What to do to my yz 125?
The yz125 is probably the best 2 stroke 125 around partly because not all the manufacturers are bothering with them any longer and the likes of the cr did not do any further development on theirs after 2005. So unless you are an A grade rider and looking for more from the bike which I doubt would be the case as if you were you would be on a 250f and not a 2 stroke, then the bike should not need upgrading and should have all the power you could need. Like one of the other answerers has said ‘practice’. Learn to ride the bike standard and you will be a better rider.
