III. MAINTENANCE, ADJUSTMENTS & SERVICE PROCEDURES
1. Notes & warnings
Use caution when working on or around motorcycle.
Note that exhaust, engine, cooling system and brake parts may be
extremely hot after operation. Be very cautious of moving parts, especially the chain and sprockets which can draw clothing,
hair and fingers into sprockets, chain guard or chassis causing severe injury
.
Do not operate motorcycle in a confined area as
exhaust fumes can be fatal.
This motorcycle is not equipped with a spark arrester and could discharge sparks from the muffler
which could ignite any nearby combustible materials causing fire or explosion.
Do not use gasoline or other highly flammable liq-
uids to clean parts or air filter. Fire or explosion may result. Mix gas and fuel motorcycle only in well vented areas free of
sparks or flame. Note that gasoline fumes can travel long distances along the ground and readily ignite
. Safety glasses are nec-
essary whenever working with oils or chemicals, whenever impact tools are used, or when tool breakage would result in flying metal
fragments. Any mechanism with a spring has the potential for flying parts and eye injury. The rear shock is charged with nitrogen
gas under very high pressure. It is not serviceable by the owner. DO NOT disassemble or discharge shock absorber. Use hearing pro-
tection to guard against exhaust noise, realize a helmet provides only limited protection from exhaust noise. When using wrenches,
adjust wrench so it can be pulled rather then pushed to prevent injury if wrench or sockets slips. Use caution with open end wrench-
es as they can easily round off fastener heads.
2. Maintenance & lubrication schedule chart
Air cleaner
- Clean and reoil daily or after each moto to prevent motor failure and reduced performance.
Transmission oil
- change after every race, or at end of riding day.
Chain
- check tension and lubricate before every ride, adjust or replace as needed. Reoil after riding in damp conditions.
Clutch
- disassemble and clean clutch assembly frequently, every 2-3 races at least. Inspect kickstarter gears at this time.
Ignition cover
- remove cover and wipe dry after each ride or after washing bike to remove condensation.
Piston rings
- replace as often as every 3-5 races with expert rider, less often with less aggressive riders.
Piston, pin, rod bearing & circlips
- replace as often as every 8-10 races with expert rider, less often with less aggressive riders.
Coolant
- change yearly, make sure there is at least a 50/50 mixture of antifreeze if freezing temperatures are possible.
Steering bearings
- Check daily for looseness or play. Adjust and regrease as needed.
Swingarm
- Check often for looseness. Regrease several times a year. Replace bushings if any play is evident.
Sprockets
- check for worn or curved teeth each time chain is adjusted.
Chain roller & wear pads
- check roller for free rotation when checking chain. Make sure roller is not bent or damaged. Check
chain wear strips on swingarm and chain guide frequently. Replace as needed to prevent chain from damaging motorcycle.
Spokes
- Check after each race or after each day of riding for looseness or damage.
Wheels & tires
- check wheels after each race for dents, cracks or other damage. Check tires for cuts, damage or wear. Check tire
pressure daily and adjust for riding conditions.
Shock
- Check shaft area daily for signs of oil leakage or damage. Check swingarm and shock bushings for looseness.
Forks
- Check forks daily for leaking oil or damage to tubes. Make sure forks are not twisted check for smooth operation.
Spark plug
- check sparkplug color and condition after each race or end of riding day. Adjust jetting to keep plug from fouling or
overheating.
Silencer
- If bike seems to be getting louder, replace packing and decarbonize inner tube.
Expansion pipe
- check daily for large dents, damage or leakage. Remove carbon from headpipe when pipe is removed. Have large
dents fixed, or any dents within 8” of the cylinder. Replace o-rings on pipe as needed to maintain a good seal.
Footpegs
- check daily for proper operation, pegs should spring back into place. Make sure pegs are not bent or overly dull.
Handlebars
- check bars after any crash for bending. Look for cracks near bar clamps. Replace bars that have been straightened
more than 2 or three times, or if bar is badly bent. A weakened bar can snap suddenly causing injury to rider.
Throttle
- check throttle for proper operation each time before bike is started. Remove and clean inside of grip and bar as needed.
Grips
- check grips daily for wear or looseness. Replace as needed. Use grip glue & safety wire to help hold grips in position.
Calipers & pads
- check pad wear and caliper function daily or after each race. Replace pads and clean calipers as needed.
Brake lever
- check lever daily for damage or wear. Make sure lever is at proper angle for both seated and standing positions. Leave
lever clamp loose enough to allow clamp to rotate during crash rather than breaking lever. Check and adjust freeplay as needed.
Brake pedal
- Check pedal daily for damage and proper freeplay. Adjust rear caliper as needed.
Reeds
- Remove and inspect reed block during every ring change. Check reeds for signs of wear, fraying and cracking. Make sure
reeds sit flat and seal well. Replace at any sign of wear or damage or at least once a year, more often for expert riders.
Nuts & bolts
- Check all nuts and bolts regularly. Make sure to check engine mounting bolts and swingarm bolt frequently.
3. Maintenance preparation
Before servicing, clean motorcycle to allow better inspection and repair, especially before any motor work to prevent dirt from
falling into motor. Closely inspect entire motorcycle for broken or damaged parts on a regular basis.
