KR-1S.co.uk Forum

Just started today , ok this morning, then appeared on way home. When side stand is put down in neutral engine cuts out. Tried going up and down box. Fault is intermittant as 30 mins after coming home it had cleared. Neutral light works as normal , no false flashes or staying on . Any ideas?

sidestand switch works together with the clutch switch and neutral switch.

if sidestand is out, gearbox not in neutral and clutch is released, the ignition is switched off.

so you'll have to look at those 3 switches and the corresponding wires.

Cheers Jan i linked the neutral and the sidestand, but missed the clutch, good point.

I've got exactly the same problem with my KR1S, started last week but my cut-out has never worked!

So far checked the clutch and sidestand switch operation which both check out fine with the meter and my neutral light is working.

I hate intermittent electrical problems the worst to find. Probably a cracked wire somewhere

Sorry guys hit post button twice - can't delete!!

Forgot to say - it can go for days before the fault reappears

I have checked the ignition circuit diagram and it looks like all are connected through the diode so I have checked that with my meter and all three pairs or terminals work as they should.

Mike me and you both ! , the fault cleared Fri night and has not returned. I started it Sun and Mon and both days no cut out.

Collectivly we must be able to sort this. Only thing ive done recently was take the rectifier plate on and off , which also has an earth wire. Im wondering if a poor earth could effect this.

Pays to have more than one earth wire

Bit of a discovery tonight, bike would not run with side stand down so took of lead. As i did i noticed water in the gap between the sleeve and the two wires. Drained it out , sprayed some wd40 . Reconected, and roberts your uncle.

Mike dont know if this will work for you , but Im going to dry the lead out with a hairdryer then put a blob of silicone sealant on the end.

Just finished putting everything back together after fitting new fuel lines so it's taken a while to check results of interlock switches and wiring clean up.

After I checked all the earths on the circuits I cleaned and sprayed all the connectors with Silkolene contact cleaner before reassembly including the six lead connector to the ECU which the switches eventually connect to.

Started up and stand cut out works as it should (which it never has done before!!) Major success =D>

Steve hope you have also sorted your problem but if not try contact cleaner on all connections (including diode)

Cheers Mike

Cheers Mike , took my tank,seat, rear seat cover , side stand and unplugged everything! Took of the rectifier and battery earth emeried the base , cleaned both Sprayed with contact cleaner then had my tea! Everything put back together and hey presto fired up first time. I have also changed to hotter plugs b9's rather than 10's to help cold starting.
