Pics - '05 California WR450 AIS (smog) setup
Posted November 04, 2004 - 07:23 AM
Some folks from my other thread wanted to see pics of the AIS (air injection system) for the '05 California WR450. So here ya go....
The first 3 pics are from the right side of the bike where mostly everything is located. The last pic is from the left side just in front of the air box showing the fitting that feeds the AIS thingy.
Click here for the break down page from the manual. *WARNING* this is a rather large file. So 56k users beware!
Its looks like they're using crankcase pressure to siphon clean air from the airbox and pump it into exhaust port.

I notice in the manual they call the smog pump (box) an "Air cut-off valve". My guess it's something simaliar to the ACV on the carb. Does the '05 still have an ACV on the carb or is this the same thing on a bigger scale?...or is it just in addition too?
Greeaat, now you guys are going to make me look at mine!!
I've been reading on the '03/'04 ACV/TPS mods. Guess I'm going to put on my guinea pig costume and find out.

Another great reason to buy an 04 while you can! That looks terrible!
Yeah but it'll look a helluva lot better after I slap the GREEN STICKER on it!

Just curious how is this AIR system powered---I'm assuming it is electric??
I asume its pulse injection. Just the pulses in the exhaust will draw in the air. I may be wrong, it may use a pump, but doesnt appear to and I assume Yammie didnt want to hang too much off of it.

Arrived back from Blaine at 11pm with my best friends 2005 wr450f Canadian model (sticker on head stay says Canadian purchased from Motorcycle Brokers.) It has the AIS system. I was surprised.
