Sounds good, this time I put some thread lock on it and really cranked down on the screw. But will keep an eye on it since it's still very new.
I used Byron's 20% fuel and the OS RP7 plug in it. I used the stock plug for the break in process as described on the Werks website. But then switched to the OS on tank #8. It worked great!
