Ok, I bought this bike from a guy and it has had problems after problems. First the backfiring problem, then missing side cover needed new brakes, new tires.... Now this nuetral switch wich cannot be obtained.  My bike will not stay running without this when parked. I have bypassed it using a toggle switch but c'mon it looks tacky and often confusing. Does any body know how to obtain one. Used or new. Bike bandit nor Ron Ayers seems to have it even listed. It has been cut or something outside the crankcase but as I wired it up it still doesn't work so I just want it replaced when I go into the crankcase for other work. Any ideas?

Nope wrong Neutral switch. That is a kickstand switch. The neutral switch is located inside the crankcase on the right side of the bike. It is a black wire coming out of the engine. The senses when the bike is in nuetral and disables the kickstand kill switch and turns on the nuetral light.

what year is your bike... the earliest ones had a sidestand indicator light that was replaced with the diode set up and de comp relay,etc...(appears suzuki modified the starting interlock circuirt many times) from the three wiring diagrams ive found the neutal switch closes to allow current to flow back to the frame(ground)..is the indicator bulb bruned out ??(pre 96 model) post 96 sidestand diode is suspect...

I'm not sure if this is the correct part, but on the "Gear Shifting"  diagram, thereis a part labeled "BASE ASSY,NEUT"
part number 37720-24B30.  It costs $27.48 at Ron Ayers.

There's also a contact and a spring labeled "KS Pawl" and "KS Spring" that appear to be part of the assembly.

Hope this helps.
