Hello , first of all i have always used putoline gear light in my 125sx , i ride most weekends and change it every 4 to 6 weeks and it has always been fine . my trye pressure at present is 15psi front and back this is a good starting point but try to find out what suits you and the tracks you ride on.
as to the other part of your Q i run my bike 33 -1 which is around 150mm of 2 stroke oil to 5 litres of fuel , also i use putolione mx5 oil which i beleive to be one of the best. hope some of this helps tom ........dave
