Welcome to the forum!

No way to check really. Ideally I always change the oil after every day out. Drain out using the drain bolt, reinstate drain bolt and copper washer. Fill with 60ml of oil by removing the breather cap, then reinstate the cap.

We use Silkolene Gear Oil SRG 75, it's about £20 for 1 litre. Gives you about 16 gear oil changes.

Maybe worth identifying that this is gear oil.

Yes it is gear oil

In all honesty sounds pretty spot on. You'll know when you go to lean as the engine will pop down the straight, then go up 1 jet.

Always good to talk to your engine builder for tips as each engine/card etc can be slightly different. Need to find what works for you.
