What is the lowest that you can run a 650sx engine at? I have a 650sx that I just bought it has 130psi in both cylinders and I want to know if it time for a new top end or can I get one more season out of it?

Gas it up and run it.

redo the top end when the cylinders vary by 10%
or it gets hard to start and wont idle or stay running
130 and even?
run her until she blows!:Banane09:
