919 clutch switch

Thought I would post this up in case it helps somebody else.

A few days ago I noticed the bike would "throttle up" when I put it in gear. The RPMs would jump from around 1100 up to 1400-1500. I had this happen once before after I changed back from Renthals to the stock bars. I found a wire off of the clutch switch, which is the switch located on the left handlebar that senses when the clutch lever is pulled in. It has two wires going to it. One of the indications the switch is not working is the bike will not start when in gear with the sidestand up, which it should do, along with the throttle up issue.

I checked the wires this time and they were both on. Got out the meter and checked the switch operation after removing the wires. The switch was erratic, sometimes making, sometimes not.

I removed the nut that holds the clutch lever screw/pin, then removed the screw/pin, and pulled the clutch lever away from the handlebar. Then I took a small screwdriver and pushed the switch out of the clutch lever assembly by pushing where the wire terminals are. It pops right out.

There are two holes in the switch. I took contact cleaner with a spray tube attached and repeatedly sprayed in the holes while exercising the switch. All kinds of junk/crud came out. Looked like old bugs, road grime, soap, etc.

The switch has worked for three days now. I think the problem is solved.

Great info. That'll help someone some day no doubt.

With all of the useful 919 information be collected and the growing number of 919 owners in here, perhaps it's time to create a 919 Tech subforum. The Useful 919 sticky is getting pretty cramped. And searching would be easier if it was organized in dedicated subforum too. Just a thought...

I had a similar problem--the little finger that slides in & out of the switch got bent during a lever change & it would get stuck. I replaced the switch.

Good point Ken. Even though a majority of the naked bike members own 919's this forum is open to all naked bikes. At this time I'm somewhat hesitant to create another sub-forum specific to the 919. The Helpful How-To's now contain 8 tips including this one. It should still be easy to find. Lets see how it flies for now.

If I am not mistaken, here's a pic of the switches in discussion:

Yep, that's it. Remove the wires, push on the end with the terminals and the switch will move left of picture once the screw is removed and the clutch lever is pulled away.

Exclamation Check proper operation of this Clutch Safety Switch

This is a matter of extreme safety!!!

One of the checks Honda recommends is that you start the engine, raise the kickstand and put the transmission in gear. Then begin to lower the kickstand to ensure that the engine stops when the stand is lowered.

I submit that I am MOST unlikely to drive off with a lowered kickstand.

However, I AM likely to stall when making a left turn from a stop and to become FRIGHTENED and ENRAGED when the engine won't crank because the bloomin' clutch switch fails to operate!!!

I suggest a more important test which is easily done and especially important if your 919 sits out in the weather:

1) Start the engine
2) Raise the kickstand
3) Select a gear (1st is usually nice)
4) Kill the engine with the kill switch (momentary)
5) Whilst continuing to hold the clutch disengaged, attempt to start the engine.

If the engine does not start, fix the switch!! If you don't have time, short the leads at the clutch lever at least until you finish making left turns!

(Right turns if you're a Brit!)

I think, based upon my two frightening experiences yesterday, that test is much more important than whether my kickstand switch works. The last time I drove my bike off the kickstand was . . . . .

Can't remember!

I occasionally remove the clutch switch and clean it using brake cleaner. Gets grime in it.

Brake cleaner is nasty stuff... I'd keep it away from wires, contacts, hoses, and, well, anything other than brakes... and even then I'd be selective. If possible find some contact or circuit board cleaner to do this cleaning. Using brake cleaner is one of those things that will probably never cause an issue, until it does.

Thanks for the advice regarding brake cleaner. I will look for some contact cleaner. Might buy a new switch while I'm at it. Cheers mate.

Yes, contact cleaner's Hexane is less nasty than brake parts cleaner, regardless of whether the brake parts cleaner is chlorinated or not.

I think that sensor cleaners are a bit more potent than contact cleaner, but are in the same league.

What did pop up was a combination electrical contact and brake parts cleaner.
My guess is that it'd be weak on the brake parts cleaning side of things.

Also found some electrical contact greases.

Thanks mate. Looks like all major brands put out some sort of electrical contact cleaner. WD40, Permatex, Worth, Lucas, Belray etc.
I'll just pick one.

Then get down on your hands and knees and look for a black cylinder about the size of a cigarette filter.



OR you could hold your hand under the hole where you removed the clutch lever and maybe be lucky enough to catch it on the way down!
