5000-7000 ft. above sea level (jetting)
I'm racing the VC grand prix and the elevation range is from 5k to 7K ASL & I'm looking for some help in setting up the bike. It's an 06 EC250. I checked the jetting chart but couldn't find anything jetted for those high elev. There's a 42 pilot and a 175 main in there now I have been riding from sea level to about 3000 ft. & the bike runs perfect.
Thanks Any of you other Gasser's gonna make that race ? |

Your pilot is probably fine, but take a size 40 with you in case the airscrew is not enough. If you are hard on the throttle, then I would probably start with a 172 mainjet. Otherwise I would drop to a 170.

Thanks for input, do you think there would be any reason to change needle position when putting in the diff. size jets. I am not going to have any time to experiment before the race so thats why I'm trying to get as much info. now
Thanks |

OK, I say go with the following.
40 pilot 170 main I don't know which needle you have, but if you have any spooge dripping from your pipe, go ahead and raise the clip 1 position. To me, that would indicate your running a little rich based on the types of trail we have in NorCal. Enjoy you EC200. That's what it's going to feel like at that elevation.
