we have a 99'trailbalzer 250 and when I get like maybe a foot and a half of air it bogs down really bad.. I am a 235 puond rider but I dont think that it should bog down as bad as it does. any suggestions

 

This is just a guess, but it may be when the wheels come off the ground the clutches shift out and then aren't backshifting when you need power again. Check the preload on the secondary clutch, the spring may just be fatigued from age.
