426 head pipe bends?

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?


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

What year was the change done?


Big Al

The change was done in 2002.

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 :cry:
