It is interesting... not the oil but peoples reaction to the
zero W part... If we agree that the most wear occurs in our
prized engines during start up before warm up then a 30Wt with
the viscosity of 56 cSt wins the race to the critical crank
bearing... I don't know why but it doesn't seem to matter if you
point out that at 212ºF operating temps 0W30 has the same
viscosity of 10 cSt as 5W30 10W30 or even straight weight 30...
its like if I mention Mr.RC45 is on 10W 30 no problem... but if
I mention 0W 30 problem...


Wet clutch and that oil? Or do you have a dry clutch on the R45?

The RC45 employs a 140mm oil cooled clutch straight off Honda's 180HP NR750...

I know that oils marketed as motorcycle-specific will carry
the JASO-MA label. A properly specified motorcycle oil will
still allow for the appropriate lubrication and cooling of a
motorcycle clutch while maintaining 100% of the drive to be
transmitted by the clutch even under arduous operating
conditions... Mr.RC45's tall first gear good for 90mph
operates under arduous conditions on the street and track...
and I'm here to report that Mobil 1 either the 10W30 I
started with back in 98 or now the 0W30 I'm using has
maintained 100% of the drive of all my 116RWHP... so for all
practical purposes I think I've meet and passed the MA clutch
friction gate test...

Gorilla clutch basket, hd clutch&springs etc....

I have a an rf900 parts bike that i may swap front end & swing arm to use RF wheels & radial tires (if i dont sell this beast 1st).

out Amsoil 10/40 m/c oil
in Amsoil 10/40 m/c oil

When i bought the bike you could not shift into neutral if stopped due to under cut trans.

W/ Amsoil at a stop 1 can so easily find neutral, what was a real big hassle is no longer an issue.

Runs 10 deg cooler got 2 mpg better.

I sure would like to hear why people changed brand and viscosity.

2009 Kawai KLX250S

Bought it with 1050miles.
Drained what ever was in it.
Filled with Castrol 4T 10W-40 and ran it for 50 miles.
OEM filter.
Drained it and filled with Rotella T 15W-40.
Same OEM filter.

Suffered with hard shifting with the Castrol once it warmed up.
Haven't ran the Rotella yet.

Have just poured Valvoline XLD Classic 20-50 into my R65 with BMW filter. It's SG/CD rated, pretty hard to find these days - will do a UOA at 6,000km to see what it's like. No problems with the Castrol Edge Sport 25-50 that was in the last 2 changes (I get 5 litre packs), but was a bit worried about cold winter starts....not that I ride it much in winter.
