Recently had to replace my steering stem on my 06 YFZ 450 due to a crash. I located a new, stock aftermarket stem. The listing said for 2007 through 2009 and I thought they would interchange. I installed it with a new pitman arm but it now has too much play, about a 1/4 inch to each side. So much so, that even though the bars are straight, the front tires track left or right. I'm going to locate a used OE, but I was wondering if it has to be off another 06. I have check eBay and what I'm finding is 04-05 and 07-09. Is the 06 steering stem specific to the 06, or is there another underlying issue on why so much play with the aftermarket stem that was listed for 07-09?
