I have a question just learning so you great motor head guys can helpme out.
I was running my yfz 450 in central PA. Weater was around 45 - 50 degrees. Everything seemed to run good. We went to georgia last week for the wpsa. Quad ran ok not great weather upper 70's, Sunday came & everytime I came to big jump & gave it more throttle it would bog out on me, especially in 2nd & 3rd gear. Should I have switched to a different jet?? Smaller ?? Bigger?? Just wondering so for next time to try this out. I know pretty soon warmer weather will be effecting my quad in PA.

Thanx WADES DAD

Elevation, temp, humidity go down a size posibly 2.Georgia isn't much different than us elevation wise but the temp and humidity mean alot. might be able to get away with just adjusting the fuel screw but, I doubt it.
