Looking for help with 1999 Summit 670X Twin Pipe question, PLEASE HELP!

[massey.ross]

Hi, I'm new to the Snowest Forums, and was wondering if any of you guys can help me out.

I just recently purchased a 1999 Summit 670X from a family member in Soldotna, AK. The sled has Team Fast Twin Pipes, a carbon fiber rotary valve, and some clutch work done to it. It also has the stock altitude compensator on it. The sled ran very well with this setup between 1-4k elevation in AK.

I would like to run the sled as I purchased it here in my home riding area of Wyoming/Montana, at approx. 8-10k elevation. However, many of the folks that I have talked to around here have told me that I will burn the motor down with the twin pipes at this higher altitude. Is this true? Does anybody have any recommendations/advice? If I do need a single pipe, etc., does anyone have one for sale, or know where I can find one? What do you guys recommend?

Thanks in advance! I look forward to hearing from some of you guys!

I'm not sure they will burn it down, but from all the research I've done on these sleds, the word is they run better with a single. But I don't have any hard evidence. I have the same sled and run at the same elevation and the single does just fine.

PM Dickie on here, he has the following thread, he probably has a single he'll sell ya!

If your jetted correctly there is no reason it will burn down. However, a single STOCK "X" pipe is very tough to beat and alot easier to tune. I would keep an eye out for a stock pipe.
