About time. I have always hated the stock mc on the 1000s. Owned 2 of them (Shamless bump - I have one for sale in the WTT classifieds ) & never liked the engagement point nor did I like the feel at the track.
Did a bit more digging, Looks like we will find out for sure next week..
"All new or Used 2004* thru 2013 GSXR models 1000 2005-2013 750 2004-2013 600 2004-2013 Suzuki Motor Corporation has instituted a safety recall campaign to replace the front brake master cylinder. The brake piston inside the front brake master cylinder of some motorcycles may not have received adequate surface treatment to prevent corrosion. Corrosion of the brake piston generates gas, which may not be adequately purged from the master cylinder due to the side position location of the reservoir return port. To ensure customer safety and satisfaction, dealers will replace the front brake master cylinder and brake fluid. Technical Service Bulletin: Servicing information regarding this safety recall will be available in a Technical Service Bulletin the week of October 28, 2013. Parts Availability: Dealers will be able to order the necessary parts to perform this recall campaign beginning approximately the week of November 4, 2013. Adequate supplies of parts will be available at that time to ensure your ability to service all your affected units. Your dealership may immediately resume retail sales once the recall campaign is completed.
