Hey Adam,
How's things in good ole US OF A. Well them engines are still running strong. I had guys think I got a new engine because of it power, it is still kicking butts on straights and on the track. The ninja and OS 25 are still a beast and don't want the kick the bucket. As you stated a tune, maintenance, good customer support goes far.
I rather have you working the engines and providing technical expertise over the phone than staring at the computer boosting business.
