yep its normal, u sort out that carb prob a while back on the other 50? try setting the mixture of 2 stroke oil, does it lose power after like 30 mins riding? if so thats normal if the bikes gettin really hot.

ok, check the belt, check the coolant % it needs to be a certain percent on 2 strokes to keep the heat down, and again, check the fuel/air mixture and the 2 stroke injection mixture. Thumbs Up
