I have a quick question about jetting. I have a 250 trailblazer with an RCR stage 1 kit on it. where i normally ride i am at an elevation of about 210 feet. next weekend i am going to ride at about 1620 feet. i am wondering if i should re jet and if so which way. the last time i was there my machine bogged when it got hot but it was also about 100 degrees that day and mine was jetted for lower temps. so im just tryin to decide what i should do b4 this weekend. thanks

when its hotter out or you go up in elav. you go leaner(down in jet size) as the air is thinner causing it to use more gas then needed making it run rich and bog down.

 

thanks for the help i always mix up the elevation.......that makes a little easier to rember with the thinner air. i found my chart and it says that from 0-3000 feet it should be the same......do u find this to be true or not.....should a go down 1 jet size anyway? thanks

it really depends on how its running. you would be a better judge at it. if its really bogging out its either too rich or the clutching is off,but at that low att. i would guess it might be one step too rich. checking the plug will be the best sign to go with.
