Oil is milky/foamy

I was suffering from the same thing with my 7r but luckily it was becoz the bikes been parked up and started at random (condensation build up)
Drained the old shit out and flushed with some cheap oil from halfords then renewed filter and filled back up with the good stuff
But to answer your question worse case scenario is cylinder head issues
Like kawathrasher said, people often start to panic over this symptom but quite often it's just condensation. Has the bike only been used for short blasts (less than 20 mins) through the winter? If so there's a high chance that's all it is, give it a good length ride and see if it's better or worse. If it's got worse after a lengthy ride then you could have real problems.
cheers lads for your replys
ye bike was parked up all winter and started from time to time, but i changed oil and filter 2 week ago before i took her out and have only noticed this problem de other day, going to change it again then see what she is like then......thanks again for your help and fingers crossed it will be ok..
Just as a thought has the bike used any coolant ? i would check that before goin for a thrash coz you could feck the engine if it is a more serious issue i.e the oil could be waterd down and not doin it's job
Check your levels and then take it for a good long run, 45 - 60 minutes minimum, let it idle until the fan cuts in then ride it home and let it settle then check again.
Most likely as said it'll be condensation which leaves a white foamy gunky skim on top of the oil window and filler.
A good long run and getting the engine hot will evaporate the condensation.
