Will be riding through rockies from vancouver to toronto and my ride is a '94 900rr fireblade mod to a streetfighter.
​


it is carburated.

i was told there may be issues once there is that much altitude change.

should i be concerned?

any advice would be appreciated
 
My 2002 FZ1 is carbed and I had no problems riding in the Rockies last year.
 
Im going to be riding the rockies aswell and my bike is carburated. I had the same concerns and have been told there will be a minor loss of power output due to less oxygen in the air at higher altitudes.

Cheers,
Geoff
 
On a bike that powerful, you won't be lacking enough power for it to matter.

Exactly. I didn't have to push the FZ1 up a mountain once and you get to roll down the other side anyway. Mind you I was in the Colorado Rockies and our Rockies are better :-)

I also didn't suffer from altitude sickness - though the views will take your breath away.
 
It's one thing if it's a well cabureted bike that has decent power delivery but the CBR900's carburetion wasn't well matched to it's head/engine. Your trip won't pose any big issues but whatever flat spots in power delivery will be somewhat magnified. This effect could range from a small stumble off idle to a feeling that your air filter is clogged. It will pass as you descend to where there's more air at a lower altitude.
You should get on BCSPORTBIKES website and see about some roads on the way to Vancouver. Good stuff up the valley and down to Princeton from Merrit. You can go on the old highway up to Spence's bridge, then make your way to Cache Creek and Lillooet, Pemberton then Whistler. It's a 4 hour detour that will be one of the most magnificent rides that can be taken on a motorcycle. The Duffy lake rd is a rollercoaster that shows so much of what BC is! I miss that riding!
