water in engine?? need help!

[Frost]

i have a problem with my bike...

everytime i ride in the rain...after maybe 15 min of riding...the bike will feel like it's running on one cylinder (wouldn't rev up)...and it'll die eventually...especially when i come to a complete stop...

the problem is solved after the bike dies by spraying WD-40 into the sparks plug...then the bike will run smoothly again until water somehow gets into the engine...

does anyone have similar problem...
and does anyone know how i can fix it?...

Thanks in advance

If you have a cracked cover over the ignition (the "Suzuki" emblem on the right side of the engine), try painting over it with rubber cement or JBWeld (get a little into the crack).  

The next thing would be to replace your sparkplugs and see if that fixes it.  You can spray the plug and wire with a spray bottle to simulate a rainstorm.

If that doesn't fix it, you could first figure-out which side of the bike is the problem (unhook power to each coil separately and see which side causes the bike to stop running).  Then swap plug wires between the two sides and see if the problem switches sides; then swap coils left-to-right and see.

Most likely would be either the plug or the wire.

*raises hand* Doesn't JBWeld glue things together pretty damn well?  So if you wanted to take the ignition cover off, that would be sorta inconvenient

Oh, yeah!   I meant, only get it on the crack in the cover, but keep it away from where the cover meets the engine.  Better yet, take the cracked cover off and cement it with the cover off.  I took my cover off and sealed the crack by smearing hi-tack Permatex (think "rubber cement") into the crack, then wiped off the excess on the inside and the outside.  It filled the crack just fine, but didn't leave anything outside the crack.

Now that you mention it, epoxy is overkill.  Gasket sealant, or rubber cement, or silicone caulk would be fine.  In fact, duct tape on the outside would probably keep the water out

this should be under factory warranty right???

OK where are you spraying WD40 tro make it work... actually that is the very purpose of WD40... its not a lubricant, its not a penetrating liquid... its name and purpose in life is... W for water and D for dispersion... You can thank NASA for that... and remember where you sprayed it... and that's where the water is killing your electrics.
Cool.

i spray WD-40 right on the sparks plug...on top of the engine where it's sticking out...

what is the problem with it :x

should i replace the sparks plug?

The ignition cap that goes to the spark plug is the one that's letting water in and making bad connection. Replace the wire or the cap... and you'd be fine. Tell the dealer to do it... its a 2 minute job. Fritst try the cap, then the wire... wire is a bit harder... but usually you can snip a little off the wire and have it be better.
Cool.

I had the exact same problem with my bike. It turns out that the overflow line coming from the underside of the tank was connected to the carbs "vent" line. I am not sure the connection on the carbs is acctually a "vent" line but I know it isn't sopozed to get water in it. In my case what would happen is that when it would rain water would go into the gas cap area (overflow) the trickle down the line into the carbs. It also became a problem a one particular fill up. I had accedentally over filled the tank and a bunch wend down that line to the carbs. This filled my carbs up completely with fuel. Needless to say it wouldn't start until I emptied the float bowls completely.

Anyway check to see if some idiot hooked you overflow line to your carbs.
