This is a step-by-step guide for premixing your 2-stroke oil for your mini moto.
Step 1 - First you need to get a certified petrol container* to store the petrol you will use in. You will also need to buy 2-stroke oil to mix with the petrol for your mini moto bike.
Step 2 - You will now need to find out the amount oil: petrol ratio that your bike uses. In my case it is 25:1 so I will use this figure for this guide.
Step 3 - You will need a measuring cylinder to measure the 2-stroke oil with.
Step 4 - You now need to work out the amount of 2-stroke oil you will need to use. If I am going to buy 5 litres of petrol I will need 100ml of 2-stroke oil. You will need to measure this amount out in the measuring cylinder.
Step 5 - Now you have measured this amount out you need to pour it into the petrol container.
Step 6 - Now you need to pour 5 litres exactly of petrol into the container.
step 7 - You will now need to thoroughly shake the container for 2-3 minutes to ensure all the oil and petrol is well mixed.
step 8 - You can now pour the petrol into your mini moto bike.
Make sure that the container you use is clean and has no petrol already in it. This will ensure that the petrol you use is clean and the right mixture, you do not want to be putiing petrol in your mini moto which is months old.

The mix you've described is
The mix you've described is 50:1 not 25:1, you need 200ml of oil to 5 litres of petrol for a 25:1 mix

BSA Bantam pre-mix
Most old British 2 strokes used a 16:1 mix so if your 20:1 appears rich then I guess that the carburation is wrong. You can use 20:1 with modern 2 stroke oils or, if you want to be totally 50's use a single grade (SAE30, half a pint to a gallon. OK, so it smokes but then all British 2 strokes of that era smoked. If you have ever seen a Villiers 2T (250cc twin) at full throttle then you would understand. Remember that these engines used piston controlled ports as opposed to reed valve so fuel/oil separation was a bit less effective and quite often the big-ends were a lot less meaty than today which is why many had crankcase drain plugs as standard. Best of luck.
two stoke mix for BSA Bantam
Did you get any responce to your question? Ive a 1964 D7 which Ive just restored. The 20:1 original mix seems to rich using modern two stroke oil. Any information would be a help.

lol you spelt make wrong!!
at 25:1 solution you will
at 25:1 solution you will need 200ml for 5 litres of fuel - not 100ml as stated....
and add oil to fuel, not fuel to oil....
sssscchmeeeeeee

just adding some lovely science
to ensure a homologous solution is attained you should flip the container aroudn 21 times this is proved by trial and error and will ensure you a perfectly mixed solution !!
