Are side stand switches non serviceable?

My bike wouldn't start outside work last night, until the battery just gave up, so a colleague gave me a jump start and we got it going again, then I rode to the end of my building to stop and put air in my tyres and when I put the side stand down with the engine running in neutral it cut out again.

So after a long hard stare at the bike, I put it on the centre stand, put the side stand up and pressed the ignition button and it came to life again.

When I got home I used a can of degreaser around that area, then brake cleaner then gave it a good spraying with WD40.
I could see the button going in and out quite freely when depressed and released so that looked okay.

This morning the bike started then stopped dead after 30 seconds, so bike back up on centre stand again and it fired up and ran fine again.

So it would appear it has an intermittent fault, or is just on it's way out.

Do they just need replacing? I couldn't really see through all the chain lube that was covering it what they were really about, other than that it's in an awkward place?

If you unbolt it from the frame & flip it over there are four screws holding it together maybe worth a peek inside for any crap contacts also follow wiring from switch & check terminals in connector block.

I just found one on FazerSpares for £10 delivered so it was a no brainer to order it, but i'll have a play about with the old one once I've got all the chain lube off it.

Sounds to me like the side stand switch is working properly. The bike thinks it is in gear still so cutting out with the side stand down.

I would look at the clutch switch and the neutral switch.

The bike cut out when I put the bike stand down yesterday whilst in neutral, then wouldn't start again.
But when I raised the stand it started and ran fine.

I've had this before it's usually the switch on the way out the stick or short giving you you're problem, check the connector too water gets in there over time it's also possible there's a broken/shorting wire.

Wouldn't start again outside work again tonight, but put side stand up and it started straight away.
Definitely to do with the switch or the attached wire.

I had this problem, it turned out to be a crud on the contacts.
A clean out with contact cleaner and it's not happened since.

On the contacts where, the plug end or did you open up the unit?

Brettholmes89 · « **Reply #9 on:** 24 February 2016, 08:07:26 pm »

The plug end.
Probably shouldn't have but I pulled the rubber boot back on the switch and sprayed some in there as well.

darrsi · « **Reply #10 on:** 24 February 2016, 08:41:38 pm »

I haven't had a real chance to look into it yet, but where does the plug end go, is it under the tank?

unfazed · « **Reply #11 on:** 24 February 2016, 08:50:22 pm »

Plug is under left hand side panel.

Corrosion usually effects the plug, but also the contacts in the unit.

Easy to fix with some fiddly bits in it.

See pic of one open

As i said, i've ordered another anyway so i'll replace it then mess about with the old one.
If the new one doesn't turn up by Saturday then i'll have a go at looking at the old one a bit quicker over the weekend when i've got a bit of daylight.

Fazerspares have good bits, but do not assume it works when you get it, test it before you install it.
The copper contacts often oxidise when they are not used for some time.
A battery, bulb and a few pieces of wire is all you need to test it.

I have had to a repair a few secondhand ones due to corrosion, the one in the picture being one.
I bought it as a spare since they are common across many Yamahas.

If I come across a faulty one now, I just swap it out and repair the original and keep that as the next spare.

Cheers for the heads up, although in all due respect i've never had any issues at all with FazerSpares parts.
It'll be delivered to work first so i can have it dissected by my electronics department for reassurance.

They emailed me earlier apologising saying they've only just noticed my order. $:\$

I thought that only one bolt/screw holding it on was accessible as the other is too close to the engine.

fazersharp · « **Reply #17 on:** 25 February 2016, 09:48:32 pm »

I just looked at a picture I have from when I cleaned inside my sprocket cover - and now I see two screws, is that what I was thinking that you have to remove the cover to get at the other screw

darrsi · « **Reply #18 on:** 25 February 2016, 10:07:09 pm »

All i can see is chain lube.
Haven't seen a bolt yet.

fazersharp · « **Reply #19 on:** 25 February 2016, 11:16:25 pm »

Here it is without the lube you can see the two screws at the bottom and I dont think you get to the one closest to the engine as the sprocket cover is in the way

unfazed · « **Reply #20 on:** 25 February 2016, 11:44:29 pm »

The visible screws in the picture are not for removing the switch, they are part of a set of 4 for keeping the sealing plate and wire guide in place.

2 pan head screws hold the switch to the frame and can only be accessed from underneath and are loctited in place.

Ensure you have a good fitting philips screwdriver but there is a good chance they will be wrecked on the way out.

Use an impact screwdriver to remove as it will fit cleanly and replace then with normal bolts or allen bolts and loctite them back in place.

If switch falls off when riding the engine will stop dead.

I knew there was a reason why I didn't remove it when I was cleaning the area - Yamaha cheese screws

Don't s'pose you would have any idea of what size and length of bolts needed perchance, as i'll try and get some replacements from work later on today?
I've got another week off work from Monday so i'll need to have the bolts to hand at home.

Just saw this now Darrsi, I think they are around the 16mm mark, but not 100%sure
