can't belive I will be left in the dark ( been there a lot in my life ). this is a great forum and has provided a lot of help in the past.
I general break in with castrol oil fuel, but some have said 15% Nito seny would be alright for break in. I have some 15 %nitro and could add some caster oil to it, but that would drop the nitro by volum?
If I may add. I would not recommend the use of castor with a YS. Go with Petec's recommendation of cool power and you will be happy.
