UTV Repair & Service in Washington, Utah

MST Motorsports diagnoses and repairs Polaris, Can-Am and Kawasaki side-by-sides in Washington County, from check engine lights and power loss to unusual noises and handling changes. Modern machines run electronic fuel injection, power steering, multiple drive modes and sophisticated suspension, so an accurate diagnosis is what keeps a repair from becoming guesswork.

For Polaris and Can-Am we run OEM factory scan tools — the same diagnostic access the dealer has on those platforms. Live ECU data, calibration and service routines, and fault information that generic OBD scanners cannot read on a side-by-side are what narrow an electrical or fuel-delivery complaint down to a single part. On other platforms our technicians use powersports diagnostic scan equipment alongside hands-on inspection. See our equipment & facility for details.

Our repair and service work covers engine diagnostics, drivetrain repair, axle and CV joint service, cooling system maintenance, brake service, and steering diagnostics. We work on trail machines, dune runners, work-side-by-sides, and everything in between.

The CVT clutch is the hardest-working assembly on most side-by-sides, and sand riding at Sand Hollow holds the primary and secondary clutches under sustained high-RPM load. That heat is why a new belt on its own is usually only a symptom fix.

Our clutch repair, service, and CVT tuning covers clutch weight adjustment, spring rate changes, helix angle setup, belt replacement and deflection checks. Setups are matched to your machine, tire size, elevation and riding style, because a calibration built for sea level behaves differently at Southern Utah elevation and temperature. For Sand Hollow riders that means a setup aimed at cooler belt temperatures under sustained dune load.

Belt and clutch inspection intervals are set by platform. The Can-Am Maverick maintenance schedule published by BRP calls for a 50-hour severe-duty belt check on the Maverick X3, and sport Polaris machines carry their own hour-based intervals in the Polaris RZR maintenance schedule. For the mechanism behind a failed belt and the warning signs that come first, see why UTV belts fail at Sand Hollow.

Our in-house shock repair, rebuild, and service covers Fox, King, Elka and Walker Evans on our own bench in Washington. A rebuild includes seal replacement, fresh shock oil, internal inspection and re-valving where needed, with valving matched to how the machine is ridden and loaded. Desert sand and dust wear seals and contaminate shock oil faster than most owners expect.

Our UTV suspension diagnostics and repair covers A-arm inspection and replacement, radius rod condition, bearing play, tie rod and ball joint replacement, and UTV alignment correction for machines that dart or wander. Slickrock and sand load bushings and bearings in a way pavement never does, so wear items are evaluated as a set. If the machine carries a powersports extended warranty or service contract, we can document the failure and submit the claim to your provider.

MST Motorsports traces electrical faults on modern side-by-sides with powersports scan equipment and circuit testing. Fine desert dust works its way into connectors, sensor harnesses and control modules, producing the intermittent faults, limp modes and no-start conditions we see most often on machines ridden in Washington County.

Our factory-trained, certified technicians perform complete UTV electrical diagnostics, wiring repair, and accessory installation across Polaris, Can-Am and Kawasaki platforms. Accessory wiring for lights, winches, communication systems and aftermarket electronics is installed on properly grounded, properly protected circuits so the machine stays reliable.

Street-legal conversions run through the same bench: headlamps, tail and stop lamps, turn signals, plate light, horn, mirrors and an illuminated speedometer. The full equipment list is set by Utah Code 41-6a-1509 — see Utah street-legal ATV and UTV requirements for what the statute specifies, including the tire height and seat height limits.
