Have no clue what type of three ring circus the service shop is trying to pull off.  Had my 2006 GSXR 1000 In for a simple Valve adjustment was quoted over the phone $330 get there first thing they have me do is buy 90 bucks in parts.   Told me I had to bring my bike in cold so they could do the adjustment.  So i loaded it up in my truck the night before drove it there and dropped it off. Day later I get a call bike is done but they tried starting it and it wouldn't  idle/run and was pouring out black smoke,  not exactly what you want to hear after you drop off your perfectly running bike.   They asked if they could look into the problem more I said yes so they disconnected my power commander and found out that was the cause of the problem.  $325 Being hard to believe seeing how its less than a year old and was working just fine the day before.   When I went into the shop to pick up the bike they said they would hook back up the power commander and show me the problem. They started it up for me and long behold it was running just fine just like before.   So I have no clue what were they trying to do if they were trying to scam me into buying a new power commander and also charging me for them to look or a problem that never was their.  I have a feeling they hooked something up wrong the first time and correctly the second but do you think they would knock off some money off my $550 dollar bill nope this shop was very unprofessional and I would advise you to stay away from this shop.  Lesson learned.   Also when I brought my bike back home I noticed an air box screw stripped as well as the case cover bolt.    I HIGHLY  RECOMMEND going some where else for service.
