I'm looking at a SX viper tonight, it has 700 original miles on it he states, electric start and reverse, for $1400 bucks. The only thing is that he says it needs a carb cleaning because when you snap the throttle really quick it bogs down. But otherwise with normal throttle and at an idle it's fine. I just wanted to see if there is any other cause for concern with the issue. The price is right if its just a carb cleaning but I don't want a can of worms for if it isn't a carb. What do you guys think, if it truly is only 700 miles it pretty much should be the carbs right?

Sounds like plugged pilot jets. Have you done a compression check? And if you do don't be alarmed when the pto cylinder reads a little lower than the other two. It is normal. If it only has 700 miles it should be pretty clean.

Pilot Jets! Clean the carbs.
Just picked it up for $1150, needs trailing arms pretty bad it looks like, possibly like one of the owners of it had stored it outside because they are pretty shot. Otherwise the rest of the sled is pretty clean. 700 miles is questionable but I figure for $1150 I'll live with the fact that I'll probably never know if those are true miles. I'm thinking about checking my local salvage yard tomorrow for some trailing arms but if they don't have any I'll have to buy them over at the yami dealer.
EDIT: I also forgot to mention, he cleaned the carbs for me last night, it doesn't quite bog too much anymore, only when you get on it compared to every time you blipped the throttle like yesterday.

The first thing I would do is read Carb cleaning 101 in the TY Tech section. Then I would pull the carbs and clean them. While in there, I would write down what jets you have and needle positions.

I realize he just cleaned the carbs, but it's something that everyone with a viper or srx does preseason. You don't know if he knew what he was doing or if he did a thorough job. When you have the carbs out, I would also drain all the fuel and put in some fresh 91 or 93 (whatever your highest octane available is). If you think this sled sat outside, I would definitely clean the carb and change the fuel.

Btw... congrats on a great sled and welcome to ty.

That's a good deal. I would replace the fuel for sure as its hard telling how old it is. You can look in the classifieds on this site and find a trailing arm also. Lots of good sellers on here.
