With the relatively inexpensive cost of new replacement internals for the stock Chinese motors, basically gut the entire motor case, rehone cylinder, recheck clearances and replace everything using best parts/pieces with a good torque wrench and you're back in business, of course there are some "tricks" the average Joe may not be aware of, hence, the benefit of having a reputable/knowledgeable/experienced engine builder do it for you....On a typical refresh what all is done? I’m guessing here
Hone cylinder
Change rings
Change valve springs
Change valve guides
Clean/polish or change valves
Change rod bearings

Totally agree with this, parts are cheap on these things! Replace everything but the block and crank when refreshing especially if it has 12+ races on it at 6800-7000rpm.With the relatively inexpensive cost of new replacement internals for the stock Chinese motors, basically gut the entire motor case, rehone cylinder, recheck clearances and replace everything using best parts/pieces with a good torque wrench and you're back in business, of course there are some "tricks" the average Joe may not be aware of, hence, the benefit of having a reputable/knowledgeable/experienced engine builder do it for you....
