Title: Starter Interlock Switch Question
Post by VRSCDX on 11/17/12 at 10:15:40

Time again to get smarter given the collective knowledge of this forum.  I'm doing quite a bit of work on a 2004.  I took apart the clutch lever on the left handlebar and noticed a dangling wire.  The starter interlock switch was unplugged.  Then I notice the previous owner jammed a piece of copper wire into the connector plug to jump the wires together as a bypass of the switch altogether.  I've checked my wire diagram, and it appears that one of these wires goes to the decompression controller and the other to the starter switch (I assume on the right handlebar).  Does anybody have any idea what this switch does when working properly or why the previous owner might have decided to jump or bypass this switch?????  THX in advance.

When working properly,.. it prevents you from starting the bike, in gear...
When not working properly,... it just prevents you from starting the bike... :-?...

When working properly, it prevents starter engagement unless the clutch is squeezed, whether in gear (kickstand up) or any gear including Neutral kickstand down. When not working correctly, it may either allow starts anytime just as if the switch is bypassed, or prevent starts altogether. It is often bypassed by people who "Don't like all these cursed safeties brought about by the Nanny State."

hi there,,, the clutch switch supplies power TO the control unit via the start switch, so the control unit can power the starter and decomp valve.  i have totaly rewired my bike so i know how it works.
hope this helps

I think I will leave it bypassed.  But I'm going to bypass it properly and not shove a piece of copper wire in the plug to make a bridge.  I very often just like to walk up to a bike and start it to let it warm up while I dress for a ride.  I live in the Nanny State, so I would be inclinded to agree some of our safety issues are overboard.  But how else can our govt workers justify their jobs if they don't make new rules.  And when all the good rules are taken, people just make up dumb ones.  Though I have a couple of new CA bikes that don't have a "squeeze the clutch to start switch."

When working properly you can already crank this one in neutral with the clutch in and then let it out and get dressed. That's my usual method.  :) I always park in first, but it only takes a flick of the boot to hit neutral.

My Kawasaki and my Yamaha are so wired that they will start with the clutch released if they are in Neutral, kickstand up or down. They do have clutch switches and will not start with the clutch released if they are in gear. I prefer that arrangement to Suzuki's. Both, like the Suzuki, kill the engine if the bike is shifted into gear with the sidestand down (or if the sidestand is put down while they are in gear).

Despite all the protestations about the Nanny State, both safety rules and safety interlocks are "written in blood." Both come about because people got hurt or killed. It is true that we learn from our mistakes, but when mistakes are fatal - and some are - the lessons are learned only by others. When they attempt to pass on the lessons, the FNG will say "I don't need no stinking regulations - I'm smarter than that." Draw your own conclusions.

I've got over 350,000 motorcycle miles behind me.

Still, every two years or so, I'll put one of my bikes in gear and it'll quit....then I'll look down and see the kickstand extended.

Back in the pre-"nanny-state" era, about every two years or so, I'd happen to notice, as I was zinging down the road, that my kickstand had been left down.  I even (luckily) had said kickstand scrape into the retracted position every now and again!

I'm not a big fan of vacuum-operated petcocks, but I sort of like the kickstand safety interlocks.....

JMHO!  Your ride, your hide.....

If ya ditch the stand safety, consider a rubber finger that extends past the foot of the stand.

I rode an '81 GL1100 for over 125,000 miles.  It didn't have a safety cutout switch for the kickstand, but it did have one of those rubber fingers you speak of.

Saved me a time or two.....

Digger, it is a little off-topic, but how long is the pre-takeoff checklist for the Shuttle? I have flown Cessna 150/172 airplanes, but nothing more complicated.

You can get around these safety devices until the one day they don't prevent you from doing what they were intended to do.   I know because I once had a square dance session with my Ultraglide when I started it in gear while standing to the side.   Worse, it was in a park full of spectators.

Oh, swing your Harley to the right,
Grab her grips and holdon tight

One of the beauties of having a manual decompression device, a la RYCA, is that the starting drill begins with manually lifting the exhaust valve for a rev or so, just to get the motor spinning over before it starts.  The thing will NOT run with the exhaust valve lifted.  If it was in gear, and you tried to start the bike, you'd feel the bike move a little as the starter tried to move the piston, the rest of the bike, and your fat ass all at the same time.  Not much would happen other than a slight lurch and an expletive.

That said, I don't depend on that.  As the last step prior to pushing down on the decompression lever and hitting the starter button, I move the bike forward or back a few inches just to feel that it is not in gear.

Ehhh kinda...   That's like saying that one of features of the Model T was you couldn't accidentally start it while sitting in the seat.

The advantage of the clutch interlock is what I take advantage of when push starting.

Hit the start button to activate the decomp and let out the clutch as soon as it starts spinning.  this will deactivate the starter w/o having to worry about getting your thumb off the button in a hurry.

Lot of folks used lots of different checklists during the last few hours before a launch.

Mine was not too bad, but still longer than anything I'd ever used on the 40+ different aircraft I've flown over the years.

One tricky part was getting the three APUs started soon enough to prevent a launch abort (not a trivial procedure, btw, involving multiple switches and timing).....just a little pressure there, with the whole world watching!
