Thank you for the reply.(mountainmotor @ Nov. 14 2006,06:40) 502SCS,
I think Suzuki recommends 10w-40 and maybe some 10w-50's but most of them to include the Amsoil and Mobil 10w-40 synthetic shears down to a high 30wt in as little as 2k miles . Using 15w-50 synthetics makes for less shear and better shifting over the course of the oil interval .
I don't subscribe to the theory/rumors of waiting X amount of miles until using synthetic in these bike engines using nikasil bores . I have filled with fresh engine builds and with as little as 200 miles on stock engines without creating oil burners many times now .
I also don't subscribe to that Motomans method of break-in because in the nikasil bores theres not as much of the high honing ledges that can lay over if not scrubbed off which can cause glazing vs iron bores and honing of days past .
Got off topic there but was on my mind
+1 I changed to full synthetic AMSOIL after my 600mi service and the dealer said it was recomended since it is a high performance bike. Never once hade any problems and it shiffs alot smoother....06 LE with 4400miles on it now....and I use the OEM Suzuki oil filter.(Haelo @ Nov. 14 2006,12:35) Synthetic oils won't make your clutch slip.
I've had experience with car oils that have moly in them causing the clutch on my oil-cooled GS750 to slip.
But now it and and 'busa both have full synthetics and I don't have a problem at all.
(mountainmotor @ Oct. 31 2006,07:40) I will pick up a quart today and send a sample off if the MSDS shows it's primarily comprised of 1-Decene Homopolymer or has the CAS number noting same .
