I'm thinkin that my ATJ pump is ready for a refresh... It was originally completely set up by Tom Papp with an A/B impeller but it's got ~ 120hrs on it now and i'm noticing quite a bit of lag out of the hole or when pulling up a slalom skier (Is 120 hrs a lot?).
Is this a 'Do It Yourself' project or should I have it done? I'm fairly handy w/ a wrench but I don't have gobs of free time on my hands. Also, any quality performance minded shops in the Bay Area that you'd recommend?
Thanks!
