Hi I have a yz 125,2004,it boggs looses power when you corner when racing then it clears itself and seems OK what's wrong,is it clutch,or carburator??

Many thanks

Float bowl hanging? Fuel pickup tube?

Clean exhaust power valve and check adjustment

Clean or buy exhaust power valve.. I had to do the same to my kx125... try cleaning them cause they can't be $$$$$$$
