CB750 neutral light

(1/2) > >>

Seamus:
Hello All,

My neutral light is playing up on the K1. It used to work prior to the rebuild, but now stays on. I have tried disconnecting at the switch to see if it is a short and it goes out. Occasionally it will now extinguish in 3rd gear. I guess the switch will have to come out, and hope that I don't have to drain the oil for this. Anyone know if they can be cleaned or is it time to replace it?

I was hoping it would just settle down and work and to be honest was more interested in getting everything alse tuned etc.
As I have not posted and pictures of the beast, I have attached one here.

Hi Seamus, now that is a nice looking bike you have there, as to your neutral switch are you sure that the switch itself is located correctly ? On mine there is a definate right side up for the clip that holds the switch in place, though for about 20 odd years it was a chafed cable that made it stay on. When I was playing with mine I did not lose any oil removing it, check that it is working off the bike before you splash any cash.

Cheers

Seamus:
Thanks Den. I fitted the switch when the engine was on the bench

See picture

So I am pretty sure that it is correctly fitted. I will pull it out and test on the bench. I just did'nt want to drain it down as I have just got it onto the road.

Cheers

hi try tightening the 10 mm nut the holds the switch too the engine case it might have worked loose ,( if its the same problem i had ) and you shouldn't lose any oil if you have to remove the switch, it works off the gear selector drum its well up from the sump ,i think the switch has to earth to work the neutral light so it could still be  bad wiring

Seamus:
Hi Steff

I think I torqued the bolt as per manual at rebuild. It has not worked at all, unfortunately, but it is still worth a go in case I missed it. Thanks for the suggestion. If thid faile, I'll pull it out and bench test
Regards
Seamus
