Great pics,keep em comming!

I have a simplex without a motor. I have a briggs that might fit. It is nice to see that a
simplex can be up dated with a newer motor. Got some Ideals from your pc's thanks Bill Marcum

Welcome Bill. Is your goal "tricked out fast & cool", or "vintage looking" for a final project? That can have an effect in your consideration of a replacement engine. I prefer the vintage look myself. Some of the guys have done some pretty creative things with them.
If time ever becomes plentiful & I run across a simplex chassis w/o engine, I've got a 2 cyl. briggs flat head that I'd like to try a "Zundapp" style mounting (crankshaft going north/south). I'd run the out put thru a angle drive to a belt / chain tranny. If Sonya would just hurry up & buy that lucky lottery ticket......

Like to get started on this project soon . It has been sitting in the garage too long. But like everything time and money is short. I will be getting it out soon to start the project. great web site , it has got my intrest back up .

I have to look for a diffrent motor for my Simplex the briggs that I have and was going to use is junk ( broken cam shaft ). So I am thinking of the Honda Motor may be the gc 190 or the gx 200 . Were do you find these ? What type of motorcycle , and year ? The pic's of these motors look like they fit the bike pretty good. Bill

I stopped by a Harbor Freight store yesterday & took a quick look at their engines. With a tape measure, I took a few quick dimensions......14" long (10" from crank centerline to front, 4" from centerline to back. Without the gastank (setting on top), it's about 8" tall. About 13" including the tank. This was for the 6.5hp version. Didn't have time to take any more dimensions.

Mine is about ready to have mountiing bracket started. If you need any deminsions let me know.
One thing I'm pretty sure of is that it is going to be difficult to install with an electric starter. It adds about 2 inches to the length. I'm going to get serious about getting it mounted this weekend.
Sure makes me nervous cutting those two vertical cross-shaft supports but after looking at the pictures of the other conversions, I guess it is necessary.
-
Personally, I think the Honda GC series motors would be the way to go. They use an upright cylinder, a front exhaust, and a rear carb, just like a simplex.
This one used a chain to a jackshaft, and they to a belt final drive. If I were to build one, I would go with a belt drive clutch to the jackshaft. I bet this could also be done with a torque convertor, and all belt drive.

Ric , Were did you get your motor and what size is it.
-
Not mine. It belongs to BJM.
-
Rick or any one,
I tried to get in touch with BJM. I tried sending him a message but it does not seam to work. I just went down yesterday and picked up my new Honda GC160 motor. BJM supose to have some infomation or parts that would help me with my instalation. Your help would be appeciated. Also I need to know how to post pic that are larger than 1500 KB my new cameria takes pictures around 2.8 MB range, Can i crop them to get them below 1500 KB , or do I need to do something diffrent, Bill Marcum
-
You really need to resize them to about 120 kb to fit the screen so we don't have to scroll. On a Mac I just go to preview and adjust size, for a pc I don't know.
I will try calling BJM on Monday and see if I can get some info from him and maybe he will come over and post it. It looks like there would be interst in a bolt in kit!

Been playing with the computer. Learned how to compress my pictures, now to try it out on this site to see if the pictures will post . This is a test and only a test if it works look out here come some pictures. Bill Marcum

Nice job! That wasn't that hard!

You can Go Bigger Bill.
Although you have the Basics down fine, more info is available here (I just put the tutorial up): http://www.simplexservi-cycle.com/index.php?topic=234.0 (http://www.simplexservi-cycle.com/index.php?topic=234.0)

I would be intererested in this info as well! To make a daily driver of one I think I would need to use the 200cc. Any gusstemates as to top speed? Not looking for a racer but something to carry my 200lbs up a couple of long steep up hills on my commute.
-
I spoke with BJM. He had a health issue and was slowed for the last couple of weeks. He told me he will get with the waterjet guy and try to get back to me by the end of the week. I'll keep everyone informed.

Cool. I'd love to know about a bolt on kit.

Went for a ride to pick up some suppies for my sand blaster. Got to see a Simplex time clock at an antique shop in Monroe Mi. You have to wind the clock but the time clock part is electrical. Bill Marcum 8)

I don't think those clocks were built by the same company.

Simplex was a pretty common name for stuff back in the day. I have an old Simplex house jack over in the shop somewhere.

Just converted my Comet CVT to belt drive instead of chain output. Running a chain final drive proved to be too complicated. The stock wheel is now usable.
Now to install it.
-
Do any of you have photos of your progress?
I have everything to run a belt drive off of my Comet CVT. I was wondering how reliable the final belt would be when running 40 mph.
-
I believe the Simplex ran that speed stock .
