I'm planning on doing a top end job on my 99 KX 125 soon. It is on its second one already....do I need to get an oversized or standard sized wiseco?? thanx!
With the Wisecos I believe that the "oversized" piston is the 2mm over. You'd be hard pressed to fit that in your stock bore :confused: . The standard one is the one you want.
Also, your bike is scheduled for a top end about every 20hrs. Being on your second one in 4 yrs isn't uncommon, and is probably a little past the regular service interval. Of course, it all depends on how much/how hard/and where you ride it.
