Drive Shaft Pinch Bolts

Can anyone tell me if these are "special" bolts, and what the proper torque specification is (2000 V11 Sport)? Quote from my Guzzi Manual: "Remove the transmission shaft from the gearbox by unscrewing the high resistance screws." Screws came out, but the screw threads are toast - looks like they used permanent loctite on them. I ran a tap throught the u-joint ends - threads look great - but I want to make sure I don't err on the replacement screws. Thanks! Mike

Yes but that "standard torque value" is for 8.8 grade bolts. It's true the V11 have a different shaft and even a different number of splines. On the other hand, both have 12.9 grade M8 bolts. I admit not knowing for certain but personally I would use the 39 Nm. I torque them in two-three steps so they get equal. Edit: I have a "standard torque value" chart from GM that I found somewhere on the Net. For 12.9 lubed, it says 40 Nm.
