91 Dies when I put it in first gear.

So about a month ago I hopped on the bike warmed it up for about 2 mins and about 5 mins later was riding down 7th street kicked it into neutral and was slowing down rear brake only.

The chain popped off, I hit kill switch, and I slowed down super quick and pulled off to the side. I noticed some damage to the swing arm, and proceeded to turn the bike all the way off and re tension the chain.

I tried to start the bike and it turned but nothing. I choked it and it fired up super quick then I put it into first, but like an idiot I left the kick stand down so it auto died.

I restarted it put it in neutral and put the kick stand up and it still died when I put it in 1st. I unplugged the kick stand sensor because I thought that was the problem and the same thing happened.

I started testing things around the bike. High beams worked first two clicks on and off but then only stayed at the regular. blinkers didn't work. heat gauge goes wayyy past H when the bike key is on.(not running)

I left the bike there for the day in the parking lot because I had to go to work. Later I came back and turned the key to see if I might get lucky and only the neutral light and oil light came on, nothing else.


TODAY
I unplugged the thermostat and the kick stand sensors and started the bike right up in nuetral. warmed it up for a little bit and then kicked it into first and it died. No kick or anything like it stalled, it just died, like a kill switch or something.


Any help is greatly appreciated.

 

I think you were going the right route with the kickstand switch, however it's entirely possible that switch needs to be closed (check wiring diagram) for the bike to run in gear. Simply unplugging it won't do, you will need to jump the wires in the lead together to simulate the switch closing ie: kickstand up

Check the wiring lead to the swith as well. It's possible when your chain jumped it ate a bit out of the kickstand switch harness. Multimeter would be your friend if you don't see any physical damage.

 

wow, in 30 years of riding street bikes i have never seen a chain come off:cower:

 

scary, I replaced the master link clip beccause I did'nt like the way the previous owner staked it. The rivits were not correct, it is your arse on the line, those master links are expensive too, but some things you can't stint on. Seen bikes toss chains on the race track, not in recent memories though with street riders. Anyway, be safe.

 

chain may have damaged the side stand switch, I just replaced a side stand and kept the wiring/switch in sitchu. You can un-plug the switch under the seat and jump the two connectors with safety wire or a piece or insulated wire and see where that gets you.

 

On my bikes that have a side stand switch, I route the wires to a hidden toggle for a crude anti-theft device.

 

^ I had the same toggle switch under my seat on my 91, until someone backed into the bike and pushed it down the driveway (it was on a hill.) The driver ended up paying for a new side stand and front fender, which got split when his bumper contacted my front wheel. I decided not to re-use the toggle and just went with the oem switch :snob: ound: :thumbsup: that chit is total classic theft deterent stuff. Cheers

 

First post here. +1 on the wiring. Safety switches cannot just be unplugged. The computer needs to see a closed circuit. I don't have first-hand experience with this bike (yet) but it sure sounds like you pinched/broke/damaged the kickstand wire.

 

The result of poor maintenance and a careless attitude.
