The rain killed my bike - October 6, 2010, 04:56 PM

99 SV650

So I left my bike uncovered during the drenching last week.Ran like new before and runs like crap after. My first thought was electrical as the wiring harness has been hacked to pieces before I bought it. I did some basic electrical tests to check for spark,rectifier,stator,and battery.All checked out. Used the Google to search for similar issues.Sounded like water in gas.Checked the gas cap gasket and it's probably from 99 as it's cracked.So I drained the gas...that sucked balls.

Put new gas in and let it idle for several minutes.Finally got it to idle normal with the choke off but if I twisted the throttle quickly it would cut off if I didn't let off.Was also backfiring.

Now here's the kicker...I noticed that if I moved the bike side to side the RPMs would slow down and then go back to normal when I kept the bike stable.There are 3 gallons in the tank so it's not a low fuel issue.

I drained the gas but didn't pull the carbs off.I think I read something about draining the floats.The whole moving the bike side to side and affecting the RPMs with an almost full tank has me scratching my head.

Well you see, Norm, itís like thisÖA herd of buffalo can only move as fast as the slowest buffalo. And when the herd is hunted, it is the slowest and weakest ones at the back that are killed first. This natural selection is good for the herd as a whole, because the general speed and health of the whole group keeps improving by the regular killing of the weakest members. In much the same way, the human brain can only operate as fast as the slowest brain cells. Now, as we know, excessive intake of alcohol kills brain cells. But naturally, it attacks the slowest and weakest brain cells first. In this way, regular consumption of beer eliminates the weaker brain cells, making the brain a faster and more efficient machine. And that, Norm, is why you always feel smarter after a few beers.-Cliff Claven

I'm no expert on SV's, but it sounds like the carbs need a good cleaning.

Someone else should be in shortly to elaborate on my thought.

What I didn't want to hear.Do you think I could just turn the drain screws on the floats and any water would just drain out and double rainbows would appear on the pavement?

Seriously,I figured it was a carb cleaning.I live in an apartment in the middle of Old Town and I get yelled at for working on my bike.Thank god nobody was around to see me pouring gas from my tank into a gas can yesterday.Half of it was on the ground.

Anyone wanna make a few extra bucks to clean them for me?

Make sure there isn't any water in the valve cover holes where the spark plugs are.

That was my 1st thought. If any water got down past the boot, it will short out the plug. If I am not mistaken, I think the SV is famous for this when riding in the rain.

this, the GF's 02 hates the rain, takes a while to warm it up enough to get rid of the water and ride correctly. SV's have an issue in the rain.

Thanks.Will check that tomorrow! Anything that will put off pulling apart my carbs.

Is there a solution to this? May as well knock it out while I'm fiddling with them.

There is a small hole on the right side of the front cylinder at the bottom of the head that drains the spark plug well. This hole is probably full of dirt and the spark plug well won't drain, which is almost always why an SV has problems with water. The solution is to drill the dirt out of the hole; it will be baked hard as a brick. Then clean all of the muck out of the spark plug well using compressed air and a rag on a thin screwdriver, then remove the plug and clean it and the spark plug well again. Then reassemble. The drain hole leads to the bottom of the spark plug nut, above the threads, so you don't need to worry much about damaging the head while cleaning out the drain hole.

Sounds pretty much covered by everyone else

....I was riding home from MIR in the rain last Sunday. I was drenched and my GSXR and HAYBUSA buddies all want to by my bike a rain coat.

My SV is currently sitting in the garage waiting on me to put the spark plug back in the front "jug" (haha). I intended to get it back in on Monday after letting it dry out over night on Sunday when I pulled it, but things got in my way...

Anyways when you dry out the boot and replaced the plug put dielectric grease on the porcelan part of the plug and the boot to create a seal...The bike was only running on one cylinder...it's happen to me plenty in the heavy rain...I've just never been to the point to where I couldn't ride it home and had it put inthe truck to get home from MD.


What do you value more? Life or Image?

Recheck the wiring for anywhere water could've gotten in and reseal with heatshrink.

All SV's prior to '07 have a wet front spark plug boot after being in the rain. It's real easy to fix and prevent too.

Google "my sv hates water" and the first result should be a good thread on sv rider
