Electric Start

I'm not sure I get what your saying, but wouldn't the starter motor spin fast enough to engage youR centrifigal clutch? The starter is for an atv, which is much harder to turn over than one of these little bikes. You wouldn't want to push your start button and have the electric motor start spinning the back wheel.
Your bike sounds awesome can't wait to see the post of it set up
 
Please shed some light of this American made 3.5hp 2-stroke that revs to 9,000rpm. Is it a Robbins Subaru?

No the starter motor is not the generator, you have to have a separate generator as well, hooked into the chain with sprocket large enough to make it work. But not overly large. As far as the nut on the motor, It would take changing the motor cover plate to do it, and it would stick out from the motor and be in the way. but the stater motor I will be using is made to hook into a chain and just turns with the chain till you need it, further, with it between the engine and centrifugal clutch you could start on the fly, If the motor would die on you., because the chain on the clutch is not turning the motor if it stops running. Just freewheeling with the back tire. Plus you can mount it out of the way say under the motor and it will not be sticking out from the motor.
When I get my bike setup l will post it, I am not using a china motor. but is a american made motor. but still a 2 cycle. it can be mounted any way up or down because the Carburetor does not use a float. so that makes it easier to mount in tight places. it makes 3.5 horse and red lines at 9000 rpm. It is not a chain saw motor.

If you look at some of my other post, starting from scratch. The motor I am using is a from a toro snow blower, it's make is a tecumseh 2 cycle and is rated 3.5 hp.
No the starter motor won't spin fast enough to engage the clutch, it is geared down with in the starter. Further if that were the case just increase the size of the Sprocket on the engine shaft till it won't. Further think a moment on how fast a pull starter spins the motor. Meany have centrifugal clutches and that is not a problem.
the generator won't put no strain on the motor then a wheel type generator for a front light, the stater fee wheels with the chain when not in use and is minimal.
 
Just bite the bullet and fab up a system with this motor.

Use a jack-shaft to get the chain to the left side.

here is the wire schematic to hook up regulator, relay, etc..

With a 12V regulator, you get steady output at all rpms.

without a regulator, you get up to 70-80 volts and fluctuation.

I get 42 mph out of this motor with a 3-speed shimano nexus jackshaft between the rear wheel and engine. I have the same engine but not the starter/generator thingy. Maybe this spring Ill upgrade. Im currently on 2000+ miles on it.

That motor is basically a cheap Chinese pile of junk, but is very good value for a 43/49cc 2-stroke. And it has electric start without a really long extension cord to your Makita angle grinder starter dream set-up........laff

Can this electric start bolt onto other engines, like Mitsubishi, Tanaka, Honda engines,etc.?

Does this clone have a longer cranshaft, or a coupler piece?

Eat that, china gurlz...

The starter motor connects to the motor by chain drive, the engine must use a sprag bearing on the engine shaft so that one way starts the motor the other way allows the starter to free wheel.
The other way to do this is to put the starter motor on a steel bracket, so the motor can pivot in and out from the drive chain, then use a small solenoid to push the starter into the chain to start the engine, with that in mind you have to have a two position switch one to activate the solenoid first and the second position to run the starter, further the switch should be spring loaded to pull back to off once you let go. further the engine has to be disengaged for the rear wheel chain drive in some way, or you will need a stand on the back wheel of the bike to raise the back wheel to the start the motor.
One person in this post has said to connect the starter to a bolt on the chain drive side of the motor, which is possible sense this is the same setup the pull starter uses. But you would need to attach a socket to the starter motor in some way to engage the nut, the engine clutch would need to be locked out before staring the engine. The above setup would work on most engines you would need to use your imagination to hook it up. :-||

5-7Heaven,

I think it can be done with some ingenuity.

here's a post on another forum that shows how to remove the starter/stator from a pocket bike engine. It will give you an idea of the parts required to install.

http://www.pocketbikeplanet.com/showthread.php?t=58861

I added a video link on how to remove:

It looks like the starter/stator has a special shaft bolt that holds it to the crankshaft as well as a key on the tapered crankshaft. There's also a special spacer that goes between the starter/stator and the engine block. Update - doesn't look like all starter/stators need the adapter.

Spacer link:

*Again, doesn't look all starter/stators need adapter*

I read thread on the other forum of some one adapting a pocket bike starter/stator to a Robin Subaru 035, but the project wasn't successful. He never posted pictures and was registered as a guest. He had to have an adapter machined to fit the engine. I can't find the post. After the unsuccessful attempt, the poster stopped posting.

Be aware that there are several different starter/stators and each has a different bolt shaft. Look on the NeoScooters site.

Good Luck,
