Bikes are ridden the same way on the same terrain yet they behave differently as far as spooge. Go figure.
That puzzles me to be honest. I never had a problem with spooge on any smoker I had. Then I started with the first Gasser (GP 300/18) and the problem appeared. Bought a 2019 EC 300 and it had the same problem. Bought another 2019 EC 300 same problem. Talked to a mate who owns a 2018 GP and a 2019 EC, both 300's and both have the problem. Even with 100:1 they both spooge. He races I am slow, we both have the same amount of spooge.

I tried from 40:1 to 100:1 and nothing changed. My jetting is spot on, the engine is new and runs really well. It is generally believed that oils with higher flash point produce much more spooge than oils with lower flash point. I admit I think that is correct.
However, I run Motul 710 which has a very low flash point and still have tons of spooge Same with three different oils....
