If they're standard bolts, they should be fine, but I tend to be paranoid about things breaking and causing a crash at highway speed. |

Well, nothing "happened" when I finished torquing them. I'm assuming that if I did something to them I would have known when I went too far/applied too much torque?

Don't take that as gospel, though. The torque value the service manual gives for the oil filter casing bolts will snap them like twigs. |

For that bolt you would want to use a 3/8" ratchet gripped at the end to get it "snug" if you weren't using a torque wrench.

https://www.revzilla.com/assets/0001...me_sliders.pdf They're M10 screws according to this guide. I torqued them to 54Nm (actually about 52 because I used blue Loctite), which using my click torque wrench, I had to put a considerable amount of force on to get to 54Nm. I don't THINK I did any damage, but who knows. Does that torque pressure sound right? God, I really hope I didn't do any damage. It does look more like a M10 - it has a 12mm or 14mm head then? 477 inch pounds or 39.8 foot pounds is the English equivalent to 54 Nm. The chart said 51 Nm for an 8.8 grade bolt, so it's real close. For that bolt you would want to use a 3/8" ratchet gripped at the end to get it "snug" if you weren't using a torque wrench. |

It's not a critical bolt, so "snug" is most likely adequate. You need to get a feel for how tight to make bolts. The smaller bolts can be tightened with a 1/4" drive ratchet, and medium bolts with a 3/8" drive ratchet - but not using the very end of the ratchet. The chart says 10.5 Nm (88.5 inch-pounds) for a M6 bolt of a pretty much standard 8.8 grade. There are numerous times where trying to reach the actual torque value listed in a service manual can cause problems. There have been instances of CBR owners breaking smaller bolts (M5 or so) when torqueing to the recommended spec. My son replaced a sprocket on his cycle and the factory torque spec sounded to high too me, but he tried anyway. Stripped 4 before he stopped (I would have stopped him after the first if I were there...). Had to replace the sprocket carrier and torque to a standard spec instead of the "over-torque" factory spec. https://www.revzilla.com/assets/0001...me_sliders.pdf They're M10 screws according to this guide.
