If you have to accomplish maintenance to your CPI SX Supercross then it is always recommended to have a Workshop Manual for personal reference if perhaps you need to know ways to remove a specific component like the Door and fit it again properly.
CPI SX Supercross Workshop Manuals can provide unique diagnostic details for the car or truck therefore if something is broken it will help you work out what the problem is and the best way to correct it. You will be able to decide if this can be achieved on your own or in the event the job is too big you could make a booking for your SX Supercross in to a suitable garage.
