This ever happen to anyone on Sawmill Motorway???

Thought I'd putt Ruby Clearwater up to Rock Inn then hit Sawmill over to Quail Lake area. Well I got going up Sawmill and bike started acting weird...I came to the conclusion that it was the elevation ??? Bailed out at 7n23??? before the Sawmill Campground. Just wondering if this ever happened to anyone's bike up around there. 5100 ft...

Years back I went through there on the DR-650 and didn't have any problems ???

05 DRZ-S, 3X3, Drilled OEM, FCR39 with 155-45-200-100 EMN 3rd clip...

No I haven't
That's not a dramatic change in elevation, so I'm thinking that it could be another problem of fuel delivery (ie. filter or something). Of course, you may be right at the edge of adjustment where it does affect you.
I rode from 2500ft - 8000ft with no noticeable issues last year. But my carb may be set-up different.
Don't think I've helped you, just my 2¢

Thanks for the comment...you confirmed my idea that 1000 to 6000 ft should be ok for most set-ups... I have been experiencing mid-throttle surging/stumble since I put the FCR carb on. It runs liked a raped ape when you pin-it, shift, pin-it, shift, pin-it but can't hold a steady pace at mid-throttle / mid-gear??? I'm thinking that my emn needle on clip 3 may need to go down to clip 2 and lean out my mid-range fuel mix.

Any other ideas on this surging/stumbling problem???

Thanks for any advice...

No.
I'd start with that.
Most of the time, riders make the mistake of changing too many things at once and never know which one fixed it.

Actually...I'm going to put the Yosh Pipe on I bought 6-7 months ago, back when I first re-jetted the OEM carb. Then I read where OEM pipe was pretty good for power just weighed a little more so I never installed it. Now I'm gonna see if it will lean out the mix an fix the mid-range surging...then I'll try the clip.

Sounds like a plan.
Look at it this way, more testing = more riding time.

Good luck.
