sv front spark plug is not firing

im not sure if it's the plug or the wire, but the end of the plug wire used to make a popping sound when i ran it with it unplugged from the spark plug. it either doesnt make that sound now, or i couldnt hear it.
the spark plug looks old, but i have no clue how old. it could probably use a replacement anyways.
sooo... im hoping that someone knows a great way to fix it.
its not water in the front cyl like i had originally thought. i took the plug out and ran the engine with the front plug out, to blow out any precipitation like i have done in the last 2 times this has happened. it didnt make any change once i got it all back together.
another reason why i think this is a plug/plug wire problem is because when i rode it with a flooded front cylinder, power could be iffy. it would go from half to full power at random. this time is different though. the front is dead and stays dead.

this really sucks because my wife and kids are in the car, at my parents house, where we were going separately so that among other things, i could do some work on the bike for fun while we were there :P

the spark plug boot screws on to the wire.
the wire should have a knurled nut that holds it into the coil.
Check if you can, that both of the small wires are still attached to the coil (primary wires).

Have you ridden the bike in the wet recently? Gen 1 SV's were notorious for no spark in the front when wet. The gen 2s actually got a splash guard to help prevent this.

Remove the front cylinder rubber cover, stuff a paper towel in it to remove the moisture, spray a bit of wd40, put back together and seal with some silicon glue.

the front plug is prone to get water in it from tire spray and collect and stay there, common problem, it did in our's also. alot of peeps made like a flap to keep it outta there. constant battle if you commute.

Not if you seal it.

As stated by everyone take a look at the wire and boot.
Also lift the tank and look at the front cylinder coil, it's on the lh side of the frame right below the air box. Make sure the 2 wires are plugged in. It's pretty common to knock one loose if you were in there.
If you wind up needing a wire or plug, I think I have a used one. Just give me a call Wed. when we reopen.

i'll try and check it out tomorrow.
im pretty certain its not water this time, because i cant hear the spark plug wire clicking when the engine is running.
also, i just found out tonight that my engine cut off switch doesnt work anymore. wtf. related?
i did see the coil when i went into it a couple of days ago, but i couldnt figure out what needed to be done and didnt want to break anything.
thanks for the replys

also, once again, i might be getting a house soon! i have money to put down and we just looked at a charming little thing in montgomery today no garage, but lots of shade trees and space for a garage
