--- i use shell rosmella T ...  oops i mean rotella T. this stuff is 
 meant for diesel engines which are higher compression, kinda like our 
 bikes. works great in my cummins and my klr. only down side is that 
 this stuff stinks a little when new ( rosmella is the nickname in the 
 diesel community ). check out there website, theres an article about 
 m/c oil on there somewhere. rotella T 15/40 all year.  scott

thicker the oil, the longer it takes to reach the top end.  Sure, a 
 thicker oil will leave a better film behind, but that's not the best 
 approach for start-up lubrication (the most critical period).

They open on startup because cold oil is too thick to go through a 
 filter.  The colder the ambient temperature, and the higher viscosity 
 grade of the oil, the longer the bypass valve remains open.

 oil by Motorcycle Consumer News from a couple of years ago, I believe 
 the entire series is available as a special reprint.
