Fuel/oil ration help

[Noddy made me]

Can somone help with the correct fuel/oil mix for a suzuki ts50 (c) 1978- ? not the newer ts50 (x). Advise so far has ranged from 25:1 to 50:1 to dont put too much, or too little in Man at suzuki dealer asked what a ts50 was
Read somewhere that the mixtures arent relevant now cos the oil quality is far better now than is was then, kinda makes sense..
thanks chaps
regards Tony

Edit, yes i have spotted that ive typed ration and not ratio....... let the rationing p[$$ take begin...

Phoned two more suzuki dealers today and got told 20:1 and 40:1

It's actually six of one and half a dozen of the other.

Seriously though, I'd try 50:1 and if that is a bit smokey or hard to start, go to 100:1

Most strokers, outboards, etc. seem to be ok on weaker mixtures than of old, due to improvements in 2T oils.

After careful consideration and having found a measuring jug in the kitchen that had 125ml(gonna hide it in the garage and deny all knowledge of it) i opted for 40:1. Then having put half the 5L can in the petrol tank i realised that i had connected the new fuel pipe to the tank, but not the carb So after a quick tidy up (and some more fuel) i was ready to try and start it. Seven kicks ( i counted them) and she was up and running Had to reroute the throttle cable cos it went a bit mad when i turned the wheel to the right
Went for a spin round the garden and returned to back to where i was working to pick up tools etc. Left the bike running and promply filled the downstairs of the house with the smell of 2t
