Help, just got to work on a suddenly ill zxr250. Bike suddenly cut out while riding. Sudden stall so electrical not fuel. Pulled I'm clutch, started fine and away I went. Happened another couple of times until about 100 metres from work when it would cut out whenever I let clutch out. So if it's neutral, it runs fine clutch in or out, sidestand up or down. In gear it runs with clutch in, but not clutch out. My thought is that the sidestand switch is bad. However, I'm at work and don't have tools and stuff to hand. Question: easiest way to bodge cut out circuit to get me home? Sent from my HTC Desire 620 using Tapatalk
Starts and revs fine, let clutch out in gear and it cuts out. Not sure about anything really. Sent from my HTC Desire 620 using Tapatalk
My thought. But I need a bodge to get me home. Can't leave bike here overnight, it won't be here in the morning. Sent from my HTC Desire 620 using Tapatalk
ZXR250 has a male and female connector on the side stand switch, I would undo both wires from the loom, and plug the male to the female wire on the loom together which would effectively close the circuit
Cool, I'll look at that at lunchtime. Are the wires easy to get to? Sent from my HTC Desire 620 using Tapatalk
Just check that your 2 Phillips head screws that hold the side stand switch to the side stand haven't come loose
That sounds likely, given the way it started and got steadily worse. Sent from my HTC Desire 620 using Tapatalk
Hopefully it is only a loose sidestand, the switch is on the loom under the airbox you might be able to see it from the right hand side sitting on the clutch basket behind the frame, good luck
OK, so sidestand and switch are secure. No chance of getting to wiring without pulling tank and airbox. Isn't going to happen at work. Had a quick play with switch and bike seems to working, but don't want to risk it cutting out on the motorway. My other thought was clutch switch. I can get to that. There are three cables. Do I need to short them all together? Would that fool system into thinking clutch lever was pulled in? Sent from my HTC Desire 620 using Tapatalk
Update: Pulled clutch switch connector and shorted outside pins. Bike starter turns in gear and bike will run with clutch out and sidestand down. Hopefully this will get me home and can get a proper fix tomorrow. Sent from my HTC Desire 620 using Tapatalk
Finally decided to get to the bottom of this. Pulled sidestand switch and cleaned and checked. Switch is good, but bike still doesn't run with clutch out. Checked wiring loom to junction box and tests good. Sidestand up and earth gets to junction box OK. My thinking is diode/solder in junction box is faulty. A model junction box is wired different so can't just swap to test. So, has anybody opened up the junction box before? Easy and safe? Sent from my SM-G920F using Tapatalk
