Chain Adjustment
Proper chain tension is vital to drive-component longevity and peak performance. A chain adjustment ensures your chain is not too tight, which puts strain on your wheel and drive shaft, or not too loose, causing unneeded wear to your sprocket and gear.
Chain and Sprocket Installation

Chain and Sprocket Replacement
Your chain and sprockets are constantly exposed to extreme conditions. Due to wear and tear, all chains and sprockets need to be replaced eventually. It’s always a good idea to replace your chains and sprockets at the same time. You’ll notice a difference in the way your vehicle runs, shifts, and sounds.
Full Engine Rebuild
A full engine rebuild enhances your machine’s performance. We disassemble the engine down to the bare block and rebuild it with all new components. A full rebuild includes new parts, such as gaskets, oil pumps, timing chains, gears, and belts. You’ll get remachined valves, valve seats, and crankshafts, as well as a new air filter, fuel filter, spark plugs, water pump, and all the power of a rebuilt engine.
Hydraulic Line Flush
Purge contaminated fluid with a hydraulic system flush. Regular system maintenance removes contaminants and deposits and helps extend your vehicle’s life.
Oil and Filter Change
Protect your investment and keep your vehicle running smoothly with regular oil changes as specified by your manufacturer. Oil lubricates, cools, and cleans your engine. An oil and filter change is an easy, affordable way to maintain your vehicle and keep it on the road and running longer.
Preseason Inspection
Improve the overall operation and performance of your machine for the upcoming season. Pre-season inspection includes a fuel system, engine, oil, exhaust, and battery check. Your vehicle will leave in peak performance operation with a clean air filter and everything it needs for the season.
Radiator Flush and Fill
Promote long engine life with a cooling system flush and fill. Even in moderate climate conditions, heat and cold are hard on your engine. Clean fluid ensures that your radiator operates at optimal efficiency. It keeps your engine block at normal operating temperatures, and it lubricates expensive engine seals. Flushing the radiator prevents corrosion and costly repairs.
Recall Inspection

Shaft Drive Fluid Change
Shaft drive fluid changes are quick and keep your bike or ATV running at top performance. Stop in today.

Tune Up
Full tune-ups are available year-round on all vehicles. Keep your machine running smoothly and extend its longevity. A full tune-up includes fluid changes, lubrication, adjustments, electrical maintenance, carburetion, a safety check, an overall performance check, and everything your vehicle needs to run smoothly.
Valve Adjustment
If your machine is performing poorly, starts hard, backfires, or has a noisy valve train, it may be time for a valve adjustment. The valves are timed to the piston movement via the timing chain and other components. If your valves are out of adjustment, the motor’s intake stroke, power stroke, or exhaust stroke may stop working correctly.
Winch Installation
Winch installation affects the performance of the winch and the dredge system. A winch should be properly installed by professionals to make sure it operates at its full potential. Ensure your winch functions at peak performance; have it installed by our technicians.
Windshield Installation
A good windshield protects you from the elements while you’re out riding. Your windshield also makes your machine more streamlined and increases your speed. When you need windshield installation, come to us.
Winterization
Let us prepare your vehicle for winter. We add fuel STA-BIL® to the gas tank, fog the inside of the engine, grease the suspension and drive shaft, and spray metal protector on all of your metal engine components to fully prepare your vehicle for winter.
