Hi there, this is for my friend by the way, I ride a k9 gsxr 600. My friend installed PC V on his 2007 600 and it worked great. But now he installed quickshifter to the same bike, he's having problems with quickshifter occasionally. Is it because that PC v is only for 2009 model and up, if so can anything be done ? Please do help.

Thanks in adnvance
