So i've heard that the Yammies have some trouble when doing some POW turns... apparently they tend to bog out, doesn't get gas when its on its side? Is there any truth to this? I bought a 2003 MTN Viper that i intend to take out west riding this yr and just concerned about this myth. Anyone know anything about this?

My buddy has a 2001 700mm and he can pull doughnuts on the side of the mountain like nobody else i have every seen i never have i herd that he does get any fuel when the sled is laid over. That being said there may be some different fuel system on the viper. JM.02
Go out, start your sled. Tip it on its side. I'll bet it runs. 
its not a fuel issue, its a breathing issue. any brand sled will do this if you plug the exhaust outlet or extended periods. long, right side pulls in deep powder will create a bog condition. some people with piped vipers experience a bog under certain conditions where steam vapor from snow hitting the pipes chokes off the air intake. and there are several remedies for the situation. not an issue really.
I found that when I was jetted fat,,,,,it did this, if I was jetted correctly, no issue
Okay, well i DO have my viper piped, so what kinda "remedies" are there?

no idea on a viper...here is my Nytro...never a breathing problem...
except me out of breath...
Well one remedy I have seen is they put a J on the pipe so it exists to the rear, not straight down. That is one I have seen. On another one they just put a 1 inch plate in front of the pipe exit. that seemed to work well the guy said. Thats the only ones I have seen.

Looks like fun, where is this at?
Yeah, the MTN vipers have a plate in front of the exhaust exit hole to keep snow away. I'm sure it will all be fine.

heres my remedy..check out the side of the black sled
Thats handy. I like that.
Are those lighter support bars helpfule? How much weight did you lose?
Also anyone know if someone has converted the front of those to a A arm set up? So you can get rid of the support bar?

those are called trailing arms. you can loose up to 10 lbs or more over stock depending on if you go chromoly or carbon fiber. no reason to convert to a-arms.
Well if you say there is no use for A arms think of this.. If you can lose 10 pounds or more by changing them out. How much can you lose by taking them off. Minus the weight of the A arms. Also I am sure it works better when you are boon docking and you run over a tree. I have seen a few people get things wedged in that area and it is hard to get it out. I bet you would be able to increase you width easier with out them. Hmm I will have to check into that.
OKAY...i think my thread turned into "How to make the Yammies lose weight" now. LOL
Arfrce -- I think your idea of losing the trailing arms is a good idea if it's possible, things do get caught up in them, but at the same time, it's what makes them rigid. As for adding width... If your riding in the mtns you don't want width ( easier to maneuver when narrow ). I would think that converting to an a-arm set-up would not be cost effective, better to just put on the lightweight trailing arms. But thats just my 2 cents
