XJ650 won;t start now...

[rgouette]

Bike: 1982 XJ 650
Problem: Crank but will not start
What changed: This morning, I placed jumper cables on it, and for a short moment got the leads on th ewrong terminals.
Saw sparks, placed them on correctly, then the problem surfaced: no start.

ps. DOES have spark at the plugs!

;-(
Thanks,
Rich

bloWn ignition fuse, ignition fuse on some machines is on a difernt fuse from idiot lights
could of fried your CDI if you have one its possible, I dont like using jumper cables on bikes even if you get them the right way arround....your better off using a low ampage setting on a charger to start a bike than a jump from a car IMHO

[rgouette]

Could it be that ingition fuse if it does everythign except start?

thanks for the reply & I'll consider your suggestions for not using jumper cables.

It turns over and has spark at the plugs? Doubtful it's an electrical problem, if so. Looking for blown fuses or buned/frated wires is not a bad idea.

Are you getting strong, constant spark all the time?

Aye ... is it "strong and blue" spark?

Also something for everyone to keep in mind - When jumping a vehicle (ANY vehicle) it's best to place the crounding clamp of the jumper cable on a "Good ground point" of the bike or engine - instead of the negative terminal of the battery -of the vehicle being jumped-

Was the key on with the cables reversed? If not, do the checks mentioned and start looking at fuel flow issues. Has the bike been sittting? Do you have a PRI position on the petcock? If so, put it there for a few seconds to allow the float bowls to fill, and try again. Don't forget to put it back, since it's gravity feed and can cause overfilling on the sidestand.
