250r/master3

Well I got a power valve cylinder that is ported for Christmas and I have some questions before I finely kick it over. I got the cylinder from east coast atv and believe it or not its Tim Farr’s cylinder that he had on his 250r before he switched to the 450 (I have his exhaust too). so do I need to change my stock jetting or is it fine where it is. Also should I put the v-force reed spacer in. I didn’t have it in on my old cylinder. Also what oil to gas ratio should I use. I normally use 40 to 1. thanks
