desperately need help

[desratt]

brand new 2011 drr 50R with a uni pod filter.

won't run right . down hill it runs like a champ but on level ground it is real slow going then after a bit kicks in and runs fast. will not climb hils and starts slow on the flat.

already removed the strap on the cdi.

checked jets it had a 105 main and a 38 pilot.

put a 112 main and ran better changed it to a 120 and ran even better but still not right

any advice.

it likely needs a new spring in the rear clutch.

[desratt]

it's brand new fresh out of the crate.

Ill second that.

[selbygirl]

take one of the roller wghts out and see if it improves if that works that means your heavey on the rollers wghts does it have a slipper sprocket make shore its tihgt and what sprocket ratio you running

[desratt]

stock slipper and stock ratio.

[fomospede]

the stock setup is lame
like all have said step up a new torsion spring
since you have it in your hands some new clutch shoe springs to match!
when u are buying that stuff get a couple new retainer nuts for all 3 points
hope this helps!

What fomo said. The clutch out of the crate is trash and likely the rollers are too big. Do what someone said and take 1 roller out and see what happens. If it helps, time to clutch it up proper.
