2009 yz450 jetting

Recently bought a yoshimura rs2 full system for my bike and would like to know some suggestions on jetting with this exhaust the rest of the bike is stock. with the stock system it had a slight decel pop running 93 pump gas and no pop using VP110. The jetting in the bike is stock as of now. I live in ohio which is around 1000-1500 elevation
