shall see.

The little two stroke in the BTR frame might be a little weak.  I have a 50cc KTM clone that might work, or a 118cc 4 stroke that looks the part.

The lightweight, bicycle based machines are a lot of fun.  The one in the pic is pedal start with a hand operated clutch - pedal, drop the clutch & go.  Only good for 25 -30 mph, but with bicycle tires that is fast enough.

PD:

I was not carrying a camera that day.  Lots of old junk in AZ survives the rust well enough, bit the bike was somewhat picked over.

Engine is missing.  I understand original engines are probably scarce, but since I have been building board trackers with current engines I think I can get past that.

A bigger concern was the gas tank.  Are there any replacement tanks out there?

Forks were bent & the front wheel a D shape - looked like it rear ended a solid object at speed.

I already have several projects, I should post some pics of those I guess.

This is one of the BTR frames I am in the middle of finishing up:

Another "new' guy here.

I have been around motorcycles most of my life.  I have owned a few Harleys, some other brands too.  Last time I saw a Simplex rolling here was a decades ago.   I got in to motorized bicycles a couple of years ago.  Ran in to a local guy making board track replicas at Viva Las Vegas, and I was hooked.

Recently while poking around in AZ I saw what is left of a Servi-Cycle.  A quick look on the internet brought me here.

I am trying to decide if there is enough of the old bike + available parts to make it worth convincing the owner to sell it.

Anyway, that is how I wound up here.  looks like a lot of nice folks on a well laid out forum.
