Here are some pictures of a top end refresh we recently did on a CRF450X including a Vertex Pistons piston, Kibblewhite Precision Machining, Inc. valves and springs, and a nicely refinished cylinder.

Early Honda Unicam engines are notorious for valve wear and we do many of these jobs every year. These Kibblewhite valves are a solid cure for this and should make for years of riding before they’ll need touched again.

Give us a call for all your engine building needs now matter how big or small!

This Pro XP came in for some critical pre-season maintenance including a worn out secondary clutch. While it was here, we couldn’t help but notice the ride height was very low due to sagging and collapsed factory tender springs. We repaired the clutch with new OEM sheaves, and massively improved the ride quality with a full set of MTS Off-Road dual rate springs. And with the color matched powder coat from Jakes Kustom Kuttings, this spring kit looks just as nice as it rides.

Give us a call today to make sure you machine is riding as good as it can be before your big rides this summer!

We are excited to be working with MTS Off-Road to offer the highest quality suspension components and deliver next level ride quality upgrades to your machine.

These true dual rate spring setups are a night and day difference over any stock springs. You’ll notice a massive improvement in the big whoops, small chatter bumps and aggressive cornering.

Give us a call today to talk about how we can make your machine feel like it’s riding on clouds!

We know the worst part of a day of riding is when all the fun is over and you’re left with a filthy machine. Dust, sand and mud find their way into every crack and crevice making it seem impossible to get that showroom shine back.

Worry no more! Your favorite place for precision powersports repair is now offering detailing services with the same level of care and cleanliness we apply to all of our work.

Give us a call today to talk about the different services and packages we offer.

After hours clutch service we knocked out tonight!

After blowing a belt, it’s important to inspect and clean up your clutches to make sure your next one lasts. This machine had pieces of belt wedged behind the primary and inside the secondary.
