Hi Mr. Cob,
Welcome, from one old fart to another.
Like you, I have a rotating assortment of 7-10 bikes at any given time. My current mix includes a couple of TW's and a DRZ400SM. Within the past few months I put kickers on both a TW and the DRZ. It was probably your guide that I followed for the DRZ, so I'd like to thank you for your efforts putting that together - much clearer and easier than trying to follow the instructions that came with the kit.
