clutch switch?
Permalink  
 


Hi went out this weekend got stuck in the mud up to my Knees took 2 of us to pull it out ,couldn,t get the bike into neutral and couldnt start it so I am presuming the clutch switch was disabling the ignition.I can find the stand switch cables but which cables to short out to overide this from happening again.

Cheers Dave

Oh dear, Dave. cry

The clutch switch is on the clutch lever clamp on your handlebars. It's unlikely to be the culprit if it didn't get into the mud. no

It is only used to prevent you starting the bike whilst it's in gear without pulling the clutch in. It isn't used to change gears and if it malfunctions it won't stop you changing gears or finding neutral.

If you can't select neutral after your sludge episode you should check to see that the gear lever isn't bent and catching the engine cover, or jammed on the sump guard or similar. confuse If the lever is OK then it may point to "internal" selector/gearbox problems.  hmm

NO sorry misunderstood I managed to get it into neutral eventually but while it was in gear she wouldnt start,its dificult to rock a bike backwards and forewards in Mud lol.I'm going to have to try it in the garage and check if it will start in gear with the clutch pulled in it definately would not start and I was stuck in 3rd it wasnt untill I managed to get it into neutral that the bike started ok, there was nothing no starter like it was completely dead except the headlight was on so I new the ignition was on bit of a weird one.

BTW is it easy to disconect the clutch switch and can it be done at the loom end or is it a cut the cable and join it at the clutch end.

I've never had cause to try any alterations to the clutch switch wiring, but my take on it is that the two switch wires merely need joining together to complete the circuit. confuse

Try it and see - if it doesn't work then separate the wires and re-try.

One way or the other must work. aww

Don't forget to report your findings so all can benefit. wink

See http://ttr250.activeboard.com/t43731716/modernising-a-1993-yamaha-ttr250-open-enduro/?page=2#lastPostAnchor - third pic down.

Yellow/brown is brake switch and the blue ones are the clutch switch feeds.

I wouldn't recommend doing it for road use but, for enduros, you might well want to remove the clutch and brake switches in which case, as Martyn says, just join the two wires back at the loom for maximum weight saving.

Do it tidily with a looped block connector and it is going to be easy to go back to standard. Same with the stand switch.

I checked again the bike will not start in gear even when the clutch is engaged so switch must be faulty.I will rearange things this weekend.
Thanks again

Dave.

I have just cut the wires to the clutch and side stand switch,I soldered the wires together and sealed them with some heat shrink.I have tried the bike in gear and she starts ok now so wont get stuck again (hopefully)
I took a picture but its a bit blured.

I have a similar problem associated with the above so have not begun another thread.....I had problems starting my 1998 OE today. It had been put away for a week pending delivery of parts from the UK. I could not get it to start in neutral despite many attempts and checking the obvious (!)......took out and tested spark plug......no spark on turning over.....checked wires and fuses etc....spark pug cap and put new plug in......nothing......getting fuel etc ok. Then I noticed that the always rather intermittent green neutral light wasn't glowing so fiddled with the gear lever a little and it came on.....the bike started first turn!........great!......thought I'd take the bike for a spin to check on the operation of the new speedo sender unit.......engaged first gear and engine cut out.....tried a couple more times and same thing.......was thinking about where the activation switch for this neutral light might be and was unsure but for starters examined the clutch lever switch (esp. as I had changed the lever for a new one from UK).....it was a little corroded but intact.....with the engine running it was still cutting out on engaging first gear so tried depressing & releasing the switch manually whilst selecting first......same thing ....and strangely, with a lit neutral switch, pulling in and letting out the clutch lever would turn off and on the neutral light..........will the above dodge of joining the two wires on the handlebar switch solve this problem or do I need to look elsewhere?......I would appreciate some advice!........many thanks!

Hi Pete

The best way to bypass the switches is to trace back to a connector and put in a looped connector block (examples in the pic below) to make a continuous circuit. It then means you can easily go back to original if you or a new owner so desires.

I have come across a couple of cases where the neutral light problem was caused by an internal break in the wire from the neutral switch to the bullet connector under the tank. Can you perhaps temporarily substitute another wire between these points to eliminate that as a possibility?

Thanks for the swift reply and useful information Brian.

As I have had the tank off to fit a new petrol tap,new horn and change the spark plug etc it's very possible I have disturbed something.....

I did read the previous postings about looping but wasn't certain it would cure this issue. I'll carry out the bypass you suggest and try a different wire too.

I'll let you know what happens!

Pete

Not sure why everyone else seems to need this side stand switch?

If I unplug mine, it still runs and starts as usual. I might add that my side stand switch does not work anyway (the switch is faulty).

I don't run the side stand switch it was removed before I rode the bike the first time  , but the clutch switch is handy on hill climbs or is I stall on steep down hills  ext. when  you can restart in gear with the clutch in and I'm under way again.

have had to pull the switch apart a couple of times and clean it if it does fail it wont stop the bike from starting in neutral .

