Installing the neutral switch
« on: June 22, 2009, 06:34:52 PM »
750K7 bike

I've pulled the old switch out and am getting ready to put the new one in. It looks like the switch can go in two different ways. There's a little hole towards the end of the switch. Does this hole face the front of the bike or towards the back, or does it matter?

Well, since it doesnt mention any specific way in the manual, I guess it doesnt matter.

But man, Im having a tough time getting the switch in.

Man, I could use some help. The switch just wont push in. How hard should it be? Does it matter if Im in neutral or in gear?

Sweet! Got it in. Used a car jack and gently nudged it in.

Quick question though. I am replacing both the neutral switches in my 750K7 and 750K3. When I pulled the switch from the K3, the oil completely drained from the bike. I have a nice 3.5 quart mess on the driveway. I had heard that removing the switch shouldnt do this. Anyway, so when I removed the switch from the 750K7, I put a pan underneath and not a drop came out. Both bikes were in neutral when I pulled the switches.

Im afraid something is seriously wrong with the K3.

Any thoughts?

If you are using a new o-ring form Honda..... there have been problems as the replacement oring is slightly larger than the original.
In addition to assembly difficulty, I had a dim neutral light at all times.

Shouldn't be serious...Its likely the leak stopper valve in your oil pump thats supposed to hold the oil back in the oil tank when the motor isn't running.

Is that valve accessible without taking the engine out?

Yes, you can get at it without pulling the engine, but you have to drop the oil pan to get at the pump.

Check your oil tank after your bike has been parked for a while, a couple hours, a day, a couple days, a week. See how fast it is leaking down into the sump. Hows your oil pressure in the first minute after starting?

There are lots of threads on leak stopper valve.
Its really not a big deal but I have heard that the necessary repair part might be unobtainable.

The neutral switch is hard to install if you put the O ring in the hole first. Put the O ring on the neutral switch instead and it will slide in like butter.
