1986 Ninja 600 issues....

[Cgouin]

Glad you solved your current problem. Need any parts? I've got a red seat, a black seat, a red seat cowl, and both side panels that sorta go under the seat area(same paint shceme as your avatar).

Also, an issue I've had with both my 88 the previous 85, if the bike gets wet, water actually pools up in the spark plug valley on top of the head, until it dries, the bike will misfire. If you park it outside, cover it, if you ride it in the rain, make sure it has a front fender on it(don't ask...).

ahhhhh that may have been the issue too......... it had rained and i have it outside need to order a cover for it.....and of course its pouring out now....wtf so much for another day of freedom!

as for the parts.......not sure yet send me a PM

Water is likely pooled up in the #1 plug hole. You need to prevent this from happening. I used to clean the plug boot and plug well opening, then seal it with a bead of grease around the lip when I put boot back on. You should consider oredering a new set of plug wires and caps (boots too if they are cracked).

On the side of the engine, there's a small hole, it's a drain for water that sits in the valley where the plug wires seal. If that hole gets plugged, water will not drain out, and even the best wires in the world will allow the standing water to seep into the plug holes, causing a misfire.

I want to say there's one on each side? I could be wrong, if it's only one side, I'd guess the left side.

As mentioned, cylinder #1 can be subjected to a misfire due to water buildup if the bike is on it's side stand.
Typically grease is suggested by Kawasaki to help seal the spark plug boot to the elevated lip on the valve cover preventing water from going down into the spark plug tube. I also think a silicone sealant used in moderation would be an effective method after new plugs have been installed.

I am a huge fan of dielectric grease and I think this has minimized my headaches due to electrical gremlins with regard to a 25 year old bike.
