How is the throttle response? Does the rpms climb rapidly when you open the throttle fast? Is there any popping or cracking coming from either the carb or the exhaust? If no popping and it accelerates with a quick stab at the throttle, then you can not be too lean. However, you may want to revisit the jetting when the weather gets hot. That is when you are more likely to do engine damage. However, if you are running slightly lean in cold weather, it may be pretty close when it is hot, since the oxygen molecules in the air are more dense when the weather is colder.
