the point in using oil for a diesel in the bike is that it has no additives like detergents or friction modifiers. there is less reason to use Rotella in our bikes since we have a dry clutch, but it's cheaper and just as good. if we had wet clutches the oil additives, which are there to cling to moving parts and lubricate them, would also be lubricating your clutch surface, which you would not want. Use the 5w-40. it has the lowest initial viscosity (the 5w bit) so you get quicker oil flow on start-up and lower overall 'drag' from teh oil, but it also can withstand high heat (the 40) so the engine wont suffer from oil breakdown if youre stuck in traffic.

if you want to really go silk purse then the 0W-40 synthetic from Mobil is the shizzle (it has additives though). it's what comes in Porches for just those reasons. downside is 7 bucks a quart.

google oil and morotcycle and spend your life sifting through the tons of hits.
