Hi,
It is melting out fast in Southern CO. It looks like riding up to 10,000' should be good to soon. And much higher within the month. I am on a new 2011ec300. Stock jetting was a bit rich at:
#6 slide
165 main
N1EH @ 2nd clip
38 pilot

It was real sluggish off idle, would rev to the moon just fine, but TONS of spoog/smoke

Now I'm running same, except blue jd needle (gasser kit) @ 2nd clip; 35 pilot, air screw 1.5- 2.5 turns. It is great to 1/2 throttle, then leans a bit much.

Question is: We are riding at 4-7K' now, soon to be 8k' up to 13k'. Anyone been getting one of these set up for the alpine? I know a lot of folks had big snow winters. We had a low snow winter... I've never tried to set up a 2t for the alpine.
Thanks

I have been riding between 4500-6000.

6.5 slide
N2ZW #2 or you can run N3EW #2
170 main
42 pj

I am going to go down to 38 or 40 pj. Likely a 40.

My bike is super crisp, torquey, perfect plug color, revs to the moon, and never spooges.

I have have JD red but it is a richer needle than what I have been running and I know it won't work.

2010 300

4-6000' 50-70' F

40 pilot
N3CH 2nd
180 main

Runs well but going to a 38 Pilot 178 Main so it will run even "weller".

Had a N1EH.. N3CH makes it so much more fun to ride IMO
