Sorry Jeff, can't help with bolt size. And yes, I too have read several reports here on this thread on newish DR's stating current NSU bolts are Allen head ... and that they in there fairly tight. Suzuki don't torque them down because the NSU unit is PLASTIC. Loc Tite is your friend. Safety wire it if you like ... but I'm confident Loc Tite is adequate, IMHO.
