I just gapped my rings for my 01 YZ250 las night, I had to file them down a little just enough for the 0.16 filler gauge to slide in. Any feed back from you is much appreciated.
Heres a question for you, so I've just had my Yz125 cylinder replated with recessed exhaust port bridge and sized correctly to a wossner forged piston that has the coating, ive asked because wiseco say to drill their pistons and if you ask on forums you get everyone's opinions and you leave with as much knowledge as you started. I'm currently waiting to hear back from wossner, plus this piston is only for 91-93 so I would assume they would come drilled if needed as its all the same cylinder for those years, whats your thoughts and yes the pistons are a work of art I agree.
