Just got a case of Amsoil Formula4, 4-Stroke Power Sports, 0W-40 Synthetic. Says that it's, "Wet clutch compatible."
I have ridden in 20ºF and colder this past Christmas and part of January, but it's much warmer now.
Guess I'll be OK, huh?
Thank you!

 

i'd definetely say that amsoil is the oil to go with

 

+1 on the amsoil. only thing i use
