This is all good info. I just received my Tri Z this week after being shipped to me. I started making a list of little odds and ends figuring there may be a yamaha parts center comparable to service honda (I can buy alot for my 250R). I got no where every single part I asked for was discontinued. My bike is black and luckly it came with an extra set of Rear OEM fenders in the Yamaha packaging. I was lucky enough to score a yellow headlight cover new in the yamaha packaging on ebay I'll save because I know i'll buy a yellow next and maybe try the 490 conversion as listed above. My collection is growing fast.
