GSXR-750 EXCVA problems
First some history:
My first sportbike (that I owned, not a friends) was a 2006 Gsxr 600, i bought that bike new in NY and from the very beginning had problems with the FI light blinking. After several FREE dealer services to try to fix it, i was told it was related to the EXCVA (exhaust control valve). The NY dealer also told me that this was affecting a lot (if not all) new 2006 600/750 bikes at the time. After a while the problem seemed to occur less and i just accepted it. I moved to south florida in early 2007 and once again the problem returned. So I took the bike to a certain very-south florida Suzuki dealer (the nearest to me). They told me it was a cable adjustment issue. After adjusting the cables the problem was still there. A few months later I traded that bike for a new 2007 Gsxr 750 from that same dealer. 9 months after that the very same problem began to affect the new 750. I took it back to the same un-named dealer and they told me it was not covered under warranty and it would cost $300 to adjust the cables. I called suzuki and they said go to the dealer, who once again told me it was not a warranty repair because Suzuki wouldn't reimburse them for it.
So I bought the dealer manual on ebay for $5 and followed the semi-complicated procedure to adjust the cables. The problem went away. A year later it once again returned, so i adjusted the cables myself and it seemed to work ok again. Now a few weeks ago the problem is returning, although now the EXCVA unit itself is making a clicking, so im thinking its time to replace that.
My question is:
Has anyone else had this problem with the 06/07 and possibly newer models of 600/750 or do i just have really bad luck with this? Also is there a way other than using an aftermarket header to bypass this system? Any other thoughts are also welcome.
