Max, I used the search function to look for 'insulation panels' and all I got was this thread. 
Yeah, I know. That is why I said sometimes it is the enemy

I know Jim will chastise me for this, but I still say the searching functionality on SMF is pretty weak. But it is doable if you get creative with terms and which forums you search. In this example, the found thread was not in this Forum... using the search box while pointed at the" Accessories and modifications" forum will ONLY search this forum and none of the others. While that might be what the users wants, it isn't clear that is what it is doing. It doesn't even SAY the results are from just the forum you are in when it returns the search results. I am also convinced it doesn't show all matches.
Of course, the other issue is that I knew nobody would call them "heat shields". So searching for those terms would be futile (although I tried it first). Instead, I used "zteve heat" and started at the main "The C-14, aka Kawasaki Concours-14, the new one" page's search box and the rest is history.
I really think we need a search "Howto" that is sticky. And I will put my money where my mouth is by writing it, if so requested.
