Hi.. A great way is to remove cover " since you need to grease the clutch arm actuator upper and lower, and this requires removing the cover, failure to grease the upper and lower portion of clutch control actuator upper will cause premature wear and cause loss of clutch operation , factory never puts any grease on those required grease points" and also remove the spark plug from the motor so there is no compression. This will allow you to turn the engine sprocket with a socket and thread the chain through easily. Enjoy the ride..
