I have an 05 Sportsman 700 efi with EPI clutch kit. Question is if I have it in low and hit the throttle some times it will stand straight up and other times it barely comes off the ground.

What would cause this. I do not do it that often but of course I was showing someone the new clutch kit and how much low end power it had and 3 out of 4 times it wouldnt come off and 4th time it stood straight up.

Just wondering what would cause this

thanks

 

tires spinning?

 

not that I know of but I did it on grass so guess im not really sure
