2007 Repsol oil question
Just picked up my Repsol 1000rr today, and I was reading through the owner's manual and had a question.
Unlike my F4i and 954rr, this bike wants 10W-30 motor oil. I have been using Repsol 4T full synthetic 10W-50 in my 954rr.
Will that be too heavy and maybe even sap a HP or two, or can I continue using that when I get to my first oil change(which I do really early to get the crud from the breakin out of there)?
I live in Atlanta where it gets pretty damned hot, so is that 10W-50 ok to use, or should I try and find another good 10W-30 synthetic?
There are plenty of 10W-40's to choose from, but not a lot of 10W-30...
