Yaxy Posted April 15, 2020 Report Share Posted April 15, 2020 This is a great conversation and like the rest of you I am learning a lot. Over my 30 years as a Banshee owner I would like to share the following points: - Your engine is a pump. It needs a combination of fuel and air to run. An imbalance of any of these 2 components can lead to performance and longevity issues. - Since you are on a 2 stroke, let’s define fuel as a combination of Oil and Gas. Air is the 3rd component. - Your carbs have a pilot and a main jet where a combination of gas and oil flow through them. - When I was a youngster, I used to think more oil made my motor run richer. This is incorrect. Gas keeps your motor cool, oil is there to lube your parts. (Think of a 4 stroke motor, you don’t put oil in your gas tank). The more oil in your gas/oil mixture the leaner your motor is running. - With the above said, after an engine rebuild, I will always run a little extra oil in the gas for extra lubrication. I will do this for the first 3 tanks of fuel and then back to my normal gas/oil mixture. What I have learned. I used to mix 20:1, then 32:1, then 40: 1 and now 50:1. I feel 50:1 is a comfortable balance of a gas to oil mixture for the modded Banshees I own. We want to keep our motors lubricated thus we want to use the right amount of oil, not too much, not too little. The oil you buy should have a recommended gas/oil listed See what they recommend (Call the manufacturer if needed) and use this as a starting point. Whatever you decide on for a mixture, always remember to verify your jetting. 1 Quote Link to comment Share on other sites More sharing options...

ClaudeMachining Posted April 16, 2020 Report Share Posted April 16, 2020 Oil is also there to act like a seal between the rings and the cyl.That's why 20:1 will give a little bit more power than 50:1.Envoyé de mon SM-G965W en utilisant Tapatalk Quote Link to comment Share on other sites More sharing options...

Deets Posted April 16, 2020 Report Share Posted April 16, 2020 Are there any advantages of running 50:1 over 32:1? I can’t think of any, besides that it’s cheaper. Quote Link to comment Share on other sites More sharing options...

Yaxy Posted April 16, 2020 Report Share Posted April 16, 2020 (edited) Cheaper and less smoke as mentioned above are good advantages. I used Yamalube 2R at 40:1 for probably 15 years and found it excellent at lubricating but it didn't burn as clean as I would of liked. I now use Legend brand oil at 50:1. It seems to run cleaner, smoother and I am happy with it. Edited April 16, 2020 by Yaxy Quote Link to comment Share on other sites More sharing options...

Envoyé de mon SM-G965W en utilisant Tapatalk Smoke is from the tune, your rich if it’s smoking. I have no smoke at all at 32:1 when it’s warmed up.

ClaudeMachining Posted April 17, 2020 Report Share Posted April 17, 2020 Wait, you're telling me that more oil doesnt create more smoke?? Are you trolling me??? Hint: Four strokes Envoyé de mon SM-G965W en utilisant Tapatalk Quote Link to comment Share on other sites More sharing options...
Deets Posted April 17, 2020 Report Share Posted April 17, 2020 So oil ratio is the only thing that has any affect on how much smoke you have? I’m sure it may be a little different, I’m just sayin if your jetting is spot on then the difference would most likely not be noticeable. And if a little extra 2smoke bothers ya, then maybe you should stick to 4 strokes. Lol Quote Link to comment Share on other sites More sharing options...

LolI'm sorry but there is a lot of smoke difference between 25:1 et 50:1.You know nothing about smoke bro ;-)Envoyé de mon SM-G965W en utilisant Tapatalk Quote Link to comment Share on other sites More sharing options...
