racer8 Posted December 19, 2004 Did Yamaha use two different bends on their yz426 head pipes? I have 2001 and the head pipe seams to really loop out big and then back around. Did they change to a shorter tighter looped pipe? Thx Share this post Link to post Share on other sites
blireef Posted December 19, 2004 Yes, on the first ones you couldn't get to the oil filter without removing the pipe, they changed that so you could. Big Jim Share this post Link to post Share on other sites

Rip Wheeler My Rides (11) Posted December 20, 2004 I had a 2001 WR426 and didnt need to remove the pipe to change the filter. But I did buy it used, so maybe somebody already changed the pipe on it 😢 Share this post Link to post Share on other sites
