I would like to pass-by my plans for upgrading my 1945 Servi-Cycle for your comments and help.
Engine: Predator 212cc $139.99 Harbor Freight
CVT: Comet TAV 30 $189.00 Gokartusa
50A coil NR-Racing $109.00 NR Racing
Flywheel w/starter ring $129.00 NR Racing
Starter After Market $149.99 NR-Racing
I will have a belt pulley made for the final drive to retain the original look and to keep cost down. Any suggestions as to the diameter of the pulley to be made? I am 6’5” and 225 pounds and want to be able to do a solid 60 MPH up our Missouri hills. I hope that this combination will do that. The stock setup just won’t cut it.
If any of the above are wrong or if you know of a better source, PLEASE comment.
I want to run lights so I won’t have to worry about after dark riding. I plan to hang the brake light from the bottom of the seat so I won’t have to modify the fender. I want to be able to return it to stock later.
The next thing I want to do is have a front brake. Any suggestions?
-
Well,no help was fortcomming so I went ahead and bought a engine from Harbor freight for $149.00 with a 27 month extended warrantee ($99 for engine and $40p for extended). I have comming a CVT by Comet.
The wheels are the next problem. Workman has not returnedany of the calls I have made. They even answer the phone with a "Hello" and don't identify the company until asked.
If anyone has any suggestions on how to get in touch with them please let me know.
Pirate offers Workman wheels, CB-W110 combo for $225, brake lever $20, sprocket adapter $45, and sprocket (40 tooth) $40.
Has anyone researched these or have any other suggestions?
Any ideas would be appreciated.
P.S. have lowered speed expectations to 45 after doing the math with this combination.

I bought some worksman wheels a few years ago for a horseless carriage project & if I remember, it was all handled thru a phone call. Not sure what's up now. You might check out the horseless carriage replica website to see if they have a better link to the company (they used to).

I've posted info about this in another thread. Also, my 3 wheel truck tribute project has a 6.5 clone motor in it. Did you see BJM's gc160 conversion?
-
I saw an electric starter kit for the honda motors that the clones were patterned after on ebay, complete kit on $99. Can't beat that, assuming it fits your application. Here is the link:
http://www.ebay.com/itm/350489127363?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
My brother is building bikes with these motors mounted in an upright position. They're really fast. Check his flikr page, you'll like what you see. He also has short video clips of the motors in action.

Also, a comment on the worksman wheels. They're strong, we run em on our bikes, and then you are limited to bicycle tires. With the added power of the clone motors, we decided we wanted better tires. So we've just sourced 80/90 x 21 Pirelli MT 66 tires and the plan is run the them on 21 x 1.60 motorcycle rims. Rolling diameter is very close to std 26" bicycle stuff. There is a pic on Pat's flikr page that shows a tire mounted up sitting next to a worksman wheel.
Good luck!

Oh, and one more thing, I forgot to say you can get new worksman wheels from Pat at sportsmanflyer.com. I might even have the components to build you a set. I build the majority of the wheels for Pat and his customers. If you run the predator motor, using a centrifugal clutch and a moped rear hub, or lightweight motorcycle hub is your best bet. The moped hubs are pretty good, have bolt on sprockets and if you run the Puch, or Lelue, you'll find they're near perfect match to the front worksman hubs, they even run the same brake shoes! The hardest part is getting the offset correct....

I just got a harbor freight sales flyer yesterday & it was showing these engines. The pictures were too fuzzy to tell which way the crank turns, relative to the direction the cylinder points. Which way do they go? The blue "robin" motors they used to sell spun the wrong direction than I preferred & I had to mount the motor with the cylinder pointing backwards. I guess it's not a big deal, but it kinda spoils the look. I was impressed on how easy it was to start that engine (first pull right out of the box).

By the way, the Predator is NOT an exact copy of the GX200. It is very close but some of the bosses on the block and the tins are slightly different. Nothing major and I probably would not have known if I hadn't choosen to install an electric starter.
When removing the governor everything looked the same inside.
Seems to be a well bilt engine otherwise.
-
Is the electric start kit going to fit?
-
it bolted up but it will be a while before I'll be able to start it.
Will let you know.
-
Affordablegocarts.com carries clone motors and they have the goodies in stock, look them up on web. Their prices are competitive with Harbor Frieght too.
-
Ive dealt with Pirate Cycles very good cust. service. They list the Worksman wheels for less than Worksman does, and they are having a 10 percent off sale.
-
I'm still kicking around ideas for my build and was wondering if anyone has completely done away with the stock rear wheel and drive system and replaced it with a wheel or sprocket / hub from a motorcycle or moped. If so, what did you use?
-
I'm sure rdolan can answer this, but why? The belt drive is one of the charms of the simplex. No grease, quieter, smoother ride.
-
I have a really tight budget to work with, so I'm exploring all kinds of different ideas. The belt drive is definitely neat, but I was thinking in terms of how much it will cost to adapt a modern engine, clutch, etc. along with the possibility that it might be hard to find all the parts I need to get the job done. I haven't decided on anything yet, but wanted to think about it from lots of different angles before I spend any money.
-
Well I am supprised in my inability to get in contact with either Worksman or Pirate!
With Pirate all I get is a fax machine and no response to emails.
All I need to find out is if I can put a 35P chain sprocket on their wheels.
Has anyone got any suggestions if the pair Pirate sells with the part number CB-W110 will work ok? They have drum brakes and offer a sprocket adapter and a 40 tooth 41P sprocket. My Comet converter is a 35P.
Any help finding out how to get an answer would be appreciated.

