Managed to get around to removing the carburetor de-ice circuit on my 07 Aus spec KLX250.
There were a couple of tricky points in the removal, so I'll describe them here for future reference.
#1. Purchase a 'Hose Joiner' to replace the metal t-piece in the radiator hose.


#2. Remove the right hand radiator shroud. Remove the radiator cap. Drain the radiator coolant from the drain plug under the water pump.


#3. Remove the T-piece from the right radiator to water pump pipe.


#4. Remove the hose clips from the left side of the circuit. The bolt securing the clip marked with the bold arrow, you can remove, and remove the clip intact. (Replace bolt.)
The bolt marked with the thin arrow, you can only wind out about an inch before the clutch housing stops you from removing it. This is enough for you to loosen the clip
and remove it using a pair of snips. (Replace bolt.)


#5. Remove the circuit hoses from the carburetor base. The T-piece on the base of the carburetor is secured with a small philips screw. (Inaccessible without removing the carburetor.) I'll leave this in place until the next time I remove the carburetor. In the mean time I'll blank the holes with some rubber caps.


#6. Finally, remove the hose and then the hollow bolt from the rear of the cylinder head. Replace the bolt with a solid bolt (M8 X 10,) and torque up, not forgetting to use the brass washer.



#7. Fit the 'Hose Joiner' where you removed the metal t-piece in the radiator hose. Tighten the hose clamps. Refit the water pump drain plug and washer, torque up. Refill the radiator. Refit the radiator cap.


#8 Run the bike up to temp, then check the hoses etc' for any leaks. Let the bike cool fully, then top up the radiator. Refit the left radiator shroud. [b]Job done.[sm=icon_guiness.gif][sm=icon_guiness.gif]

All the parts I removed.

good write up..... unless you live in the desert, why remove it? Power gains? US bikes dont have it.....

 

I live in the desert. LOL. Well it feels like it sometimes.
Put it this way. I'm surrounded by the desert. Fact.
Lucky if it touches 6 derees C on the coldest winters night.
Iced carb, I don't think so.
Real PITA when you've got to remove the carby anyway.[:@]

 

ok...... so besides when ur removing the carb, theres no gains?

 

Nup.
But who wants to drain the radiator every time the want to 'tweek' their carby?
And besides, every ounce counts, right?

 

The Aus spec CVK has a anti-ice circuit so would it be fair to say that it is different then the U.S spec CVK?

 

very good point.....

 

I'm pretty sure there are a few differences, but it's essentially the same.

 

why wouldnt they bring that to the us? it doesnt get cold here? wtf.....

 

Yup.[sm=WTFsgign.gif]
Stop bitchin.
You get the 'smog crap.' We don't get any of that cool stuff.
