Removing/altering the CE (octopus) on a 400 with 426(?) head
Posted November 12, 2009 - 10:55 AM
I feel silly asking, but is there an easy way to determine what head I have? I tried to search, but all I found was a great deal of threads asking about and explaining the differences between the two motors, not how to distinguish them. I suppose once I figure out what I have, I'll then move on to altering the "CE."
I'll post pictures of carb and head if needed, as they are both off of the bike at the moment.

Look for a number stamped just below the intake port on the head
5JG00 - you have a YZ/WR 426 head
5BE00 - you have a YZ/WR 400 head

umu, according to what you posted, I still have the 400 head.
gcannon, looks like there is indeed the vac line, so again, I'm thinking 400.
parx, the head is either from a 1998 wr400 or a 2002 426. basically the only difference I know if is the hot start line, and the valves being stainless on the older 400 and ti on the 426. Is that the only differences? I'm so confused.
