Thank you so much. I am heading to Arizona the long way round then Reno and home to Victoria BC in 3 weeks. Its a 5000 mile run and this post makes my day. I own an 03 Senna ST4s and love the machine. I know it and ride it hard and she takes care of me out there. A shop is milling the spacer and I'll get it Monday, install and ride. Thanks again man.
