kick starter

[mike75925]

you could keep the rope. hollow out the recoil wheel to ride the kicker's shaft, haven't thought it all the way through yet! ah hah! kicker will have one way bearing as well as the recoil so that they are independent.

I was thinking maby i could also have a pull rope by using the kind that bolts the the side of the motor where it uses the flywheel ring gear like an electic starter. They used them sometimes on older briggs vertical shaft motors. I have a few

Now that is cool.

That would be fairly easy to do.

Just mount a gear on the square ratcheting thing, then a gear on the pedal,
You could use those steering gears probably!

I started making the kick starter from the steering gears it should work. Maby have some pics soon

Well I was tinkering with the kick start idea and decided to use the pile of bicycle parts I have. It's a little crude but if you like crazy mechanical looking things It'll work. I still have to add some stops and a spring, but it works very smooth and you can get enough of a kick out of it to get multiple spins.

Don`t know of any Kick start Briggs set up but possably a electric start would be easyer to use , heres a link to a flywheel setup but you`d still need a Briggs starter and battery ??

Dude,
That is F-N Awesome.
I'm impressed.
Very nice work.

Got one question, Does the big gear roll back far enough so it will come off of the freewheel?
Just so you dont have a constant ticking?


If this works well for you, I seriously might have to set one up on my bike! Even though its electric start.

Kick start opposed twin
That would be like trying to kick over an xr500 without compression release...

Great work on the kickstarter tho, thats pretty awesome.

Ah, it could still be done though

 

[Kaptain Krunch]

Just make it strong enough.

yeah when I make the stops for it i'm going to have it disengage the little sprocket. I was worried that when I mount this on the modified clone I'm building the RPMs may be too much for the bike sprocket.

I need to find a coil spring somewhere so I don't have a big streched sping lookin' extra ridiculous. I was thinking about looking around the junkyard but I can't think of anything on a car that would use a coiled spring............ maybe the guts out of a car door like the window mechanism....

The only thing that really worries me is the tube on the flywheel that is welded to the sprocket is a bike peg and I had to cut it to length, so I hope that my square is true enough so that thing don't fly apart on me! That would hit right under the leg!

 

[porsche930dude]

Skid that looks great i wouldnt have thought to use the chain like that very cool! But yeah the unbalance of it might be a problem id definatly make a bit of a guard there to prevent the whole chinese star effect that sprocket might have on your thigh
I havnt done much of anything on mine since my last report

 

[Raywelder]

I so want to do this now lol.

Mini bike kick starter

Here are some pics of a minichopper I made about 5 years ago, with a kickstarter installed. It uses a 3hp briggs motor. I made almost everything on it including the kickstart. The kickstart is attached to a driven jackshaft with a 1.2:1 ration between the motor and the output shaft. There is a standard 3/4" centrifugal clutch that drives the final drive chain. This configuration also ends up increasing the stall speed of the clutch for better takeoff. I used to sell plans for the kickstarter assemblies but due to the amount of machining involved it's beyond most home builders. If anyone is interested I can try and find the plans and post them.

Nice bike! That sounds cool, I'm always interested in plans. I got someone to do free machining, so I would have no problem!LOL!

Skid, that looks great!!! But I'm having trouble wrapping my head around something, I need you to explain. With the chain attached to the "big" sprocket, how is there enough room in the chain for the little sprocket's teeth? My mind says there's not enough room. So my first thought was "extra wide chain?", and my next thought was, "Well, the chain's welded on the big sprocket, so it doesn't NEED to have it's teeth in there, so grind them off!"

Am I hitting the crack pipe here, or was there an issue there, and how did you solve it?

Thanks! Chris

 

[porsche930dude]

i was thinking #41 chain its wider and can probrobly fit two sprockets

Your on the mark! The teeth on the big sprocket are ground down, and the chain is a #41 which meshes perfect with the smaller sprocket and it is welded to the big sprocket.

PS: Stay off that crack pipe! That's a bad scene!

Old thread but I'm new and 'kickin' around the idea of a kick starter for my trike and I love that bike crank sprocket set up. Has anyone ever got one set up on their rig? would like some detail on how the free wheel sprocket was attached..
