I'm new here but also need some info on jeting.
My sportsmen 400 doesn't have the intial perk when 1st accelerating. I'd like to fixed that. Any ideas or tips.
Thanks

 

Since its a non ebs clutch,might check belt slack, should not have over 1 1/2 ' deflection,plus acceleration problem may be ramp button wear in rear clutch also. Unless machine has been sitting up and carb related due to this,jetting shouldnt be the problem if it has been running good in the past?
