There's an exhaust smoke coming out from PV breather tube in my KTM sx 125. Is it normal?

Mine doesn't do that. Check the seal around the power valve linkage. Must be coming through there?

My 2004 RM125 does that too. Runs awesome and never have any problems though. I've seen many other two strokes do it.
