engine flooding

[Michael Grimm]

it was this past weekend at sycamore creek, the wash is flooded and mostly shallow, I saw everyone crossing it, the place where I crossed, was deeper than I thought, my whole back end sank, and ended up sucking in water through my open air box...

didn't even attempt to start it, I knew my box was flooded, luckily for me, my buddy was riding his buggy, and I had my tool bag with him, stood the quad straight up, removed the air box, removed the spark plugs, let the whole thing drain out, and set it back down, and proceeded to kick it, for about 30 minutes...and I mean not literally kick it, but pump the kick start to remove the remaining water, and YAY FOR STARTING FLUID SPRAYS! after about 15 minutes of trying to start it, it finally fired back up, and purred like a kitten, while spitting the remaining water out of the exhaust.....lol... it actually ran fine, we started a fire and I dried out my filters, put them back on, and it ran like it was never flooded...

we ended up meeting up with a bunch of other friends who have banshees and more mechanically inclined than I, most told me it would be fine, 1 told me I should rebuild the engine. another said my pistons are rusted, All I did when I got home was sprayed wd40 in the cylinder walls through the spark plug holes to prevent moisture.

I want to make sure my bike runs the next time I take it out,
as far as it being flooded, what are the damages that are possible? Even though it started up fine and ran without any problems the rest of the day, I just want to see what I need to do, and hope no damage occurs while it just sits till I ride it next.

Man, I hate to say it, but if it was me, I'd do a topend on that thing. Cheap insurance in my book. Just think of all that grit that remained in your ports, etc........
I wouldn't even start it again, until it's rebuilt.

If the bike starts and runs well then don't worry about, yanking the top end apart is going to be a huge waste of time and money. I have drowned my fair share of engines in my life and as long as you don't hydrolock them and bend a rod you shouldn't have any problems, you did ride it the rest of the day with no issues so I wouldn't worry.

as long as it didnt hydralock like the other one said your fine, and as long as you know there isnt sand or anything in there your fine. As far as rust and all that, If you ran the quad after it happaned and actualy rode it a little all traces of water that might have gotten into the cylinder were gone when you ran it. Also if you sprayed either (starting fluid) in there that to also takes up some water, so if it ran the same after as it did before then i wouldnt take it apart, unless you have alot of extra time and money. Sounds like you did all the right things to drain that thing out.

Maybe you already have, but I would do a couple of filter/oil changes to flush anything that might have found it's way in.

well its a 2-stroke, oil mixes with the gas.

last night I dumped the rest of the gas (less than a quart) filled it with fresh gas/oil mix, throughly sprayed down the carbs with carb cleaner, and it started as usual, and sounded fine, rode it around the neighborhood a couple times and nothing seemed wrong.

so hopefully itll just be fine with nothing to worry about...

anyone know about 2 strokes?
I know a little bit, but not that much...
am I running too lean? Ive been told its running lean with this setup.

I'm running
280 main jets
27.5 pilots

I mix in POWERPLUS synthetic blend oil
50:1 ratio

and I have the prodesign filter (open airbox) with bills pipes

Doh! Forgot we where taking Banshee.

I'll shut up now....