 I don't understand how the clutch switch is handy in any way at all as on most conventional motorcycles one can always start the bike 'in gear' with the clutch disengaged anyway....itseems a most unnecessary complication to me well worth getting shut of........

I wonder how on earth I've ever survived intact without this indispensable device over a 40 year motorcycling career incorporating 7 yrs as an senior instructor from BSA 500 Gold Star to chipped/race-canned Buell XB12R ! ;)

 The clutch switch stops you starting the bike in gear and it racing off on you unexpectedly if the Neutral switch is faulty. It also allows you to start the bike in gear while riding (very handy).

Every modern bike with a starter motor that I have ever seen has had the clutch switch installed for this reason. If you can find one that doesn't, I will stand corrected.

You say that ''on most conventional motorcycles one can always start the bike 'in gear' with the clutch disengaged anyway'' but I highly doubt this is the case as any bike that I have seen with a starter motor also has a Neutral switch. It would be silly not to have one!

IMO- it is well worth having installed.

 Obviously you have never ridden trails with MASSIVE hills where stalling can happen to the best of us. Without the clutch switch I would have to find Neutral (nearly impossible to do quick enough) to restart the bike. This would leave me without compression braking as my bike does not roll-start too well (too much compression).

Electric starting motorcycles may have a Neutral light of course (as non-elec starting motorcycles can have) which is sensible and not silly but not necessarily an additional system that defeats starting whilst in gear......thats often been left to the capabilities of a motorcyclist being able to understand the workings of his or her machine.....

 Well I am yet to find a modern bike with an electric start that does not have a neutral switch (or clutch) that does not effect the starter motor. This would be unsafe (and detrimental to starter gears) IMO as it could be started in gear. I highly doubt motorcycle companies are willing to risk a law suit or damage whilst still in the warranty period.

As I said, once I see a modern electric start bike that has a neutral switch that does not effect the starter motor, I will stand corrected.

 Of course, knowing my background so intimately you know I have never ridden up big hills and never stalled.......goodness.......without a 'fitted' clutch switch you could start with the clutch disengaged in any gear and re-start surely? As regards compression braking how does one turn an engine over whilst its under rearwards load and holding the bike?  Isn't this what brakes are for and their speedy deft application whilst re-starting with clutch disengaged? Or am I missing something and making assumptions too? Please enlighten me!

 First of all, the TTR250 is fitted with a two-way start circuit cut-off. This consists of the neutral switch and the clutch switch. The bike WILL NOT start unless one of these conditions is met (i.e. the clutch is pulled in or the motor is in neutral). So, by not having the clutch switch connected you now can only start the bike in neutral! If you bypass the clutch switch (i.e. bridge the wires together) you now have the problem of it being able to start in gear as this condition is met. I say problem because it is unsafe and could be detrimental to the starter components if it is started in gear.

As for the compression braking question- Not sure why you mention that the bike is under rearward load as the engine would be stalled. I can only suggest that you mean the brakes so- to restart the engine without selecting neutral whilst applying ''brakes'' is easy. Pull the CLUTCH SWITCH in and press the starter button (you should have a thumb so it shouldn't be hard to use the front brake at the same time). Now that the engine is started, you have ''engine braking'' back (and yes, I do have to use it occasionally on VERY steep hills).

Thanks for the clarification Jarrah....it was the bit about re-starting the bike whilst under compression braking that threw me a little....

I can only suggest that you mean you got confused by the sentence in bold text below-

 I am not sure why you would get confused as I (obviously) mentioned that the bike was stalled as why would I need to restart it?

Oh, by the way- if you pull the clutch lever in it engages the clutch not disengages. Maybe you meant- ''on most conventional motorcycles one can always start the bike 'in gear' with the clutch SWITCH disengaged anyway''-as in if the clutch switch is bypassed? That would make more sense.

I guess everyone has their ''blonde'' moments so don't feel bad. wink

It is, of course, a matter of opinion whether you like the clutch switch installed or whether you like to bypass it. I have already mentioned the reasons why I like to have it installed.

FWIW, I would always recommend keeping the clutch and side-stand switches for safety reasons and for mechanical reasons.

Regarding the sidestand, in my early years with a TTR, I had trouble with the sidestand switch so bypassed it. I rode off a couple of times with the stand down and nearly came a cropper on the first left-hand bend so re-instated it and wouldn't be without it now biggrin

Owners choice though!

The problem with my TTR turned out to be a severed (by previous owner) kickstand wiring pair with the plug connector removed and the higher socket just left open......connected the two wires in this socket together and can now engage 1st gear without engine turning off.....am relieved!.......might well however tidy all this area up as would prefer this safety device to be operative!.........thanks for everybody's input.....particularly Brian and a certain antipodean contributor.....I owe you a stubby mate!
