I have heard that it needs to be connected to buds to set the level. i'm not sure if it is doable on the carb. but i might be wrong though.

 

If it is a carbed unit you can make adjustments for high altitudes.....what year is it?

 

OK. Ill wait for some replies and make a decision. Obviously leaning towards the pros though!

Thanks

 

It's carb'd, sorry I didn't mention that. It's an 06 Outlander 400 XT

 

Have others re-jetted, dial a carb, change air intake, etc? I'm open to suggestions, just curious to know what others have done and what their success has been.

As stated, anyone in the Denver area and know of a good shop possibly?

 

Yes I have set my 400 up for high altitude and it works great. I live in the Rockies at 3000' and ride from there up to 8500'+. If you want lots of variation in altitude without continually adjusting the carb here's what you want to do. ( gives you altitude range much like fuel injection). Go to thunderproducts.com and get either a dial-jet or an intellijet...both do the same thing but the intellijet can be adjusted on the fly, has more adjustment and costs more. I have the intelijet myself and can verify that it does work. Read the info from Tunderproducts closely and apply the principal...as I said it works. Here is BRP's high altitude spec for 8000'...
Main jet...120
Needle jet..P-0
Pilot jet..30
Set your idle jet (pilot) with bike running @ 1300 rpm (note: to get a good idle at 8000' you have to re-calibrate the idle circuit .)
If you live at 8000' and ride from there on up you may have to go smaller yet on the main..check with Lonn Peterson at Tunderproducts. ( you have to create a lean condition for the dial-jet/intellijet to work) If you have the patience to tune it you'll be happy with it. When you are real high like 12000' you might want to let more air into the airbox with 1 or 2 TPI valves from Thunderproducts as well. Hope this helps..

 

I should also mention that the stock shiftout (cutch)on a 400 is quite low about @ about 5900 rpms. Brp recomends raising that some to gain back some go at high altitude.

 

Brp has a different set of weights for 6000 to 8000ft. I had two 400s and they make a big differnts in the power.:th_smiliebanana2:

 

Thanks for the info Sgt! I'll look into it and call ThunderProducts for some more info.

Appreciate it!
