Yellow crap drained from carb bowl what is it???

(1/4) > >>

psyfi_1:
hi just drain carbs jet 3 for cyclinder three just spat out loads of yellow crud any ideas on what it could be??
its also in the airbox

Bretty:
I think there is an engine breather pipe that comes out the back/top of the engine into your airbox...
Yellow, sounds like a mixture of oil and water..

I've no idea how it gets there as I've not experienced it before... It could just be condensation, she might just want a good run if it's been sat all winter. Clean it up and give it a good motorway run.

Disorderlypunk:
any chance of a pic of the crud
the yellow bit has me confused
is it bitty or sludge like ?

psyfi_1:
allass no its been cleaned now and float bowl runs clear petrol

its was definitaley thicker than petrol in air box but it seemed to flow quite easly from carb 3

i will run her till shes warm now and see if she spits more crap

celticdog:
Yep sounds like a bit of emulsified oil. If you're in the habit of wiping down your airbox with an oily rag or giving it a bit of a spray with wd40 it tends to gather there. I've just cleaned some out my airbox this morning! I'm about to give the carbs a good fettle this weekend once I feel confident enough, was it running lumpy? I'll let you know If I find the same in the carbs.
