I had the same issue with mine, it blew oil up the breather, but only when ridden very hard. However it collected in the catch bottle, which sometimes overflowed and didn’t leave much residue in the air box. Personally I think it is due to a breathing problem, where the bike isn’t getting enough air when at full throttle, causing a vacuum in the air box and excessive pressure in the crankcase. Yours though looks more like mayonnaise rather than just oil, as though it contains a lot of water, which is odd.
Thanks, I had heard similar from a mate of mine. He thinks he might have a solution, I’ll check and make another video on the topic. It might just be the light, the oil looked fine when I cleaned it out but I will certainly keep an eye on it. Sometimes water can get in the air box if it rains hard or when I wash the bike, if it mixes with the oil that can cause the discolouration. Thanks for the comments, much appreciated.
Hi I’ll see if i can do a Domi gearbox video shortly, not so much fallout - it’s all good now. Not sure what you mean about the suspension setup though?

That's not so good!
Blocked crankcase breather?
Any of the forums offer any helpful ideas?
Hmm could be. I'll keep an eye on it. A mate of mine has some ideas about how to fix it.
It’s British, it’s got character 😝 it was always a problem on old Brit bikes, they don’t breath to well.
Haha indeed! Well said! 😃
