well I asked the previous owner about the oil he used.
they guy who put the bike together ( the engine was gone through and redone for "longevity" apparently and only has about 7 K miles) said to use Schaeffers oil.
but when looking through schaeffers oils, NONE are Jaso MA spec. so I asked them about this.
apparently the only negative effect would be from the clutch potentially slipping, which additives/friction modifers could prevent. knowing the clutch is a wet clutch I am wondering WTF the builder was thinking...
I finally found an owners manual online through Kawasaki Australia. and apparently 10w50 is okay to use too ( we sometimes see temps above 104 here)
I think I will get the silkolene fully synthetic ester race oil in 10w50.
or I may get amsoil. don't know yet.
I have also dfoudn out the front tire is a Michelin pilot power, and the rear is a bridgestone battlax BT016.. in 190/55zr17... rather then 190/50zr17...
oh well, at least the frame isn't cracked... yet..
