It is sludge (including premix) puking out exhaust port.

So is that okay? Not okay? Normal? And how do I go about fixing it?

It could be due to fuel/premix ratio/carb jetting or there could be more going on. Does it seem to run fine or does it feel like it’s loading up? Do you lug the engine a lot?

I only just got the bike, he told me to mix the fuel at 10L of petrol to 200ml of oil because that’s what he has done. He also told me he has had it jetted for doing trails. It seems to run fine when riding, but it doesn’t like to idiol only a few seconds before it turns off not sure if it’s normal for 2 strokes or not

Is that after running on a stand or actually riding

The best way to tell if the bike is set is by doing a plug chop test

You tube, it will be a lot easier than me trying to exsplain

I have an 04 and run 32:1 mix. Maxima Castor 927. You are running 50:1. Not sure if your oil recommends that ratio? Standard for the KX125 is 32:1. I am running stock jetting currently, for a broader range, air temp..I do get a little sludge, but not terrible. Check your oil recommendations first.I would rather run a little rich than to lean.

Take the pipe off and clean out. Plenty of youtube videos. Youl most likely need a repacking of your silencer. Go to local track and make riding buddies. Riders will always help out other riders, its like a religion. Good luck.

All of my two strokes have done this, and I have had some dialed bikes and I don't suck that bad. Even if you run them hard, it's difficult to burn all the premix.
