Default RE: ys fz 63 break in
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?
