It could be one of two things..either your jetting or you have an exhaust leak. Make sure you check where the silencer and the header meet. This connection must be tight.

I agree. You either have a leak or your jetting isn't right. The Sparks is a one piece exhaust though so it would leaking where it connects with the head. Make sure that is tight.

Could it be that your carb boot is leaking from either being loose or cracked causing it to be lean?

so u think i could just be putting the exhuast wrong

There is a possibility it isn't seated correctly at the head. I would take it off. Put a fresh gasket in(make sure the old one is out of the head) and tighten it well and double check that your carb boots are tight and not cracked anywhere. If that doesn't fix it I would take it to a shop and have them diagnose it for you. Good luck.
