***cross posted in ATV forum for max information gathering*** I searched the forum for answers. Could not find a disscussion on the topic. Here is the bottom line... I wanted a 20mm small end wrist pin for my 2008 YAMAHA WR450F. To do that you need to run a YAMAHA YFZ450 Connecting rod. I cannot find the length of the 2 connecting rods to compair. I was told earlier model 04-05 YFZ had a LONG connecting rod(102.50mm) and 06-up had SHORT connecting rod(101.50mm)-is that correct? I bought this Falicon connecting rod- http://www.ebay.com/...984.m1497.l2649 Did I make the wrong choice in connecting rods? The description says 06-up. Falicon has 06-up and 07-up with 2 different part numbers. I was confident this YFZ Falicon connecting rod can be directly pressed onto my WR450 crank was I mistakened?
