do you pressure wash your bike? I don't know if its possible, but water may be able to get in the breather or something. ????????

cooper1973 17-12-10 18:18
i have done in the passed but done oil change about 3mth ago but only used a hose on engine since then

cooper1973 17-12-10 18:30
just thinking what you said richardsracingmad i have a stg 2 air filter that goes on the air box. is it a possibility when its been washed or when riden in the rain water has got in this and got into the oil? all the oil is creamy colour

richardsracingmad 17-12-10 18:56
its just that I would look for the easier, more obvious cases of water in the oil....I haven't heard of a head gasket failure...and they are very good gaskets....

well i have now put my air box cover back on just now need to do engine flush and new oil+filter and then we will see what happens. i have checked expansion tank and water is approx 1>2 ml below line so begining to wonder if it was my stg 2 filter causing the problem moisture and washing the bike etc

richardsracingmad 17-12-10 19:05
let us know how you get on....

cooper1973 17-12-10 19:07
will do, just hope its the stg 2 dna filter problem fingers crossed

richardsracingmad 17-12-10 19:11
also...is the back of your Stage 2 filter sealed??

the bit that screws to the bike is sort of a tuff rubber so assuming this would seal once screwed to the filter box

richardsracingmad 17-12-10 19:31
you could smear some rubber lube around it...?

i was also thinking mabe going through the filter mesh is prob a possibility.

waftycrank 17-12-10 21:39
Hi, had the same thing on mine. Bike is out in the rain a lot and short trips. Stage II lets the water in through the mesh even when well oiled. I think the water level builds up in the airbox until it sloshes through the engine breather when the brakes are on. Removed the stage II, put the standard cover back on and the oil has been clear for months.

If the DNA filters are oiled correctly & greased sealed, water should not enter the air box, is the drain blocked on your air box?

Air and older (90's vintage) water cooled ducatis regularly form water emulsification in the oil if not run for long enough to burn off the condensation.
Are you getting it out on long enough journeys or just the odd short spin to the shops and back etc?

i see what your saying but this seems to be alot of water in oil for condensation, have drained oil gonna top up with new oil then run it then change oil and filter

right update........i done oil change leaving the bike standing over the weekend draining with both drain plugs out, new oil filter + oil added tues ran bike untill warm oil looking nice and clean, used bike for work today checked oil when i got home oil is still nice and clean. i now intend to add engine flush in next couple of week replacing oil and filter again for final time then hopefully all should be ok.

looks like it was water collection in air box as i removed drain plug on pipe that runs down by the foot peg and plenty of water came out so looks like water had backed up into airbox enough for it to go down breather tube:happy:

richardsracingmad 23-12-10 20:40
ok ...thanks for letting us know...sounds like you have not such a big problem now!!! Good stuff.

I would not use engine flush as it could damage the clutch plates, just flush the oil a few times until clear.

I fitted a drain pipe instead of the lower inspection tube on my air box so the water would run stright out, or you can cut some slits using a razor blade through the clear lower inspection cover, otherwise the lower air box will need to full up before it can over full through the top drain tube.

Full air box stroy here.

cooper1973 02-01-11 22:13

richardsracingmad 02-01-11 22:26

Kev 03-01-11 00:21
Make sure the stage 2 filter is oiled correctly & don't wash over the filter with the hose & you will be fine.

Yours is the only case that we know of were we suspect the filter may have let water in.