We use moped hubs on motored bikes, and we build some real hotrods. They work very well. They are same basic drum hub like Worksman uses up front, but they're wide (130mm) and they have bolt on sprockets. You can lace one of thees hubs into a stock Simplex rim, not sure what the offsets look like though. Pat has pictures of them on his website, so check out his website:
http://sportsmanflyer.com/
It's hard to keep up with all the latest stuff on the website, but if you go to the Sportsmanflyer flikr page, you'll see all the latest hardware, including a complete folder with lots of pictures of the hubs we run.
This link will show you just the hubs:

And this link will take you to the top of the flikr page (be sure to take your time to really look around, lots of cool goodies):

We always have lots of builds going, including some seriously fast bikes that we're working on now. As soon as we get thru those, we'll be building out a vintage Simplex with modern fourstroke power, either a GX200 or GC200. The plan is to build one out then offer a bolt in kit for other Simplex users. Pat builds some pretty high end stuff and Simplex setup will be of similar quality. It's always possible to build on a budget, but it takes more leg work to find the deals.
Rich
oh, and like I said before, Pat lists the worksman wheels (brand new) on his web site, he can make custom rear sprockets too.
-
Ordered wheels from Pirate yesterday. Front and rear with drum brakes front and rear, sprocket adapter, 40 tooth sprocket and front brake lever and cable for $235 plus shipping.
Seems like a very good price. We'll see when they get here.
-
Those retro racers look cool. One question I have is in regard to mounting the engine at an angle (to get that cool look, I'm sure). Since the oil level is now no longer in the original "sump" area, is there an oil pump used in the engine that's still submerged, or???
I wonder if a guy could do the same thing with one of those robbin engines Harbor Freight used to sell?
Mike sa.

Do you have a link to the wheels you ordered? What are you going to use for tires? I just removed the old rotten tires from my wheels and it looks like they're going to need a lot of work. I'm thinking it might be better to just replace them. I'm only planning on putting around at 35 45 mph - if that.

I did not order the worksman as they had another brand for the lower price. The worksman set was about $100+ more. I got the steel wheels because I am going to paint them anyway.
Give them a call. You might have to call many times as there are only 2 order takers (small company) but were extreemly helpful and well worth the effort of reaching them.
I am planning to run Contintental tires.
Good luck.
-
Please be careful running bicycle tires on a simplex. They were never designed to operate at the speed of a motorbike. Compare one to a simplex tire and you will see what I mean.
-
Since I'm running 26 x 2.125 instead of 2.5 inch rims, will they work ok?
If so, where would be the best place to find them?
Thanks for the heads up.
-
I doubt the rims you are getting are really 2.125" wide. That is the tire size. I know worksman rims are 1 3/4 wide, and that is measured on the outside of the rim, so the real rim width is 1 1/4". A 1" wide drop center Simplex rim is 1 1/2" on the outside and a 2" Simplex is 2 1/2".
I spoke with a guy on another site that had chopperus.com 2" wide wheels, but he was switching them for worksman because the quality wasn't there, and they only had 14 gauge spokes. The worksman are built really tough and are used all the time on motor powered bicycles.
I have spoken with the engineer at worksman about having a 2" wide rim made, but he told me I would have to buy 10,000 to get them made!!
As for Simplex reproduction tires, they are made by Coker tire. Google them and some places will come up.
Rick
Oh, BTW, the simplex 26 x 2.5" tire fits on all the simplex rims as well as the worksman steel rim. I have heard they are extremely hard to get on the worksman alloy rims.
-
Does anyone know where I can get a replacement rear axle, bearings, and cones? My axle has damaged threads and I figured it would be a good idea to get new bearings and cones while I'm at it. Do you guys just use standard automotive bearing grease or is a bicycle type grease better?

Post some pics of your wheels. Let's see how rough is rough.

Rich, did you guys ever work on this simplex conversion?

I know its an old thread but I am curious how the electric start/stator worked out for you with the HF212cc. Rick- I dont think they went with the Simplex mods- they did however just break the world record for fastest 173cc at Bonneville Salt flats

I did not use a HF212, but a GX200 clone. I have not hooked up the electric start or the lights yet, but have ridden the bike at the VMBC meet in Portland, IN, and everything worked fine. I will finish it up this fall/winter. During the summer, I just play!
-
Been traveling. Had to remove the starter because of space. Using Comet CVT so had to fab some brackets to move the wheel back. Not done yet. If anyone has used the starter and a CVT I would like to know.
Made a belt drive final pulley for the comet as could not find a rear wheel that would alow me to retain a rear brake and a sprocket on the left side.
Just starting back on project and if anyone can offer any better ideas I would love to hear them
