I have a 2002 Polaris Scrambler 90...does anyone have experience with this bike? The bike runs great until my 11 year old daughter starts to climb any hills then the bike just loses all power. There is no high rev rpm, tire spin and it just bogs. I am not sure if the belt is worn or sure how to tell what the problem is. Any suggestions?

 

You might try cleaning the carb. could be something stuck in the float.

 

My daughter has a unison 90. She had problems with hills as well, quad just seemed to loose power. I ordered new clutch kit: Springs and rollers, now has no problem with hills. Not sure if this will help.

 

This weekend we brought the Scrambler 90 home and worked on it. We changed the belt, the old belt was worn down by 15,000ths. We also cleaned the carb why we were at it. Easy fix on the belt, don't know if that is the problem. Going to try it out this weekend, will let you know.
