My current address has me in an area where the only time you aren't changing elevation is when you are inside a building. The ride from my house to the grocery store is hilly and twisty. Took the yeti for a burn on the interstate today. Even that is fun.
The ET is strugging with the hills. The altitude is not helping either but there is no jet kit for the ET. I talked to Sportique and they said the only thing they do is adjust the idle on the leader engine. Oh well. I guess I get to have that vintage feel without actually driving a vintage.
The long and the short is, I have only been here a week but the riding is great. Couple of safety notes though. Everybody accelerates hard on yellow, well into red. Look before you go. And turns are made from the lane you are in, to the lane you want to be in. If you are turning right on the curb, don't assume the dude turning left will go from centre to centre. He is just as likely to cross all three lanes on his turn and end up on your lap. New skill sets every day...until the day you die because you hadn't learned that skill set yet.
Keep em shiny kids.

Hey Trevor,
Glad to hear you have rediscovered what it feels like to ride on roads that are so much fun, I had the same revelation in Kelowna and It's something thats not easily forgotten!
�Long live vintage motorcycles that are too tough to die...�
Every area has its own differing driving conventions. Always a heck of a shock when you are new to the area. You'll soon get used to them and then find yourself cursing like a native at the out-of-towners who don't know how to drive.
I like Edmonton, I like it a lot; however, just about everywhere else in the known universe has better riding. Seldom will a twisty road go by without my thinking I should move. It passes and frequent long motorcycle trips help to keep the symptoms mild.
All that said, please allow me to say, with feeling, "Lucky Bastard!"
PS: I think they are right about adjusting the idle mixture (leaner). The main circuit is controlled by a vacuum diaphragm and will largely self-compensate for altitude. When the BMW is up high, similar carb type, it runs fine but idles lumpy because, like yours, the idle circuit is too rich.
Should be a simple adjustment though there may be a cap over the idle screw to discourage amateurs.
Just spitballing here but would throwing in a hotter plug help with the overall power? Currently its got a CR8EB in it or what motorsport calls and NGKET4.
Whatchya think?

I wouldn't go hotter on the plug unless it was burning oil and quickly building up deposits on the plug. Too hot a plug = pre-ignition = holed piston.
It will be a bit down on power as there just isn't much air up there. It should idle fine, and be much easier on fuel once you set the idle mixture. The 2006 and up LX scoots require a special tool but I think you just need a flat screwdriver.
Sure do. The instructions for adjusting the idle include attaching a tach, setting the low speed throttle screw to 1600-1650 and then adjusting the idle mixture screw out (in my case) to achieve a 13 % CO2 reading on a CO2 tester while continueing to adjust the throttle screw to maintain 1600. Ok, lemme check, nope no tach, not CO2 reader. Guess the ear will have to do.
As to the plug, the recommended plug from the manual is the champion RG6 YC but I am using an NGK right now.

Sounds like the plug you have is fine. A Champion RG6YC crosses to a NGK CR8EB. If you are rich and famous, you could use a NGK CR8EIX.
13% CO is no big deal. Usually they want 1.5 - 2% or lower. Much tougher to sort out by ear.
Here is what I would do:
First, is it an idle air screw or an idle mixture screw? An idle air screw is usually located at the front of the carb where the air comes in. A idle mixture screw is usually located at rear of the carb right next to the intake manifold.
If it is an idle mixture screw then IN (clockwise) is lean
If it is an idle air screw then IN (clockwise) is rich.
Set you idle air/mixture screw for fastest, lean idle. As you adjust the screw in and out there will be a point where the idle is fastest. Set it on the lean side of that point.
Ride around and watch your fuel mileage. A little thirsty? Go a little leaner. Fuel mileage OK but stumbles off the line go a little richer. I usually turn the screw in quarter turn increments.
The screw is an idle mix. I bumped the idle control up to a high-ish idle and then turned in the idle mix a quarter at a time. At about 3 quarters it started to stumble so I dialled the idle up a notch and gave the the mix another quarter turn in for luck. This was all done at operating temps.
Seemed to move better off the line. Not nearly as much popping and snapping when I down throttled. Not exact I am sure but certainly better. Will see how much gas it sucks for real in the next tank or two. I have been running low test for the last 30,000 km. Would high test help or just exacerbate the problem?
Just a side note, it has always stumbled off the line. As Angelo can attest, I have killed the engine revving the bike at a stop. It was not uncommon to experience a small moment of drama when you hit the gas on green and the bike stumbles....hard. Too much juice from the accelerator pump probably.
