Hi, sorry for the topic, I know everyone hates giving jetting settings cold. Anyways, I'm halfway thru my XR600s engine rebuild, and completely forgot about jetting. I have a hotcams stage 1, intake porting and am putting in an Arias 10.5:1 compression piston, and had the head rebuilt (valves cut or replaces, seats cut) on stock bore. Previously I had a 172 main in there and it was just about right on. I know I'll have to go up, and I will buy a spread of jets. However, do you all have an idea where I should start from and go to? Thank you!
