NOOOOOOOOOOOOOOOOOOOOO!
Absolutely. In the meantime do not turn it over, even accidentally!I just assembled mine and torqued them to 32...disassemble and retorque?
See article 165, Page 98 in "40 years on"Absolutely. In the meantime do not turn it over, even accidentally!
Only kidding. If the heads seal and work with 30 ft lbs on the hollow setup, then 32 ought to work fine on the solid setup.
I guess the increase to 40 with the upgrade to solid is still well within safety margins and is a bit less likely to leak.
I recall having similar discussion with one of the the S Cal members. His Rapide has the early hollow studs. I quoted the KTB torque number to him, which at 30 ft lbs is the same as Richardson and the Instruction Sheets. He was horrified at that number and claimed 15 ft lbs would be absolute max for that connection.
After that I felt a bit uneasy about running these at 30, but have had no problems to date.
This was put in perspective recently with a discussion of Norton Commando head bolt torque. Those get the same 30 ft lbs but some are only 3/8" studs threaded about 1/2" into aluminium with a fairly fine 20tpi thread.
Those do let go on occasion, but even the early Vincent type bolt connection must be twice as sturdy as those Norton head studs.

Not really enough, there are two distinct connection types.See article 165, Page 98 in "40 years on"
PEI himself. "..don't use much more than 35 pounds feet on a cold engine".
Nuff sed.
Delboy.
1951 Riders handbook makes no distinction between bolt types. Some 1300 hollow ones in use by then according to the Paul Richardson list.Not really enough, there are two connection types.
He was probably referring to the most common later type.
