it is the best like i said before but watch what on eyou use because i know for a fact that the series 2000 20w 50 cant be used in an engine that uses the same oil in the clutch because its too slippery and your clutch wont work

 

hey i thru that 10w40 in...i redlined at 85 in first...my clutch can't hold anything....lol that ****s good...im puttin heavier springs on the clutch in the morning

 

What?

 

i put in the 10w40 amsoil into my 06 cbr with 4500 miles....and right off the bat something seemed really wrong...even from stoplights on occasion. So sure enough you can feel the clutch slipping with the amsoil in.

 

the 10w 40 shouldnt make your clutch slip

 

Mobil 1 full syn with honda filter best combo i think
