Gooey breather

[rc mad]

bit of oil in the airbox is pretty normal, really easy to overfill these bikes when you do a service or check the oil. I think standard way to check oil level is go for a ride, come back, swith engine off, leave for 10 minutes then check oil level.

Best way to do it when changing the oil is to drain the oil out overnight and put in the exact ammount of litres in the morning. I think i had to start the engine breifly to get the correct ammount in last time i did a service.

There could also have been a blockage of the oil filter causing the crank case to pressurise and force oil up inti the air box.

How can a blocked oilfilter pressurise the crankcase?

TBH I'm not sure now I think about it again.

Path of least resistance, oil can't flow through the filter so goes up the breather.

An extremely long shot i know, but i'm trying to make val feel better

Followed very quickly by the engine self destructing

After chatting with a very good mechanic freind, he is inclined to agree with the hypothesis that the breather was probably blocked for some time, and had opened up as the bike is now in regular use...hence the gooey deposits

Apparently, big single engines have a tendency to develop condensation in the crank case...something to do with large cylinders not burning fuel as efficiently as say a similar capacity 4 cyl engine with much smaller cyls, (I didn't really get the jist of it, as I had imbibed a few beers and a couple of large whiskeys at this point)...thus deposits of emulsified oil can develop, leading to widespread panic (in my head )

Just thought I'd pass this on as it doesn't seem to be common knowledge...
