Very talented shop. Amazing knowledge.

Been Working With engine dynamics for years, very honest and very helpful. Mike is always willing to take 5 minutes out of his day to look at what ever I bring in. He has done work to many of my engines and been able to work more than a few miracles.He is not the cheapest, But he is the best, and if he does it it will be right.

Back in 2008 I brought my bike here and the service was top notch. If I still lived in the lovely Bay Area Id go back!

Great work super kool people

Amazing service, decades of experience & knowledge- and not just your grandfathers machine shop! Porting & machining better than any factory.

BUYER BEWARE!!!!!!I was very disappointed! They cracked my performance head when pressing in valve seats and sent it back to me which cost me $850 and the head was useless I sent it back to them and pointed it out. he repaired it and charged my card another $240. When i called to ask why he charged me he was extremely rude and unhelpful and denied cracking it and giving me every excuse in the book?? The head was not cracked before sending it to him, and cracked when it came back. I would highly think twice before using this shop. Very shady person to work with and there are alot of good shops out there that are honest!BUYER BEWARE!!!!!!!

Great service great work and good guys!
