Why why why why....why. Why do the Chinese insist on using the cheapest POS screws?
That is to cool Max!
Can I use that on my web site?
I bought some door weatherstrip screws from HD the other day......even WORSE than HT hardware, if you can even get your head around that. Fasteners made out of pot metal - pure junk. I took them back the next trip and laid into them. I'm writing a letter to HD. I'm not expecting Aerospace titanium hardware for my house, but wow....
Why why why why....why. Why do the Chinese insist on using the cheapest POS screws? AND WHY DO THEY INSIST ON OVER TORQUING THEM!! AAAAARRRRRRGGGHHH!!
The screws and bolts used in bicycles and these motor kits are pretty small. It isn't practical to use the "reef it down until it goes soft and back it out on quarter turn" method. These fasteners, except for the head bolts, need to be snugged down, not as tight as you can get them. No gorilla needed here.
Allen head socket screws are good, second choice would be slotted heads. Worst of all is Phillips, these are the easiest to strip out the heads to the point the screwdriver won't take them out. Be careful with Loctite, it can make it difficult to remove the screws later on. One useful thing is to replace the nuts on the mounting bolts with self locking nuts. Not on the exhaust or intake unless you get all metal self locking nuts which won't lose their grip when hot.
in the end you get what you pay for, period. I change out all my screws with hardened metric replacements on every build.. There isn't much room to complain when it comes to buying an engine for $150 bucks. That's why we're all here - to help each other with ideas and work-throughs.
When it comes down to it, we can be as snarky as we want to be about the Chinese, but in the end, we're going to buy their kits because they are cheap, and not to get political, but we're currently like 3 trillion in debt to them because we needed money for the wars and we tend to buy up every cheap crap gimmick schtick that they shill out.
our best option is to reverse engineer these things here and make a more solid engine.
the other option is to learn Chinese and address them directly.
I'm think I'm gonna stick with spending the extra $10 on the upgraded fasteners and buying boutique parts sold through the vendors here.
;P
