I do my own. On my first Busa I brought it in and I had a mark on the filter, and the mark was still ther when I picked it up. The exhaust was scratched and it had 28 miles more on it. It took 17 days to do the service. Would have taken longer but I hounded them. The chain was so tight, that the bike suspension wouldnt travel. and the snap in the front was missing. I am aircraft mechanic. At the time, I had only 22 years as an all systems mechanic with 19 Aircraft certifications. Also a Cheif Inspector for 3 Airlines. You know the deal, (Shoulda, Woulda, Coulda).
I now after knowing the local people, have got the staight scoop. They start them up, adjust the chain, spray some LPS on the moving parts, and call it good.
Thats from the Mechanics own mouth.
Maybe people are more proffesional in other places, but in south Florida, No bodys more proffesional than me on my scooter.
