Drz jetting

My drz was bought from someone up in north west and it is now at sea level and running lean. I think its an e model. It has the stock plastic tank and thicker header. The carb is a mikuni 36mm. I can't figure out which jets to use. I think its a 160 main and 22.5 idle. I apologise for the noobishness I just got rid of my 125.
