You let them put Suzuki standard pads back on again -- hummmm -- bad pick. They are noted for being noisy and short lived compared to EBC premium organic pads.
EBC is the prefered "better pad" around here. SBC is another premium brand, but EBC seems to be gentler on your brake rotors compared to SBC pads. Both kinds will get rid of your noise issues.
Helpful comment here, you need to do your own stuff instead of letting the stealership do it to you. Front brake pads are easy to do -- cost savings AND NOISE savings are considerable if you do your research here on the site and do your own work to put them on.
More helpful comments, you need to try to use the SEARCH function looking for EBC vs SBC, or Front brake pads, or front brakes. There are any number of ways to find out the information you are looking to find out after the fact.
Go to SEARCH, drop down to the "week" tab and click on it and change it to a year or more, then come back up and type in your search string and hit search. You can cut down on the BS by limiting the search to Rubber Side Down and Tech Documents/Reference. Do this several different ways and you will discover there are MANY VERY DETAILED discussions on choosing the best brake pads and changing them out.
Then you dial into the one you like the best and hit reply and add your relevant questions to the end of that thread. Most folks tend to reply to those rather than ignoring a comment that the stealership dumped Suzuki standard pads back into your bike and they are rumbling and grumbling again.
Being a responsible thumper owner, you have got to do better before spending your money like that at a stealership. The info is all here, but you gotta look and search and then ask on your relevant threads BEFORE shelling out your scarce disposable income. None of us has any money to waste any more -- none of us. This means a little more research work up front before making a $$ choice.
All of us need to help each other when we can.
Front brakes really can't be "too tight" BTW. They hydraulically retract the same amount of clearance from the squeezed position every time (unless that stealership left them hoses plumb full of air bubbles for you to have to bleed out or they put the thing back together incorrectly with the pin in a bind or the sliders not aligned or lubed or SOMETHING ELSE GROSSLY WRONG about their workmanship).
"Bleeding front brakes" "Adding brake fluid" -- more search strings for the Search function.
You will get the hang of it eventually ..... and don't let an old geezer get you upset or discourage you either.
Hey, I betcha a whole flock of nice people will be along directly to yell at me for being too blunt and to tell you nice encouraging type things and soothe everything over.
I summoned them for you. I wuz being helpful ..... they will be here momentarily.
