Wet banshee

Recommended Posts

I have been having problems with my shee it's been real wet lately so lots of puddles I try and miss a lot of them but some times u can't and when I hit one it feels like my throttle is sticking wide open what's going on here. I put a new set of plugs in it drained the bowls and cleaned the filter it ran a lot better. I went for a ride to day hit another puddle and sure enough it came right back. I'm running tors unplugged, t5, k&n air filter no lid and no pre filter. Dose any one think a pre filter and one of those outerwears air box lids that Velcro on will fix this problem thanks

This is a normal banshee problem! Mine does it and it pissed me off. I run a cut out lid with water repellant material in it and it doesn't work. I also run an outerwear and it doesn't work either. I just poke around when I see the water.

Same here. It took a while to figure out b/c i figured the water was hitting my filter and choking off my air intake but the symptom was more like a lean condition. Another member on here said it and it makes total sense: When the water hits your filter/prefilter/whatever, it atomizes and displaces the air you'd normally take into your motor, so now your running REALLY LEAN and that's of course, a bad thing.

 

I have two long, wide (1.25") slots drilled down the length of the top of my airbox lid. Got a pro flow adapter for my K&N filter and bought a bunch of those stretch-on book covers from the dollar store. Stretch 'em out and spray with a good water repellant spray. Put one over your air box lid and the rest in your pocket. When you hit that unavoidable puddle, just pull a dry one out of your pocket and replace the wet one and you're good to go. Not ideal but one or two in your pocket when you know it's gonna be wet works ok. Kinda like condoms :headbang:

WRONG= if air is displaced, then you are going to be rich. If fuel is displaced, you will be lean.

You're confusing the air-fuel mixture with the volume getting to the cylinders. Yes the air-fuel is rich but you're getting less to the cylinder when you need it: the water is not compressible so you're also effectively increasing the compression ratio. This is leading to pre-detonation - dieseling. This is why the cut-off switch doesn't work to shut it off. So you automatically let go of the throttle and even with the throttle closed, the engine races uncontrollably but now without the fuel-air mix (lube) to support it that kind of HIGH RPM. The only thing that does work is to pull out the choke so the mix becomes so rich it won't burn. Think it ALL the way through next time before telling someone they're wrong.

You were on the right track in the first part of your post but

 

Water would displaces air and fuel that would normally occupy room in the cylinder since water is inert . I spray a water/alcohol mix into my turbo charged car to cool it but have sprayed straight water into the engine with little to no effect on the AFR.

 

There is no such thing as pre-detonation. There is Detonation and Pre-Ignition. Google for defintions. There is also detonation induced preignition.

If you are near water get rid of K&N junk!! Oiled 2 stage foam filter is the only way to go!!!

 

+1!! K&N's are okay and WAY overpriced, but rock a dual stage UNI and you will never go back.

I don't need to google the definitions. It was a long day. Excuse my erroneous use of the word detonation for ignition. The meaning was clear.

 

If the kill switch was off as described, the fuel is igniting without the spark plug igniting it "dieseling" there's no way to know about timing - my bad.

Had this same problem even with the tors unpluged and everything removed except the giant things on top the carbs it use to act like it was sticking wide open...weird i know!...ended up removing the whole deal with the tors eliminator kit from rmatv and never looked back...have not had a single problem with this issue..
