Hey, is this place still open? :-o
Hard to believe it but it's been nearly 9 years since I first published the Caddmann Kit mod.
I never intended this to be a permanent fixture on my bike. It was a stop gap measure until I could afford the expensive commercial kit.
It just worked so well for me I never felt motivated to change it out.
It got me into a lot of trouble though, on another forum where I was a very active member. This is about sour grapes...a total rant....so please bear with me.

Fortunately I can laugh about it now, but at the time I was ticked to no end.
See one of the staff who called himself a mechanic and an engineer couldn't think his way out of a paper bag when it came to any part of this business requiring logical reasoning. He also could not accept being spotted as wrong, but it happened over and over. The most glaring event occurred when he was asked to describe a radial tire construction, and clearly described a bias ply tire. Then he defended his idiocy with lies and misdirection.
He was a mod, and he maliciously screwed around with my writings on the forum, changing my words, then flatly told everyone I hadn't created anything new (essentially true, it's a well-known concept)
and that there was really no such thing as the Caddmann Kit at all!
I quickly Googled up 21 sites describing the Caddmann Kit, referring to it on another site, or like this thread, republishing the information with new photos and improved descriptions.
Over a dozen people (that I knew of) on that site were already running it too.
I posted that info & it didn't sit well. I never received an apology. He had a lot of influence on the staff, and so in fact I was roundly harassed, and then banned!
I did this mod for sound reasons, I did it carefully, with a thought to making it as inexpensive as possible, and completely reversible in case of legal issues or performance problems; and I published the results for notariety of course

but also with a thought to help other owners with their bikes.
I've done several of these for other Kawi owners, and I've corresponded with dozens of others about it. I never made a single dime of profit from it all either, nor did I bother attempting to.
So whadda they say?..."No good deed goes unpunished." LOL
So here I am

9 years on the Nomad and I'm still running the mod I developed because I didn't want to pay $300 for an air filter.
Also I just Googled "Caddmann Kit and Caddman Kit", Cadman Kit, and Cadmann Kit, and came up with 2000+ hits.
Not all of them were about this mod, but the great majority seemed to be.
I guess it really does exist, Toto!
