If you need to do adjustments on your own Tomos Racing then it is usually recommended to possess a Workshop Manual to use as a guide just in case you want to know ways to take off a specific component like the Drive Shaft and fit it again the right way.
Tomos Racing Workshop Manuals will give you specified diagnostic guidelines with regards to your vehicle so if something is wrong it can help you figure out what the situation is and how you can repair it. You will be able to decide if you can do this yourself or in case the job is just too big you can still make a reservation for your Racing in to a local mechanic.
