IMPORTANT: On your older GasGas, it would be a good time to check your pedal and pedal clamp to be sure everything is tight. Parts are getting scarce for these now 25-year-old bikes and things in the kick-start area will wear-out and break from simple neglect. 

This video applies to model year 1996 and older GasGas Trial models. 
(1996 JTR370 and all 1997 and newer GasGas models have the newer 18mm tapered shaft that is not a "pinch-type" pedal to shaft attachment.)
