The neutral safety switch is located inside the the case cover where the front sprocket is. Should be just below the sprocket.

Go to bikebandit.com and search the microfiche. Perhaps its part of a spark advance mechanism. Sounds too small for an internal part , at least for the head. Some times you find a small spring pushing a ball held in by a bolt on the bottom of the engine(pressure relief valve?). Do you have any friends helping that are practical jokers?

The yellow wire can be ran directly to your fuse box and wired to your ignition or to a constantly hot fuse.( always powered fuse) the rca wires go to an amp if you have one.

Hope that this is of any use :

if it has never been removed before, its going to be difficult to remove because of the way the factory puts it on. I have used a pribar to get mine off...it takes some force.

CR 125 is 2 stroke? Rings probably worn out. Check compression, if lower than 85 psi, it wont run.

The best I can offer is a 1980 GS1000. Ninety eight percent of the 1980 manual applies to your 1978 bike. The biggest differences are in fenders, gas tank, decals, trim and seat designs. Go to the site below for a free download. www.carlsalter.com/motorcycle-manuals.asp

check bent bike @ bentbike.com

if it takes a charge off the bike on the bench, (if not replace it) check your fuses.If you still cant run it, the volt regulator (rectifier) may be bad.

Fuel taps or petcocks can be purchased second-hand extremely cheaply from motorcycle wreckers, dismantlers or salvage yards.

Either take your old one with you or take an aluminium foil impression from the tank petcock mounting area. (bolt spacing and o-ring size etc.)

Ask for same or similar model at first to guage availability. Just be aware of the height difference between fuel on and reserve inlet stems.

Cheers.

I hope this helps.

You need to go thru the carb.s again. Looking closely for very small holes in any of the jets. Next will be to sync the carb.s together.

Hello. Go to any auto parts store or bike shop and pick up or order the Suzuki manual for your bike. It will be about $25. but you will use it many times and always be glad you have it. In there you will have all of the wiriing diagrams.

Regarding your current problem check the ground and then check the switch itself. With a 78, corrosion often affects the ground and all of the internal electrical components. Joe

I HAVE LOOKED ALL OVER FOR THESE DIAGRAMS FOR FREE TO DOWNLOAD, THERE ARE NONE AVAIL, THE BIKE IS VERY OLD AND WAS NOT A HIGH PRODUCTION MODEL, IF IT WAS A HONDA 750 NO PROBLEM, THE BEST I CAN DO IS PROVIDE A LINK TO A LOW COST SERVICE MANUAL THAT HAS WIRING DIAGRAMS IN IT.
