Cam chain tensioners shouldn't need adjusting unless they have been converted to a manual style. Perhaps you are thinking about a valve clearance adjustment and those should be done according to the manufacturer's interval.ShanMan14 said:I've never had the cam chain tensioners adjusted on my SV650S. Am I begging for a problem? It's so darned expensive to have it done and I don't even trust the local shop all that much. What's the going rate $100/hr?
Althoug rare, there is the possibility of doing damage by not having the valve clearances checked regularly.
