Tire manufacturer's listed tire pressure doesn't account for your bikes size and weight.
The bike manufacturer takes that into account.
Go by the bike manufacturers recommendations....

Dunlop says 33 & 36 for our bikes.
http://www.dunlopmotorcycle.com/fitmentguide_print.asp?fitment_id=621

And, "For high-speed, fully loaded or dual-riding touring motorcycle applications, inflate front tires to maximum recommended by vehicle manufacturer for Dunlop fitment and rear tires to maximum load inflation pressure on sidewall. Rear touring tires must be inflated to a minimum of 36 psi for light to medium loads and 40 psi for dual riding and other loads. Never exceed maximum load indicated on tire sidewall or vehicle capacity load found in owner's manual.

"Underinflated tires can result in imprecise cornering, higher running temperatures, irregular tread wear at the edge of the contact patch, fatigue cracking, overstressing and eventual failure of the tire carcass."
