Topic: Is there a side stand switch that locks out the starter?

[ksmith0034]

1971 Honda CB750
A couple times now I have hit the starter button with my bike in gear and the kickstand down only to have it lurch forward!    Is there a switch available that will lock out the starter when the kickstand is down?  I don't want a neutral switch as it might be necessary to start the bike at a light after stalling.  I am specifically looking for a way to lock it out when the side stand is down.

You could rig up a universal brake light switch and make it work probably.

But i'd spend less time thinking up a way to rig this and more time figuring out why the bike is stalling at a stop.

Is there no clutch interlock on a K1?

Perhaps it was bypassed?

Did that to a neutral safety on my bombardier.  Because trying to get a bike into neutral whilst stuck on the open face of a dune is sketchy.

Perhaps you can adapt a modern kickstand switch to your neutral interlock.

I'm pretty sure there isn't. Not on either of my k2's.

Long time ago I had a cheap one. It was a little container with mercury and it was easy to attach to the sidestand. It didn't work long and on inspection after some weeks I discovered all mercury had leaked away. Still I think every bike should have one (not the mecury one). Why they never made that a law instead of wasting good mirrors with texts, remains a mystery to me.

Think those rolled in around 1974.

I was really hoping someone had done this already.  I'm not an electrical engineer so I don't know if I can make something on my own or not

So was I, as I sometimes forget to retract my sidestand which is dangerous. I often wonder why there's so little ingenuity here. A fine exception I remember is Flybox (http://forums.sohc4.net/index.php/topic,158068.msg1813037.html#msg1813037)

Pardon me, but you have it all backwards. If you need to re-start at a light, then you definitely would benefit form a Neutral Safety Switch. A side stand switch would only benefit you in the garage, but a NSS would be effective in ALL circumstances. If you stall, the first thing you'd want to do is pull the clutch before you hit the starter. This insures you're either in Neutral, or the clutch is disengaged so you don't go lunging forward into a stopped vehicle.

I get the whole side stand idea, but its my opinion they are not terribly effective and they're prone to problems. When you drive away with the side stand down, momentum or friction will often pop it up anyway. But, vibration can cause it to move away from the frame just enough to disconnect your electrics and cause intermittent stalling.

So I'd wire in a NSS from a later year and be done with it. My opinion.

The stock unit on later models is prone to the very failure I mention above, is why more people don't add them but instead remove them. Even Hondaman will tell you they were problematic.

Don't I know it, but it's the way this happens. I had some narrow escapes and I remember in particular departing from quite close to a steep canyon in France where I had paused to make a picture. Scared the wits out of me. It's for this reason models for Germany had to have this special rubber tip (see various parts lists).

If you pull the clutch in and try to start and it lurches forward, the problem is your clutch is not fully disengaging. It may need to be cleaned, replaced, adjusted, do the HondaMan extra lube trick, etc.  Sidestand switches are a pain and the manufacturers went to them for liability purposes.

Well now I know.

The 750A has a sidestand switch, but no clutch!

Because government is evil and laws are oppressive, you may want to be careful what you wish for.  I prefer no such laws and a consumer driver market for factory and aftermarket equipment rather than a government driven market. A switch or lockout is easy enough to add if it concerns the individual. One of the reasons I stick with 60s or early 70s vehicles is to avoid absurd government laws and regulation.

In any event, I'd use a rear brake switch if it concerned me. Also I think the CB750A had some sort of sidestand switch. Maybe that would be a bolt on thing? Aside from that I'm surprised nobody has mentioned safe starting procedure... Always verify the trans is in neutral at least with the neutral light (though I usually rock it slightly forward and back to verify) and pull the clutch in when starting the engine. I also do not use the electric start, have only used it for a while while injured and able to ride again but unable to kick. Being on the bike while you start it gives you control of the situation if you have a brain fart.

Sorry that I broadened the subject somewhat with departing without retracting the sidestand first. Am I the only one that had it happen a couple of times? As far as silly government laws, I think everybody knows where I stand. Bringing on the headlight before you've started is about the stupidiest

Don't tell anybody Delta but I did it yesterday, keep it our little secret 

[Deltarider]

Maybe we could use that silly blinker buzzer that everybody disconnects anyway. Bidding is open.

Just get a kickstand from a K5 or later that has the little rubber thingy on the end.

The little rubber kick up came out on K2.

But that's not an answer to the OP problem.

Correct, that is not what I'm asking about.  I am trying to find a way to lock out the starter when the side stand is down.  Period.

A normally open momentary contact switch mounted on the frame or kickstand bracket that is closed when the kickstand is raised. Wire it into the ground lead for the starter solenoid.

No, that only came in later models.
