I recently switched from using Suzuki synthetic 20W-50 to Motul 15W-50. I think 4T. For those of you who say engine oil doesn't make a difference in shifting, think again. My bike now shifts like my B-king or CBR600RR. It shifts so damn nice, I can't believe it's the same bike. Put about 100 miles on it today. never missed a beat. Even 1st-to-2nd. And it found neutral every time, with no histrionics, like it has had recently. Don't think I'll ever try another oil in this bike. Less than 250 miles to 40,000. I changed it about 700 miles or so ago, But today, I noticed how well it is shifting. Also using the K & N filter, which has an 11/16 nut on the end. So much easier than using a damn filter wrench or one of those damn cup things, which always seem to get stuck on the filter.
