I would think any 2 stroke oil with TC-3. I have a 2 stroke dirt bike but it’s not oil injected. I use this oil. So did my Johnson boat motor. Pretty universal as far as I know.
any 2 stroke oil will work… the best you can get is synthetic.. & is priced accordingly..
Gearbox/ Clutch. castrol/ valvoline/ car engine oil…
2 cycle engine oil, which is blue. The best oil, would be what you think is the best brand, I wonder if Lucas makes some?
In the wet clutch, I’m not sure, I think I used straight SAE 30. It should say on the cap.
I personally use Maxima Bio. It’s synthetic biodegradable two stroke oil.
What can I say, I do what I can.
Your local motorcycle shop should be able to look up what kind of oil is required for the transmission.
