Frequently Asked Questions

RK CHAIN

Q How should I maintain my non-O-ring chain?

A Doing routine maintenance on any chain is a crucial step to getting the maximum wearlife out of your chain. You should clean and check its adjustment every 400 miles (sooner if the chain gets excessively dirty). Use Formulated o-ring chain cleaner or other similar product to keep dirt from building up around link plates and rollers. You can hose off a non-O-ring chain, but be sure to use a moisture displacement product (like WD40) after the chain comes in contact with water. After your chain has been cleaned you should apply a quality chain lube. Wipe away any excess lube, so that it does not attract dirt.

Q How should I maintain my O-ring chain?

A. Doing routine maintenance on any chain is a crucial step to getting the maximum wearlife out of your chain. You should clean and check its adjustment every 400 miles (sooner if the chain gets excessively dirty). Use formulated O-ring chain cleaner or other similar product to keep dirt from building up around link plates and rollers. Don’t use a wire brush or pressure washer. If your chain comes in contact with water, be sure to use a moisture displacement (like WD40). Lubing an O-Ring chain is vital for maximum wearlife. All RK O-Ring chains are injected at the factory with a lifetime supply of internal lubricant. The purpose of an O-Ring lube is to keep the chain from rusting and the O-rings from drying out. We recommend RK special formula O-Ring Chain Lube because it is a non-aerosol, specifically formulated to stick the chain, yet not attract excessive dirt.

Q. Will I need any special tools to install my new chain?

A. We recommend that every RK Chains be installed using a chain tool. Some tools, like RK’s UCT4060, combine all the parts needed to break the chain, cut it to length and clip or rivet the connecting link.

Q. Can I use a connecting link from a different type of chain?

A. No, you should only use the connecting link for your specific chain. If you have lost your connecting link please contact your dealer for a correct replacement.

Q. Is it OK to add links to a chain if it’s too short?

A. RK does not recommend adding links to a chain if the chain is too short. You should purchase the correct length instead.

Q. Does RK or Excel sponsor riders?

A. Yes, Both RK and Excel sponsor riders of all levels. Most riders submit their resumes in September/October. You can also send your resume through Sponsorhouse.com

Q. Where can I purchase half-links?

A. RK stopped producing half-links ten years ago.

Q. Is it normal for a new chain to stretch after the first few rides?

A. Yes, it is normal for all chains to stretch a small amount. You should adjust your chain alignment and tension to OEM specs for your motorcycle/ATV. Check again after the first 50 miles and again after 200 miles. If you are riding off-road, check the chain before every ride.

EXCEL RIMS

Q. How should I clean my anodized rims?

A. Rims that have been anodized require special care. DO NOT USE SIMPLE GREEN® ON ANODIZED RIMS! Wash rims with a PH balanced soap (shampoo) and rise thoroughly.

Q. My rim has small cracks near the nipples, what caused this?

A. Cracks around the nipple holes indicate over-tightening of the spoke and nipples. Nipples should never be over tightened. We recommend using a spoke torque wrench when lacing your wheels. Excel produces an adjustable torque wrench designed to tighten your nipples to the appropriate specs. See the Excel section of our website for details.

DOUBLE ROW WHEEL BEARINGS

Q. What all is involved when modifying the Universal type Bearing Kit to my bike?

A. The Universal Kits require a modification to the stock spacer and speedo drive. You need to machine off 200 thousandths of an inch off of each piece.

Q. Is it normal for the bearings to “weep” grease?

A. Yes, the bearings are over-packed at the factory. This is a normal occurrence with Double Row Bearings.

Q. Will I notice a difference ride-wise after I install the bearings?

A. Yes, you should notice a smoother, more fluid ride and that all wheel wobble associated with Timken style bearings will be gone.

“The first thing I noticed was that my wheel wobble had stopped and that I actually needed to apply the brake when I was waiting at a stop light. The ride is so much smoother now.” Craig Murrow, Hot Rod Bikes

EXCEL PRO SERIES WHEELS

Q. What are the benefits of the Pro Series Wheel?

A. Unlike OE-type hubs, Excel Pro Series Wheels can be moved from one bike to another by using bike-specific carrier rings. This feature saves you hundreds of dollars by allowing one set of wheel to be used on several bikes. Pro Series Wheels are lightweight and are available in three different colors: gold, black and silver.

BENDIX BRAKE PADS

Q. What is the difference between the sintered and ceramic brake pad compounds?

A. Ceramic brake pads are designed for non-competition general use. Sintered brake pads are specifically designed for racing purposes. Ceramic pads provide consistent stopping power yet are designed to be “easy” on OEM rotors. Sintered pads have a high coefficient of friction to provide high initial bite and maximum stopping power. Sintered pads are generally more expensive than ceramic pads and typically wear faster than non-competition pads.

FRAM FILTERS

Q. Will using a FRAM Filter on my new bike void the warranty?

A. No, FRAM Filters meet or exceed OEM specifications and therefore will not void the manufacturers warranty. FRAM Filters trap debris smaller than 10 microns (1 micron is smaller than 1 thousandth of a millimeter)
