thanks rhys |

I think what you are referring to is an emulsion of oil/condensation that looks like mayonaise. Perfectly normal and found in cars too. Usual cause is lots of short journeys where the engine never really gets up to full temperature for very long and the bike is stored in damp conditions. Give it a full days ride out somewhere.
Of course it could mean that your head gasket has failed and the coolant is mixing with the oil but then you would see the mayonaise on the sight glass too and your coolant level would be dropping. Most unlikely. |

I had this after I dropped the bike on some Ice at the beginning of the year , washed it out under the tap and shook the water out of the sponge , it never came back .

rocket thanks for reply this had crossed my mind but like you say there would be mayo in the sight glass but the oil was fine when i drained it off. the bike gets used everyday to and from work 30-40 mins each way 40 mile round trip so gets a good warm up Last edited by 2hys; 03-05-09 at 12:21 PM. |

The rear pipe under the "Sponge" is from the coolant , I had the airbox removed the other day to balance my throttle bodies and noticed the coolant spitting up from the open pipe . When I saw the emulsion in the Sponge I realised it was from when I dumped the bike on the deck , it was down for about 10 seconds and was enough for the coolant to leak into the sponge ..... it just stops the throttle bodies inhaling the coolant in this eventuality .

So the expansion tank overflow goes straight into the airbox? This is very odd.
Some water/emulsion in the catch tank is no big deal though.

No mate , I should imagine there is a smaller overflow style pipe that is a little bit below that , then that would head for the deck under the bike somewhere . I do think it`s a bit strange to have those breather pipes in there , probably something to do with keeping the air supply to it a bit on the clean side if anything ...... somebody will supply an answer at some point as I am quite hungover and .........................................meh!!!!!! I`m going back to bed .
