Oil preference is like most other things. You need to do what works for you and let others do the same.
hi me too.
i broke my 66cc engine from the start 100:1, and i sold the bike with a 1000 miles on it and it ran fine. i never did seam to have a break in, ran like a striped assed ape right from the start. i pulled the head befor i sold it look like new.
i just got a HF 79cc Predie i am going to pull the side cover and clean it out an fill it with opti 4 to break it in..
I think using opti 2 is like having sex for the first time, worried and nervous till it over, then love it !!!!!!!!!!!!
