Bike help for a friend 4 Years, 6 Months ago  
I have a friend in FL who rides a '97 Kaw Vulcan VN800. He needs help and asked if I'd post this here.

He recently rode through an 8" deep puddle. He didn't know it would be that deep....

It may not even be related, but ever since he shut it down from that ride; it will start, he can drop it into first, but as soon as he begins to let the clutch out... it instantly shuts off.

Some safety switch is probably to blame, but he just cannot figure out where that might be. He's asked me to pose his issue here with you folks.

His tried a Kaw forum and has gotten no good answer.

By the way, he says the manual shows there had been a kickstand safety switch, such as we have on our R*s, but it's not there anymore. I get that, as I have eliminated the switch on both of mine, too.

But, something's killing the ignition as he starts to let the clutch out. (there's no switch at the clutch handle)

Any suggestions for my bud in FL?

What did he do with the wiring for the switch? Might check it and see if the stowing got blown loose by the water.

Good point! PO may have taped the switch closed, buried it, water might have ruined the tape and the switch is now open again!

I'll tell him to look for that.

Thanks, JD, that's some real good thinkin'!

Other ideas???

If he's able to put it into gear, and it doesn't immediately shut down, then it's not the kickstand switch. You're saying it dies when he starts to let out the clutch. Sticking brake pads causing it to snub??? Just a thought.

He says it's clearly something electrical killing the ignition, and not mechanical stalling the engine.

He can push it... it rolls.

If he holds the clutch fully in, it will stay runnin'. Only as he lets out the clutch a little ways, it shuts down.

It is liquid cooled... there's another switch related to being overheated. Maybe........

Good point. I wonder if the neutral switch is working right. Does the neutral light go out when he shifts into gear?

On those bikes it is a combination of the kickstand switch and release of the clutch lever that kill the engine. If the switch was removed, look for the wires that went to it, I believe they must be connected together to bypass the switch.

Try to bypass the clutch safety switch...if it's anything like ours, it's under the clutch handle. The clutch, neutral and kickstand safety switches share a common through three diodes in the relay that way, any combination of two will kill the ignition.

Re:Bike help for a friend 4 Years, 6 Months ago  
PO disposed of that Kaw sidestand switch on that Vulcan, but, since we have a clutch handle switch (I just went and confirmed that... never noticed before), he may well have one, too. I'll bet that's the culprit!

Any more ideas from anybody else?

Good sleuthin' and diagnosin', guys! (I'll bet we've got a winner already! )

Called him... it's pouring down rain where he's at, and it's under a cover and he'll look for a similar clutch handle safety switch a.s.a.p.

Still, if anyone else has anything else to add, it's not resolved yet. Any suggestions are greatly appreciated.

He asked me to ask you guys, because I boast so much about the Clinic to all my riding buddies. The Kaw site he went to wasn't helpful.
