I haven't done Pikes Peak either, since it is gravel a good portion of the way to the top. But I did do Mt. Evans (14,200 ft) on Sunday, no problems on a stock 04 Speedy. Sure you loose power at that altitude, but you won't be racing up there anyway.
We did get a little snow while we were at the summit.
Take warm clothes, and go early, the storms move in up there around noon time.
Later
