Anyone got a description of the interim service in English or at least a list of what should be looked at?
Should this be stamped in the book?

I have a mate with a '97 916 that was used very little for 3 yers and not at all for the last year of the 3. He then got it serviced by Baines and the belts were in a very poor state just from being stood that long. The worst thing you could do if you think it may have not had belts replaced "recently" (i.e. within last 12 to 24 months I guess), is start the engine and ride it to a service!

My 748s had done 5700 miles when I got it.
Full service history but nothing for last two years (1700 miles).

Had belts done at 6000 miles and good job too as they were fraid with little cuts in them.

Good job I didn't wait for the scheduled change at 12000 miles hey !

Indeed. As they say, it's 6k miles OR 2 years for the belts and time is a killer too.

Basically,if the bike is very low mileage,there is no need to check the valve shims.Everything else is done,i.e oil/filter change/coolant,fluid checks/brakes,suspension inspected/bolts re-torqued,etc.Cam belts are replaced if required.(If its two years or 12k miles since the last change)
So really,its everything,apart from checking the valve shim clearances and changing the belts.
I think the service shedule is printed in the handbook.
The missus Monster is just 3 years old but low mileage.It has just had an interim service plus belts.
And yes the book would get stamped.:)
