Outstanding engine work for me on three H-D engines! Trusted source for the perfection I seek.

Well my bike was there for 3 weeks to get a carb tune up an timing adjustment the timing adjustment was wrong I had to go back 3 times an had to take my bike somewhere else to get it right I really thought they was the best but not 👎.just to let people know beware

It would be a constant uphill battle to try to find a shop that has anywhere near the talent/experience that GMS does.

Great people and great shop. Gms leaders the way.

I love this place, i drive out for my friend who gets all his bike work done there, they do great work, and my friend is always satisfied! The guys there are super nice and help you. I highly recommend this place, worth the drive.

Top Of The Line Shop! These Guys Really Know How To Tune A Bike In Right! Working in the service department at a Harley-Davidson Dealership, we are very picky about who we outsource any work too. The guys at GMS have tuned everything from my 2004 Heritage Softail to 2020 bikes with 131 kits and have never disappointed!

Awesome guys awesome work

They built the engine that THEY wanted. Asked for 4 and 1/2 stroke, they used 4 and 3/4. Didnt bead blast the cases, line up the intake manifold, painted the cylinders and tappet blocks without bead blasting off the old paint. The paint began to flake off the minute I started putting the engine in the frame. Gave me an attitude about the paint as if it was my fault. Overall, I wouldnt recommend them. I spent $3700 for nothing. I explained that this was a restoration, that I wasnt interested in a bar blaster, and even my new motor guy wondered how they expected me to start this bike with a stock prestolight starter. Now, I have to have the entire thing torn back down. Never again.

I dont know what GMS is.

These guy are awesome!!!Damon & Greg are the best. I will never let anyone else do any motor work on my bike again but them

Cant say enough good things about Gregg & Damon. They transformed by bike and now I have to relearn how to ride. Respect the power!

Great guys very knowledgeable and friendly

Complete in house Workshop.

Courteous, listens and explains. Will definitely recommend the shop service, if you know what you want.

Highly qualified and very personable. Its always great to see people who are passionate about their work.

Unbelievable customer service !! Damon & GMS not only fixed the horrible dyno-tune that a Pgh area Harley dealer did to my bike, but they unleashed The Beast that I knew my Vrod was capable of ! I know that the Vrod is the red headed step child of Harley, & if GMS can get the BEST out of my bike, they can dyno-tune anybodys bike !! These guys are the real deal... professional & qualified !! No lip service.. just results. I drove 70 miles to have them fix my bike. I seriously would have driven 500 miles to have the privilege of GMS dyno-tunen my baby !! THANKS guys !!!!!

They know whats up.
