Well, here we go again. I haven't ridden my SV in weeks, yes weeks. Due to a multitude of things, including but not limited to weather, my ride has been sitting idle in the garage. I've been concerned the fuel may become stale and I might have to schedule another dreaded carburetor clean-out.

I finally bought some gas stabilizer last weekend, rolled out the bike, dumped it in and let it run for about 15 minutes. I noticed, and have been noticing, that's becoming harder and harder to start. "Hmm, this is familiar", I thought. Despite the difficulty starting, once it was warmed up and I turned the choke off it was fine.

So, today, after over 7" of rain a 48hour period and more rain forcasted the rest of week, I decided to ride. Today is supposed to be a nice day sandwiched in between a bunch of crappy days. "Perfect", I thought. I can actually get the chance to try out my new Alpinstar GP3 boots that have been sitting in the closet for three weeks.

I get all geared up, jockey around the vehicles in the garage (no small feat) and migrate my work gear (cell phone, IPaq, ID badge etc) over to the bike. I get the bike out first off, it's having a hard time turning over. The battery isn't dead but I haven't had it on a charger so it's struggling. With FULL choke on, after about a minute of trying it starts to putter. It's idling horribly, I can almost count the time between the pistons firing. My bike is really struggling.

Mind you, it's about 40 degrees outside and the bike is cold so I expect some difficulty. Well, I don't like the way it's sounding and if I try to take the choke off it just dies. Even revving the engine with the choke on (the only way to keep it going), I can tell it's laboring.

I must have tried getting it to warm up and getting it going for 15 minutes. Even after that long, as soon as I took the choke off, it died. This has happened only one other time. When it happened last time my carbs were clogged and it cost me $250+ to have them torn down and cleaned. They said I had a tank of bad gasoline (no fuel filter on the SV), but later I realized I had let my bike sit too long without stabilizer and that was my problem.

Here's what I don't get. It wasn't nearly this bad on Sunday when I added the Sta-bil. Now, my tank was not full of gas when I added it, does that matter? The directions don't say to fill the tank. I had about two gallons of gas leftover from my pressure washer/lawn mower tank and dumped it into my bike. That didn't seem to matter either.

So, did I do something by adding the stabilizer without filling the tank? Or, are my carbs FUBAR again? If that's the case, is it something I can do myself? I don't know squat about tearing down a carb, but I'm willing to learn all winter long if it's that or $250.

:bash: :bonk: :cursin:

First question, was that jerry can you used to fill the tank, by any chance left outside during the rain. Maybe it pick up some water and now you have water in your gas. Simple yes, but i have had it happen to me before. Even with a completly sealed tight jerry can. Although it doesn't really sound like water in the gas, you never know, it could be something simple like that.

Please tell me your pressure washer and lawn mower are 4-strokes so you didn't dump premix in your tank. Also, how much stabil did you add? If you put in enough for a full tank, you could have too much in there and it won't run right. You may need to drain the tank and carbs and try again.

Do you have a trickle charger? I would keep that on it. Just sounds like its saying "too cold out for me" I would not think the stabil has anything to do with it as long as you had some gas in the tank, how much gas did you have in it when you put the stabil in?

This is one reason I say...add stabil in the tank at the gas station then fill it up!! It then mixes the stabil all nice and doesn't cause any bad mixtures!

As far as the SV thing...I'm not sure. Not to mention I don't think that your jets are going to be any smaller than say mine are...so I can't imagine the stabil messing them up, unless you poorly mixed it!

However, I think Larry is right on this one! Remove your tank, drain it into your gas can. Then remove the carb bowl screws and drain them. Take your SV tank to the gas station, put a gallon in it...shake it up and then drain it into your car's tank!! Then add some stabil according to stabil specs(if you think you're not going to be riding much) and refill your tank with some good 93 octane. This will be good and mixed by then.

Go home, make sure you have the carb bowl screws in and put the tank back on the bike! Open the petcock and allow the bowls to fill, you can sometimes hear this!

Then try to start it up again!

Pippi is right about the battery tender...but that isn't your issue right now...

Let us know!!!

wow, I can just see the shanman garage rant now!! this sounds just like what happened with my yamaha back several months ago, and similar to what happened with my Kat. now the yamaha did have some bad gas combined with terrible gunked up carbs..and my Kat, the carbs were so bad, it took them like 5 hours to clean them out! since then, its made a world of difference. Keepng the battery ona trickle charge has helped alot as well, in terms of not so much laboring when trying to start it cold.

I dont know jack about cleaning out carbs either, but this sounds all to familiar.

Not it's not premixed, I use 89 or better octane gas right from the pump.

I added 2oz of Stab-il, or four .5 oz cup-fulls with (I estimate) about 1/3 tank of gas. I believe it's a 3.6 or 4 gallon tank.

Do I have to drain? Can't I fill it up with gas and try?

I would just drain to play it safe. And if you do that, then you could install the $5 inline fuel filter!!

If its the same as the stabilizer I just put in (STA-BIL brand i think), 1 oz treats 2.5 gallons. I don't know if it would matter much, but you might have a bit too much stabil in. Gas Man, would too much stabilizer in the mixture mess it up?

Pickle, yes, I think that if you messed up the mix, you could put yourself into some problems. It may start to "gum" up...

So, is the concensus to drain the tank? How would y'all suggest adding a the fuel filter? Where? What do I buy?

Under the tank...after the petcock......just buy a inline filter that will fit the size hose that is there...don't forget the hose clamps...

Any fuel filter will do? Just go buy the smallest and cheapest one at AutoZone?

Yeah pretty much...Just make sure it can take the flow rate and it will fit your size hose. As a matter of fact, take a piece of the hose with you. Or if you want to spend the extra cash, cause you may have too much, go to the Suzuki dealer and get a filter for a GSXR....right from them! But a filter install might help this from happening again....that along with the mix it to a full tank of gas while the bike is off sitting right at the gas pump...

Pour in right amount, and then fill tank!!! The gas rushing into the tank will ensure a good mix...

lack of riding eh? Rain delay? A usual rain delay is 5 minutes. If I can't ride one day I usually can the next. Damn , if you would have stayed in AZ this fuel problem would not be happening! ;) Did I mention that I rode in most of this week?
Just blessing you with more grief buddy! I get the same thing on my KLR when it sits too long. Luckily, the carb is easy to remove and clean. I would suggest taking them off and getting to know your SV intimately. The slightest bit of residue/varnish that gets into any of the ports or jets is going to cause poor performance.
Maybe I could ride out there during xmas / new years break and lend a hand?
