oil leaking from air box
hi
I have a 2005 450cc FSE that I just bought. After the first ride I noticed some drops of engine oil leaking from the bottom of the air box housing (the black box in front of where the air filter is) First I thought it might be because of too much oil so I replaced the oil according to spec. (taking care to empty also the oil in the frame) But is still leaking. Any ideas? I was thinking engine breathing problems but I dont have a clue how to check that. Thanks in advance. |

That is a common problem with the 450's. I believe that the breather filter has to be in place and in place correctly to function. I wish I knew more about 4t bikes...

The 2005 is a notorious driveler. The breather hose needs to be split and retrofitted with multiple foam inserts. There was a factory kit for this including all the necessary items.

Just stuff the hose with very open foam.

The bike then obviously will draw unfiltered air so that can not be good. This will also show a leak for any drop of oil that is drawn through the breathere. I will therefore start by pluging that hole and see if that fixes things. My guess it that the former owner made that hole because oil was flowing out through the airl filter and he thought this was a fix for that!!!!! |
