So, what is really in a service if you take your bike to dealer?
My bike is due for service round 12 000km, and according to the dealers they will charge me ab out 2 hours labour, then add the spares and sundries and all the other crap they can think about, and you walk out with half empty wallet.

So i check out the service manual and mainly it tells me toe check this and check that, tighten this and clean that. All things that seems very simple.
The only thing that i can see to adjust is the idle speed and chain tension. This is things i do on regular basis anyway.

So my q is ....why do they claim to work so "hard" on the bike. One guy even told me that they have full diagnostic test in place for the bikes... .

So from when is it really serious, really difficult , and do i need specialised equipment to do this real serious services.

cheers
