scavenge screen cleaning 09' better do yours

Recommended Posts

Just a heads up if you own a kx450 please clean your scavenge screen

if I could post a pic you would be amazed at the amount of "silicone snake" that I had pluging the screen

 

I have had a new to me 09' ...45 hours (at least) total and 6 since i have owned it

and I was getting blow by from the breather hose (oil driping out)

and I knew it was not rings ie.

no smoke ,starts easy hot or cold and runs great so had to be scavenge screen ...well it was a mess and do not be afraid of doing it yourself

 

took me about an hour...had all the tools and so just check yours to be sure what you got in there on your bike

 

thanks to TT for all the good info that helped me :rolleyes:

Where is the 'scavenge screen' located? Good friend of mine has the same bike. I don't want to have to watch him push his bike through woods..well..maybe

1 left side .. ignition cover

2 pull flywheel

3 oil pump cover (4bolts)

 

 

if u do a search there is great info on the topic

 

 

09' and up need a 28mm flywheel puller needed

to get access to 1 of the 4 bolts that hold the cover in place to get to the little screen

mine was seriously almost half covered with the silicone (from the factory )

87 inch pounds on the pump bolts and ignition cover bolts

 

57 foot pounds on the flywheel nut

 

 

dont need to drain the oil ...lean the bike almost all the way over

remove the botom chain guard bolt

left the hoses and cables in place and just moved the cover out of the way

 

watch the 2 dowel pins on the ig cover

 

watch the 2 very small pins on the inside of the pump cover

motion pro fly wheel puller and impact gun

used 460 channel locks on the flywheel with a rag to hold the flywheel while torquing to 57 ft lbs

Pretty sure the metal was from the inside of the oil filter cover because it was chipped up and the metal on the filter wasn't attracted to my magnet.

Maybe that's the lie I tell myself

Is this an issue on 2013's?

My bike has maybe 5 hours on it and every time I'm done riding I see I has oil residue all around the breather hose

I am not a Guru by any means but it might be 3 things that I know of

1. bad rings- bikes brand new so ...

 

2. plugged up scavenge screen ...might want to go a few more hours and then check it

its still pretty darn new

 

3. overfill on the oil volume

Wishing the pervious owner of my bike had been a TT member

That's not too bad at all. Just doing it's job.

 

Although it looks like your previous owner could have been a bit more gentle with the gear shifts.

 

Good idea to clean it a few run hours after the case halves are assembled.

 

But many guys here on TT over the years have reported damaging their motor when cleaning the oil screen. The tricks are to:

1. Do it with the bike upright so no metal dowels fall inside the cases. It only means draining the oil beforehand.

2. When the pump cover is removed, if you are unsure what you're doing then do not turn over the crank or do anything to disrupt the impeller position.
