Elevation Change Backfire
Posted October 24, 2005 - 09:59 AM
in the woods at higher elevation.
Iwent to a race in the desert at lower elevation this weekend and the bike was backfireing at most hard shifts under acell.
I know i need to change the jetting,however i don't know how to tell what
size is in the bike now. If I take the jet out will the counterman at the local
dealer be able to teel me what size it is? If so what direction do i need to go?
I will be riding in higher elevations later this season,but i don't want to damage the carb or engine by running the wrong jet size when i ride desert.
Some of our rides will start on desert floor and ride to the tree line
is there a size that could work for both?
I'm sure this subject has been posted before but any help would be great

FYI--you mentioned "jet" and not jets--there are a few in the carb plus the needle. So, you may have the swap out more than 1 jet and/or adjust the needle clip position.

Elevation does effect jetting. Depending on how "high" you climb depends on whether or not you jetting should change.
