The M8-1.25 grade 8.8 bolts securing the ring gear are torqued to 22 ft. lbs., the 10.9 flywheel bolts to 30. My experience with the Sure-Flex clutch plates has not been good - very abrupt engagement and clutch adjustment changes cold to warm.
@Amboman4 - I appreciate all your comments! - Positive and Critical. I am grateful when you leave a comment. I need to be called out if I do something wrong (and I am a firm believe that I learn more from my mistakes than my successes). I am a novice and explain that thoroughly. People, enjoy the videos, but don't use them as a step by step restoration. They are not! For some reason, your comment is not being posted. I see your comment, and I agree with the 30lbs. I saw it on the sheet after I did the video... and they have been torqued to 30lbs. However, I really lean on Chilton's manual for installation, and I mean I REALLY LEAN on Chilton's manual, and Chilton's lists 25 lbs as the torque spec! The torque specs for this motorcycle are all over the place! The variations are mind numbing! And I really follow the installation provided by Chiltons, which is the using the lock tabs and bolts, without schnorr washers or lock tight. And here is a dirty little secret. I normally slightly overtorque anyway. I am only slightly comfortable with published torque specifications, because there seems to be a wide variation based upon the sources. For example, Head bolt nuts - Chilton is 27.48 (Page 42), Thisoldtractor.com is 29 to 32 , and HarperMoto is 35lbs (source - harpermoto.com/pages/motorcycle-parts-faq) - there is a 7.52 lb differential just in head bolt nuts! That is a 27% differential... and I trust all those sources! Suggestions for other clutch plates?
The torque figures on Greg's website are from the factory manual and are the only ones I trust. Over-torquing can be just as bad as under-torquing. Guzzi stopped using the lockplates and went to schnorr washers on later models, good enough for me. For clutch plates I prefer the SD-TEC clutch kit which has 4 mm splines and comes with the hub and intermediate plate. It's more expensive, but the best IMO. @@VintageRestorations-by-WS

@@Amboman4 I would love to get a copy of a factory manual...
