The center stand switch is located on the exhaust side of the bike underneath. Reference the attached photo

 

And the switch looks just like the one on the side stand. Buy a small can of spray chain lube and give it a shot each time you change the oil. That's what I do with mine and it has never stuck in almost 49,000 miles.

 

Wow, thanks for the tip...
But, guess what I found...this has not been on the board before...

The center stand switch had become un-bolted/un-screwed and was JUST HANGING THERE!!!

so, do I look for bolts or screws to refasten it?

 

The bolts that hold the side stand switch and the center stand switch on are the same. If you want to buy them from a Suzuki dealer the part number is 01550-0620B but be prepared to pay a high price for them. I would just take one of the bolts out of the side stand and go to a hardware store or auto parts store and buy two the same size.

I would put a little locktite on the bolts before I put them back in.

 

Now the issue is how to correctly put it back on, and
...when the bike is running should the switch be depressed or out?
...does the switch go on the bottom side of the bracket or the top?

 

When the bike is on the centerstand the plunger is depressed, running it is not. The switch should only go on one way so shouldn't have much of an issue there :wink:

 

The problem appears to be something else.
When the switch was just hanging there it was in the out position, and may have been that way for some time.
Now that I have it reattached there is no improvement. It remains in first.

Maybe the switch itself is faulty. There is a sound when it is running. Like debris, scratching...is that what a bad belt sounds like?

 

An easy way to determine if the switch needs cleaning is to take a multimeter and set it to ohms. Then using the probes on both the connection points on the switch, work the switch in and out. The meter will show close to or at 0 when the switch makes contact internally and 1 or blank when it's not contacting. If it transitions between those two states easily while working it, your switch is good. :thumbup:

 

Just to clarify:
When I said there is a sound of debris and scratching, I was refering to the sound of the engine or transmission.

But, it looks like I will have the mechanics check it out....
maybe they could explain what happened to that missing transmission filler hole long bolt/plug thing.

 

There is swtch on the sidestand that will keep the scooter from running when the stand is down.

 

Just out of curiosity, why does the 650 have a centre stand switch. I understand the need for a side stand switch as a safety feature but you are unlikely to ride with the centre stand down.
Just wondered, whats it for?

 

My assumption was it was meant as a safety precaution when being ran on the center stand to possibly protect the cvt/engine during an accidental dismount while throttle was being applied. Of course, that's a far stretched guess :?

 

I guessed the same, but you would think it would have one on the 400 too. I guess if you wound it up to max rev's and then pushed it off the centre stand it would have the devistating affect!

 

Without an ecvt on the 400s, there wasn't a dire need for one givin the standard cvt isn't as prone to catastrophic damage for such circumstances. Unless they were to design one in so that when the bike was being ran on the center stand, pushing it off would kill the engine. Of course the ecm would have to be programmed with logic for the bike being started normally off the center stand for it to run.
