PRE-OPERATION CHECKS

ALERT

FAILURE TO INSPECT YOUR ROKON PRIOR TO OPERATION INCREASES THE POSSIBILITY OF AN ACCIDENT OR EQUIPMENT DAMAGE. ALWAYS INSPECT YOUR ROKON EACH TIME YOU USE IT TO ENSURE IT IS IN SAFE OPERATING CONDITION.

Fuel tank – Check fuel level and make sure you have a sufficient amount prior to riding. Inspect fuel condition, check for debris or moisture in the fuel tank. NOTICE Using very old or dirty gasoline can cause the bike to run rough and can also clog the fuel system preventing proper fuel flow or atomization. Always use fresh gasoline or fuel that has been treated with a quality stabilizer.

Engine oil – Check the level and condition of your engine oil. The oil capacity is .6 QT of 10W30; check the level from the FORWARD dipstick/plug. Remove the plug and wipe the excess, reinsert the dipstick into the tube to check the oil level. DO NOT thread the dipstick into the tube to check level. Ensure that it is at or near the “FULL” line indicated by the dipstick. Always check your oil with the bike in a level position. TIP You can use a block of wood beneath the kickstand foot to stand the bike upright while you check the oil. Examine oil condition, very dark oil or oil with small metal debris present should be changed. Excessive amounts foul smelling, thin oil indicates a sticking carburetor float/needle and contamination of engine oil by gasoline. If this condition is present the problem should be addressed immediately.

Miter Box and Transmission oil - The miter box should have 2.5 oz. of EP 80W-90 gear lube oil. The transmission takes 6 oz. of EP 80W-90 gear lube oil. The transmission has a fill/check plug near the bottom of the case. There is no fill/check level for the miter box so measure before filling. Over filling of either the miter box or transmission will result in seal leakage. TIP A zip tie can be used to dip the miter box and transmission to determine oil level and condition.

Brakes – Evaluate the brake system by squeezing both brake levers and confirming that there is movement and adequate resistance. A spongey or soft feeling in the brake levers can indicate a leaking system, worn brake pucks, or air in the line or caliper. Inspect brake discs to make sure they float freely on the drive shafts. Stuck or seized brake discs can cause brakes to drag, overheat, lock or become noisy. Inspect brake pucks to ensure there is sufficient friction material. If irregular wear is present or if cracking or chunking of the pucks is detected they should be replaced immediately.

Throttle – Check the twist grip throttle to make sure there is minimal end play or looseness. Make sure operation is smooth and without excessive resistance. Ensure that the throttle completely returns to idle position once released. 

Drive Chains – Inspect all drive chains for excessive looseness and wear. Deflection specification, lubrication and alignment guidelines are outlined in the chain adjustment procedure in section 14. Ensure that chains remain properly lubricated and free of foreign contaminants. Note any popping or grinding noises coming from the chains as this may be a sign of an improperly adjusted chain or misaligned sprocket.

Wheels and Tires – Check for proper tire pressure (5-7 off road, 7-10 on road) do not exceed tire manufacturer pressure recommendation. NOTICE Rear tire pressure must never exceed that of the front, driveline damage will occur. Examine the tires for excessive or irregular wear. Check for the presence of foreign objects such as nails or other debris that may have penetrated tires causing leaks. Make sure that tire beads are fully seated on wheels. TIP If you suspect a tire is leaking air you can coat the tire in a soapy water mixture. Leaks will be easily identified by the presence of soapy bubbles forming around the affected area.

Battery – Verify that your battery is in its proper location and is held down via the retaining bracket. Make sure it is not sitting loosely in the frame and that the positive terminal is clear of any electrically conductive material.

Lighting – It is important to verify that all lights installed on your ROKON are functioning properly. Being visible to other operators and having a working headlight at night are essential aspects of safe ROKON operation. Check headlight, tail marker and brake light prior to operating. On street legal versions, verify that your turn signals are illuminating properly and flashing at an appropriate interval.

Drive Belt – Every ROKON is equipped with a CVT (Constantly Variable Transmission) which consists of a front torque converter, belt and rear variable pulley. Examine your drive belt for signs of irregular wear or overheating. Check belt tension for excessive looseness. Make sure your belt and CVT faces stay clean and free of foreign contaminants. Inspect for the buildup of excessive belt debris on the frame, engine and inside CVT housing cover.

Steering and Universal joint – Turn your handlebars all the way to the left and right multiple times. Verify that you are able to steer all the way to the stop points without interference from hoses, wires or cables. The front end should move smoothly from left to right without resistance, a hesitation or inconsistent feeling can be an indication of a stuck Universal joint or a failing steering head bearing.

Fairings and other hardware – Check for the presence of all covers and fairing hardware prior to operating your ROKON, it is never advised to operate your machine without all covers and chain guards in place.
