Yes that’s the one. l would love to see the maths behind it,unfortunately dtpedia.de doesn’t mention it when referring to the vergaser or carburettor as we know it.

No I didn’t mean the yeis bottle I was referring to the other one on the air box side of the carb.

It’s also worth remembering that carburettors like still air, that’s why the air box is so big, so if you have that strange bottle on the side of the pipe that connects the air box to the carb, it needs blocking as it’s designed to disrupt air flow as a form of restriction.

You can get ebc brand pilot jets on eBay. They work fine.
The power jet system takes fuel directly from the float bowl via the grey pipe on the side of the carb, often gets blocked and stops working. It’s a bit of a rough and ready system for extra power when the throttle is fully open.

Go to motocarb select parts then tm and it’s no.2
