Stainless is not hardened it is softer than regular steel which makes it tougher and less brittle. but don't use it in high torque apps (kit sprocket) as it likes to gall and once it does you won't get it apart w/o breaking it. Use Grade 8 on the sprocket, but SS works well on all the motor threads.

Honestly, I don't use a torque wrench. I tighten slowly until I get to that "certain resistance".

I do strip a lot of the original stuff.
Naw, nope Joe. But nothing strips. Although I have lost a motor mount or three. I retighten them the moment they fall off. Have yet to try loctite, but hear good things.
Used the TW more to learn what the right resistance was and felt like. I couldn't tell you where my torque wrench is right now. Have read many things about proper torque. I am sure there is good reason to be more exacting. It just works for me. A wile back, I wanted to sell a tool kit just for motorized bicycle building and was going to include a torque wrench, but for the most part think they are surpurfulous. Striping, snapping and general over tightening is reported a lot though. (That might be a good thread, "common first build mistakes, we all done 'em")

Didn't mean to ramble on your thread Whoisworkin, sorry.
worst apocalypse ever

Just a suggested bit of advice to any newbie out there is to replace all the nuts and bolts on these chinese engines BEFORE putting it on a bike,engine mount bolts most importantly.Replace all the bolts on clutch cover,sprocket cover and case halves with hardened steel metric capscrews. Loctite blue on every single bolt you see. Do this and you will not have ANY problems with stripped or loosened lost nuts and bolts.Mac
