What fuel/oil ratio should I run

[Chainlube]

I just looked on https://www.bicycle-engines.com/ the mag side seal is 2 bucks the clutch side seal is N/A sold out. But they're $1.10, plus a carb, whatever the cost of that would be. Plus the down time.

I have the 66 cc chinadoll motor on my bike for my break in I ran 16:1 after 3 tanks of that I run 25:1 I am wondering what I should run and if there’s going to be a performance difference with a different ratio

40:1 = 3.2oz. of 2-stroke oil to 1 gal. of gas.. I use Lucas 2-stroke oil semi synthetic

None of us in the forum that have been seasoned builders for more than a few years ever recommend 40:1 on a regular, run of the mill China Girl motor...They need their oil for proper lubrication and for cooling purposes.

On the forum, we recommend no less oil that 32:1 on regular CG motor 2 stroke motors, doesn't matter if we are discussing 2 cycle conventional, semi-synthetic, or full synthetic oils like what I use.

I run a Phantom 85 and after breakin, the factory recommends no less oil than 25:1 unless your in high heat conditions like I am here in the high deserts of New Mexico and therefore run 20:1 per manufacturer.

Oil IS important to the longevity and well being of your motor, why be cheap and chintz out on proper oiling???

I use 32:1 and Lucas semi synthetic 4oz oil to 1 gallon gas .. I've seen people run 40:1 but I don't see any difference except maybe some extra wear on motor

I agree with your recommendations and that's a debatable subject ..I just got by what is popular with many seasoned mechanics I've seen on many videos.

And we have seen many, many, bikes that have turned to rubbish on our members because they religiously followed those youtubers looking for their 15 minutes of fame...Some of those youtuber were members here until they started giving bad advice here as well as on youtube and resulting in problems for our members...of course we got rid of the youtubers with their bad harmful advice.

I trust things I see on youtube about as far as I can throw my computer.

One of the many things I've learned here is oil is cheap, motors aren't.
