Hi, folks.Have been searching on this for a while, but with all the references to horsepower and torque, I can't isolate information about torque tightening specifications. I recall reading somewhere that some people had discovered loose bolts in important areas, so I am looking closely at things as I conduct the first service. Guess what? Yup, I have loose sump bolts! Not sure how many yet, but I have tried two so far and both were loose enough that I could turn them with just finger pressure on a socket. Disappointing!Anyway, I'm going to use thread locker on any loose fasteners, and I want to torque them to the proper spec, but I am having trouble locating the specs! The factory workshop manual refers to the "correct" or "prescribed" torque specification dozens of times, but doesn't seem to contain the actual specs anywhere (other than a few places for mirrors, hand guards, etc., cause that's what's important, apparently). Does anyone know where to find the table of specs they keep referring to? I'd really like to get these right.Thanks for any assistance.Cheers,ShaunEdit: I just found another copy of the manual that has the "Generic" torque settings for each size of bolt, so I assume that this is what they are referring to. Should be good with this, although it would be nice to have specific values for engine parts.
Thanks, Phil.Yup, I found the generic values at the front of the manual, but it's the first time I have seen a motorcycle manual that had only the generic values. As you say, it should be fine. Just not what I was expecting.Now, I get to go find out what else is loose! 🙄Cheers,Shaun

I have Moto Guzzi manuals that call out "lightly oiled" on torque specs.
The rule of thumb is to reduce torque by 20% when using thread locker.. but that *is* a rule of thumb. Guzzi torque specs may or may not be correct, to boot. The only place I use a torque wrench is engine building, FWIW.

Hey Shaun, Congrats on the V85, glad you like it, that's a big change from some of the other bikes you've had in the herd. I share your opinion and experience with the manuals in regards to the torque specs in the modern manuals. When I first started working on guzzis a few years back, I accumulated many different manuals and much reference material for my CX100. Almost every single fastener had a recommended spec. Fast forward working on my CalVin, Griso & V11, it seemed the newer the model, the harder it was to find the OEM recommended torque spec. I've gathered a ton of reference material, but it's all in PDF, so it's a pita to edit and manage properly, fwiw. Over time I've come to rely on instinct & common sense ie smaller wrenches, one finger, lighter touch etc especially when it comes to the fragile valve cover & sump bolts. I like having a good selection of old fashioned beam torque wrenches ie, 1/2",3/8",1/4" drives on hand, to give me a point of reference for the force I'm actually applying. Good luck with the new ride, wishing you many safe miles And no stripped bolts, lol, Kelly
