yes they will prolly even out when it gets warm

 

It a 98' kawasaki prarie 400 2x4 we keep it at my house cause everybody rode it over there when we weren't there and it got messed up..(hope my rappy is safe too) but its had some probs and were thinking of trading it in for a grizley (if thats how u spell it) ..we have 2 of the same praries and one has a prob in the clutch so ill be fixing that next.. But i thought it would be easy to stop the backfiring but i dont know what to do.
