reliable repair shop in So Cal

Hey there, I am looking for a decent, reliable ,repair shop to fine tune my daughter in laws motorized bike. I put a new clutch shaft and accurater, and we got it running, but it need some fine tuning. She lives in Long Beach Ca. So anything in that area. Venice is too far. She has no other wheels or way to pick the bike up. I can drop it off, but not pick it up. I am leaving for Seattle this week. I thought I heard of one in Huntington Beach Ca. Any help will be greatly appreciated. Thank you.

OK, will do and thank you very much.
