7.48mm diameter - Includes three valve shims of each size from 1.20 to 3.50mm in .05mm increments.

141 shims in total. 0.57 cents per shim! Does your local dealer have the shims you need?

Higher pressure in the cooling system, raises the coolant boiling point and increases protection from coolant loss due to overheating.

23 PSI - 1.6 Bar.

Designed to improve the life and durability of your clutch, Barnett's "Dirt Digger" provides better rideability with less slippage compared to stock.

• Kevlar friction plates
• Tempered steel drive plates go through a vibratory de-burring process and then are quality checked for flatness to provide optimum performance.
• Heavy duty clutch springs are pre-set, shot-peened, and heat treated for performance and durability.

Includes head, base, intake, & exhaust gaskets.

Providing unbeatable performance and exceptional value, Hi-Flo is the best-selling brand of aftermarket filters for motorcycles, scooters, and ATVs worldwide.

E3 Resistor Spark Plugs

• Unique electrode shape maximizes the power created by the spark plug – Diamond Fire technology
• Electrode is a combination of performance and technology that results in an improved flame kernel shape
• This flame front ignites the bulk air/fuel mixture faster, moves heat into the combustion chamber faster and creates a more localized pressure front for faster pressure rise during the cylinder power stroke
• The result is more complete combustion and an improvement in engine performance
• A truly premium performance plug
• Sold individually, unless otherwise stated.

Keep your motor running right with fresh spark plugs!

NGK is one of the world's largest manufacturer of spark plugs, whose products are used as original equipment (OE) on countless motorcycle and automobile models.

• High-quality materials and superior construction for serious power and reliability
  • Pure alumina silicate ceramic insulator provides high strength and better heat transfer
  • Deep-seated copper core for a wider heat range
  • Nickel alloy tip for longer life
  • Trivalent metal plating provides superior anti-corrosion and anti-seizing properties
• Choosing the right high-quality plugs prevents fouling from running too cool and preignition from running too hot
• NGK plugs available for almost every application and riding style

Iridium spark plugs are made with premium quality materials.

Iridium plugs last longer than standard ones, meaning you won't have to replace them as often.

• The ultimate in the evolution of spark plug technology and performance from an industry leader
• The iridium electrode is 25% smaller than a platinum electrode, and it's just 1/4 the size of a conventional nickel electrode
• Ultra-small diameter center electrode reduces voltage requirement and extends ignition system life
• Metal shell plating has enhanced anti corrosion qualities

Sold individually, unless otherwise stated.

• Contains degree wheel, standard unit indicator, adjustable magnetic stand, and three positive stops (10 mm, 12 mm and 14 mm threads)
• Can be used to install and adjust timing of any cam
• Wooden carrying case

Made from medium carbon steel with hardened jaws. It features spanner pins and the jaws open up to 5" wide. It's ideal for holding clutch hubs, flywheels, gears, sprockets, etc. Made by Motion Pro.

This tool is designed to separate vertically split crank case halves on two and four stroke engines. Adjustable arms allow it to be used on multiple bolt patterns found on a variety of makes and models of motorcycles. Industrial grade steel construction with black oxide finish for long service life. Comes with 8mm mounting bolts and 6mm adapters. Protective carrying case included.

For easy removal of recessed oil filters.

Conical point screws pierces and grabs the metal end cap of the filter.

reduces potential damage to the engine cases.

NOT for use on re-usable oil filters.

A 3-pack of easy to apply strips measure the temperature of engine, suspension, and radiator components. Temperature range 149° to 248°

Thread Chasers are designed to clean and re-cut damaged aluminum threads.

This kit contains the two sizes most common on metric motorcycles, M6x1.0 and M8x1.25.

Thread Chasers also remove dirt and metal shavings that become captured in thread grooves.

Uses 8mm or 10mm hex sockets, a Must for all tool kits.

• 26 straight blades
• SAE and metric markings
• Check for clearance on valves, ignition points etc.
• Includes 26 blades varying in thickness from .0015"/.038 mm to .025"/.635 mm
