As an aside from just performance, I have to give big thumbs up to G2.
A coworker of mine who just had their first kid (3 weeks old), in a semi conscious state, bumped into my parked bike with his car. Mostly everything was ok, but it landed on the throttle side handlebar and mangled the bar as well as the throttle tube. I KNEW this wasn't a warranty issue, but decided to give G2 a call anyway. They were so incredibly willing to work with me, I was blown away. They easily could have just said - "sorry, our warranty only covers mfg defects, etc," but instead, replaced my throttle tube for super cheap. I'm always in favor of supporting smaller performance parts suppliers who take care of their customers.
Even a fool who keeps silent is considered wise; when he closes his lips, he is deemed intelligent. - Proverbs 17:28
