Over torquing will only distort the head. Even that seems a little high to me but I assume he got that number from a dealer, although I can't be sure about that.
The original owner had made up a drawing of the heads and torque sequence with a 600 inch pound torque spec. If you check out the other thread from the link, I posted a picture of the riders handbook that I got when I bought my 1954 KH. Two lines in nut on Compensator and one line in clutch hub nut. Clutch hub nut (left handed threads) 60-80 foot pounds. The compensator sprocket 150-165 foot pounds.
65 ft pounds on each bolt would be an extremely huge amount of torque. The torque specs are the same as with any Evolution engine. There are eight head bolts for each aluminum head. There was some additional discussion somewhere else that I can't find right now that had some comments that 65 ft pounds was an excessive amount which I agree with. My question is, are properly torqued handle bars able to come loose in a low speed crash like he Is claiming? I plan on calling HD directly and getting their answer as well but would like your opinion.Here is a link to a previous thread that talks about head bolt torque. The dealer says not a chance I would have noticed loose bars when I took it home. I believe that the handle bars came loose and dropped on me causing my hand to roll the throttle open. I also realized that the mirrors had been installed above the bars and not below like the Forty-Eight is supposed to be so I changed them. The previous owner had a bunch of upgrades on the bike that he wanted back, including mini apes. After the crash when I was looking at the bike I noticed that the handle bars were not bent nor broken, instead they were loose enough that I can yank them up and down. On my way home after taking a turn the throttle was pulled wide open and I knee jerk grabbed the front brake locking it up. I just bought my first bike, and Harley, Thursday June 6 ,2013 used from a local HD dealer on Saturday I rode it for almost 200 miles.
