Fuel/oil mixture ratio

Postby ochosolamente » Tue Mar 31, 2015 4:40 am

i just took possession of this little gem. Problem is i don't know what the fuel/oil mixture ratio should be. Anyone have an answer or a educated guess? no, it's not an Ariel. It's a 1959 Peugeot TS 125 2 stroke. Any help would be greatly appreciated. I wanna ride it!

With 1:20 or 1:25 your always good, if your using very modern outboard engine oil you could raise to 1:30.

I thinking that 20:1 is safe. Rather have a bit too much.

Try this link to a post on another site: http://motoancienne.superforum.fr/t9009-besoin-de-documentation-peugeot-p57

If you need to translate use Google chrome, right click on the text / words and select translate

There is a link in one of the posts to another site where you can apparently download documents for Peugeot motorcycles.

Here's another useful site for working out oil volumes. Don't forget that increasing oil volume makes the fuel/air ratio weaker. http://www.csgnetwork.com/oilfuelcalc.html

How much oil you usedepends on the quality of the oil. Modern oils are very, very much better than those available when the Leader/Arrow manuals were written.

I use fully-synthetic racing two-stroke oil, at 50:1, but not for racing, only road use. No smoke, no problem.
