Jetting Stock 400ex going to St. anthony

[thomps6s]

I am going to St. Anthony for the first week in April. I have a stock 400ex with a slip on HMF pipe. No other mods. I am currently in Minnesota and was wondering if anyone has run this setup out there and what jettting you ran/run. Any help would be appreciated.

I don't want to hear, "Dude, do a f&*kin search this has been posted a billion times"

I have searched and haven't found anything. If you don't have any positive information, don't reply. thanks.

Well if you are close to the same elevation you should be ok. I am not sure what jetting you will need but just take a bunch of different jets with you when you go. The elevation is around 6000 there.

I got this off a government website. I am at 1300-1400 elevation and St. Anthony is 4966 elevation.

Well my 400ex isnt as stock as yours, but I run a 170 main, stock pilot, needle second clip position and I ride ST. A's all the time..I only live an hour away..Mine runs great out there..I would bring 155-170 Mains with you and just go from there, but I am sure a 170 would be just fine for you..

Thanks for the info, I will grab a few jets to bring with. That is exactly the info I was looking for.

We are going to be out there the first week of April. It is the only time we can get together and go. Is the sand going to be wet or hard or will it be okay?

The sand will probably be went in some in some places as there still is some snow out there right now, but only time will tell by the time you get here..The snow here is melting rapidly, but I would say there would still be some snow and some wetspots on some places where the sun doesnt shine that much (shaded areas)..It will still be a blast though..
