Dude I wish I could help you identifying which one it was but I can't. Ours had a #10 on it too, and no one ever responded to our questions with answers.
BUT.....
I CAN help you get that bike set up. We have learned a LOT about both bikes in the most recent month. Previously, for a spell, I was total anti R. Now we plan to resurrect our R plan entirely. We have discovered that it actually IS possible to set the R up just like we have our standard setup - which does work rather well.
Your answer to setup is Nichols Manufacturing. They plan to sell the two pieces that we helped them develop for about $750. Remember that number well, because of all the things you buy for your bike, none will be more valuable to you than these. Someone somewhere sells a rear ride height adjuster for Superdukes - it goes for $500 all on it's own. Nichols is selling BOTH pieces (rear ride height adjuster, and the upper triple clamp) for only $750.
Forget wheels, motor work, or anything else - until you get these pieces. You will love yourself, trust me. PM me for Jon's email.
Congrats on your purchase.
