Well yeah, in my opinion one needs to enjoy fixing a china bike in order to fix it. If fixing the bike is just a pain, then it does not make much sense to fix it.

But if you want to learn to fix and mod a bike, then China bike is not that bad core bike for that because you can make a total autopsy for it, break everything into pieces, if you want, not a big loss. I hate to say this because I like motorbikes, but at times it can be better to just move on.
