woodland park, co jetting help

[Silver]

Just moved from Michigan to woodland park, co looking to get out and ride my 2011 ec 250. Need jetting specs if any cares to share. Thanks

Somebody down at Gunnison was recommending 5 STEPS LEANER ON THE MAIN AND 1 STEP RICHER ON THE SLOW JET. I tried this on my 300 a few years back when we went out yo Silverton. Riding 9-13,00 feet altitude my bike was lean to the point it would overheat on very long climbs so you might want to start with 3-4 steps leaner on the main and 1 richer on the slow jet.

Ran 150 main and 42 pilot on my 2011 300 riding from Crested Butte and worked just fine. Leaner on the main than I was planning on running but it was what the locals suggested.

Thanks.That will give me a place to start.

I'm riding the same elevation around Alamosa, CO (up to 13K) and running a 155 main with a 38 pilot, needle buried (forgot which needle) on my 300. My buds '11 ec300 has a 152 and a 42.

Funny, 2 years ago I drove all the way to Woodland Park to buy my gasser off a mechanic who has 2 automotive shops there (Vasholtz). He is a well decorated Pikes Peak racer (cars and bikes). He sold his gasser to me because he switched to Husky's because his son got a sponsorship by Husky. Drop by his shop, ask for Clint, super nice guy, he can give you some beta on local riding. Beautiful town, you will love it. Nearest gasser shop that I know of is Fritz Kadlec's Gunnison Motorsports. Super great resource, keeps a good amount of parts in stock. Welcome to Calarada

NEDW 2 42 pilot 162 main. Main was just based off a multiplier from my sea level setting. I'm surprised by the lean mains others are using. Makes me want to give it a try.

If you have a good needle and setup as a baseline - you can go off the derating tables in the manual.... Warning - most don't....

Well I put in a 158 main used my needle Nedj had a 35 pilot in there so left that in raised clip from 3rd position to 4th. Had a horrible bog off bottom and no power. Lean bog so I put in a 38 got better long story short I'm at a 42 pilot jet now which seems kind of rich for 8500 feet above sea level. Do you think my needle is to lean maybe I should go back to the 3rd position on my needle.

It seems on par with what others have written above. Generally the 250s like a W diameter needle, but the elevation may cancel that out a bit.

I have found though the years that I do not lean the pilot as much as the main for the elevation. Usually only one step down.
