120 main 42 pilot here too in my stock 04. Possible Benny , wouldn't be the first time an early bike came with a part that later needed to be tweeked to get it smoothed out.

My opinion is Brent should make good on the jets since he sold the pipes then Brent should take it up with the manufacturer if he wants to.

As far as then ordering the right ones from Brent , should have gone to a local shop and got a set for $3ea jet.

I learned all I need to know about life by killing smart people and eating their brains.
