Do you prefer to pay through the nose at a main dealer?
Do you support your local small workshop?
Do you get a warm feeling from getting black fingernails? (and a healthier bank balance)
I like to have a go myself and, when nothing fits back or works, bag up all the bits & then go to my local mechanic
. . . which by co-incidence is where my f**kin bike is at the moment, having a new alternator fitted 
I normally have a go myself, and save a bundle 12,000 mile service on the Ducati is around about £550.00, went and bougth a haynes manual and parts for £198.00 took a day but managed to do the service including timing belts.
Only use the garage for electronic calibration
I like to do as much as I can myself. There is so much info available on the internet from owners groups and service manuals so I try and read up on what I am going to do then have a go. If all else fails I have a mate who is quite handy with his tools so he will always come and give me a hand if I get stuck.
Would love to do it myself as the thought of paying out hard earned cash is scary…
Sadly no garage… Betted dig deep into those pockets
until now used small workshops but now as I am not dependant on the bike for work I will be trying to do a lot more myself.
Going to a dealer or a small workshop … they both do they same job right, so what are you paying the extra for exactly ?
I’m handy with the old tool box … not saying I’m any good at it … but I can get by … and Yes, I like removing the dirt from me finger nails at the end of the day feeling like I’ve acheived something 
One tip though … don’t try removing your exhaust with a junior hacksaw 
Where’s the option - Oil & Filter yourself & hope the rest is just overkill
I’d like to do it myself, I have all the tools, however I don’t ever have enough time, I have no garage so have to work in the open (not pleasant in the middle of winter) and the last time I changed the oil I cross threaded the sump plug which cost me a fortune to make better. So I now use a very small workshop local to me in Gillingham,Kent which doesn’t cost the earth. I only ever use main dealers when the bike is in warranty.
A decent main dealer will be experienced with the marque, and more readily able to source parts and identify problems specific to a model. They will also have the required specialist tools to allow a bike to be serviced properly rather than important items missed altogether because it falls in the too difficult box. Or worse still, bodged.
Which isn’t meant as an argument against smaller workshops, but does explain some of the differences.
Myself, I often do the work myself. I’m quite happy to do all the routine work on my current bikes as they are very easy and pleasing to work on. My last bike was pampered a bit (it was the only pampering it ever got) and treated to a trusted main dealer for every service over it’s life. Which was purely because for once I could afford it and because for most of the time I owned it it was my only bike. This made a dealer who was happy to lend out loaners quite appealing, as did living two stops on a suburban train line from the dealer.
The last two. It was a combo of them today. Worked alongside mechanic to sort the bike out. Snapped exhaust stud. I don’t have the tools, local bike shop does, and they don’t mind if you do the donkey work and they do the specialist work. Saves you money and them time!
always done me own
Always did my own. Learnt some lessons the hard way but think I am quite good at it by now. Most of it is easy and you should know how your bike works so you can spot potential problems like brakes, chain etc. I’ve even bought another bike as a fixer upper.
The current bike being just a year old and still under warranty I took around the corner (5 minutes from home) to the local Yamaha dealer where I purchased said bike. They quoted £180 for a 6k service. Even though I gave them a K&N air filter to swap with the old one, plugs didn’t need changing, just oil, filter, a few sundries and labour came to £200 
I could have done most of it myself, other then balancing throttle bodies, and saved about £150 but I wouldn’t have had that all important stamp in my book just in case something went bang!
