Re: How do You break in your ht motor?
Like Davezilla said, there's so many answers to this question. I mean, it's the proverbial can of worms in a necromancer's subject.
When it comes to chinagirls there far more ways _not_ to break in an engine than there are so-called "proper ways" to break one in.
Each one is like an individual human being in a way, but with a much shorter lifespan. What works for one will not work for another, every one likes to be rubbed a certain way. Many will blow up before you figure that out or do it just as you think you have it figured; the lucky ones will love ya long time.
It's all a lottery. IMHO, the best thing you can do is treat it with respect and don't get greedy with power and/or speed. The chinagirl is based on a design over 70 years old and was not designed for you peel out, do wheelies, and do 40+ on highways. No, it's really not.
Most important: don't "fix" it if it aint broke.
