Shouldn't really go thru gas any faster, it's rich because the air is less dense. You should still be metering the same amount of gas for a given rpm. If you have problems running too rich, you could try removing the air box snorkel or lid and that should help lean things out.
And I'm looking forward to another run up there... Next time we'll make it to Banff and Jasper. Won't be this year though.
Oh good,.. I was thinking she'd be harder on gas. I think I will probably play with the airbox a little up there then.
When you do go through Banff and Jasper, you'll love the IceFields Parkway. (Hiway 93) It's a beautiful drive, and I'm hoping to do half of it next weekend. The big thing is that it's 230kms with only one gas station at 153kms (from the Jasper side). I don't plan to go as far as The Crossing, so I need to make sure I can get to where I want to go and back without running out of gas.
The Crossing is also a nice little place to stay if you want to stop for the night. The bar has a neat relaxed atmosphere where you can cook your own meals. Great for us, cos we usually roll in after the restaurant closes. We've stayed there a couple of times, once in off season and once in high season.
