08 Cat 600 stocker high elevation setup

[sipple31]

Does anyone ride an 08 Cat 600 stocker at high elevations?

I have mine setup for sea level... but will be heading west to about 8000-9000 feet in a few weeks.

Any tips would be awesome...
thanks!

Thanks for pointing that out ProX. I should have mentioned that I am looking for a setup that is pure pump gas and long-pull friendly. Those Speedwerx specs should be the same for my clutching... but the carbs won't be the same since they are 50/50 race-pump and short-pulls only.

he will get you straigtened out, remember these motors, MOST of all the 2008 motor was meant to run on a 50/50 mix, since the 08 had a pretty decent compression ratio!!! It makes no sense to due tune a high performance motor. It defeats the purpose... But do what you have to do.

I tried him already and he pointed me towards the same tech documentation. He mentioned all I need to do is turn the timing back and jet up a few sizes... I was just hoping to find someone with an exact setup I can use as a starting point.

In a perfect world i'd run 50/50 all the time... but when in the boondocks having a barrel of race gas strapped to your back isn't very feasible. A lot of guys run the 08's on pure pump with success... i'm just trying to find someone with the data for high elevation.

2.5gallon jerry can my man! They work wonders!!!

Well I guess since no one has an exact setup for me to copy... i'll just be dropping a few grams on my weights and dropping to about 400 mains.
