Clutch System
6. Start the engine, pull the clutch lever/parking brake lever in, and shift
into gear. Make sure the engine does not stall and the ATV does not
creep. Gradually release the clutch lever/parking brake lever and open
the throttle. Your ATV should move smoothly and accelerate
gradually.
Check the clutch lever/parking brake lever and clutch cable for loose
connections or other damage. If the clutch cable is worn or kinked, have
it replaced by your Honda dealer.
Other Inspections & Lubrication
Check that the clutch lever/parking brake lever assembly is positioned
properly and the securing bolts are tight.
Check the clutch cable for kinks or signs of wear. If necessary, have
it replaced.
Lubricate the clutch cable with a commercially available cable
lubricant to prevent premature wear and corrosion.
