Electric remote starter for 250r? Help

[bebogis]

Does anyone know where to find this kind of starters or built one from scratch? any information is appreciated. Thanks

you want to make it electric start with a button? or a remote start like a car?

You're looking for the impossible. You could do it, but in theory only. Your first step would be getting an electric start. As far as I know, there's only one company that made electric start conversions for motorcycles, ATVs and ATCs. The company is called Goki, and I think they're still around, they made an electric start for the 450r.

However, they don't list a kit for the 250r, you would be looking at custom fabrication of stator cover to accomodate the starter motor, as well as a custom flywheel for the starter gear.

After that, you'd be looking at the electronics for remote activation.

So it's possible, in theory. But let's live in reality for a second, it's impossible.

I believe he is talking about one of these??

The new KTM two strokes have electric start. The whole system is only supposed to add about 10 pounds including battery. I wonder if you could modify the clutch cover to accept the starter and drive the big gear behind the basket? Cool idea to add e-start but won't be cheap or easy.

how dare you! wilky you know better then that! btw I still have some of that amsoil left hahaha...

I bet I could design an electric start for it...


you could design it by the inner side of the kick start gear

or the counter balancer.....


beleieve it or not I bet you could transform the coutner balancer into an electric motor itself there is room in there for magnets think about the shaft on the CB.... it could be machined and then make the armature and commutator but the magnets on the casing

either way though it Can be done and is not impossible. just cost MONEY and knoweldge!

the money part is easy.... and if you have it you dont even need knowledge just pay someone to do it.

Oh, absolutely! I could too. If it's going to be a "kit", the stator cover is the only logical choice, much like Goki does for their products. But for a one-off design, the kickstarter gear is a much better location.

With the custom machining and welding on the cases that it would require, I would be willing to do it for $8,000, which is at least $2000 better than Beerock would quote

Actually, I hadn't even thought of the counterbalance, that's a fantastic idea. But I don't think there is quite enough room there.

A normal starter motor is powerful and torquey, yes, but a typical starter motor still spins at like 1000rpm, and then gets reduced through gears down to something like 100rpm. You would need a BIG armature to crank over an engine with a 1:1 gearing ratio, and I just don't think there is enough room to accomplish it.

I wonder if you could do it by boosting the voltage? Throw the 12V through a power supply to boost it to up to 500V or something like that, I wonder if you could get enough power into a small armature that direction.

yea I didnt think about the gearing, but I know the CB is not a 1;1 ratio i think its a 2:1 ratio or 4:1... the cb balances the intake and exhaust stroke or the compression and power stroke I forget... regardless its one of the two i mentioned...

If i recal the gear crank gear is fairly small and the CB gear is larger so the ratio may be ok to turn over themotor..


the one issue is, in that cb case area the one part of the case closer to where the crank is is not a perfect circle... I already took that into account however that means the armature would have to be skinny for the magnets.... unless there is a way to make two armatures on both ends of the CB case area where the cases are circular (both ends are circular for a bit and then the 1/2 moon shape comes up..

if thif the electric motor was made torquey enough it could definately turn over the motor even with high comp... but its all in the design of the motor...

I can already imagine doing this... first you would have to balance the electric motor part SEPARATE from the counter weight parts and once its 0 then put the counterweights on...
