For yamaha yzf r3 2015 recalls for radiator hose and lever shifter..do i need to bring in any documents/paper work? Or do i jus scheduled an appointment and drop the bike to you guys?

I suggest calling first...ask to speak with service, give them the VIN, and they'll be able to pull up all documented information on the bike. If there's a recall that applies to your bike, not only will they know whether, or not, your bike has had the recall repairs performed, but they'll know everything related related to said recall. My current bike is the third bike I've had that I've been taking to them, and, while I don't always "agree" work them, I do trust them.

Ok

Probably best to call first
