You know I never thought of the oil weight before. I ended up using Mobil 4T 10-40. Maybe you're right because I live in SC and we have been having some low 90's and very high humidity lately when the shifting has been delayed. I noticed when I rode the other night in the 70's I never had any delayed shifting. So maybe the oil does need to be thicker during the summer. maybe I need to run the 10w-50. That may be the problem.Your oil level should not have any effect on you're gear change because it's not like a normal bike where the dip stick is in the gear box and oil levels are critical .the spyder has a reservoir oil tank and it is pumped from there into the engine and keeps it at a constant pressure so the only way the level can effect your gearbox is if it runs very low and the pump has no supply ,this will put it in limp mode.the thing that will effect it the most is the type of oil you use .the temps where I live only go below 20 for about 2to3 weeks a year and go as high as 40c so I found that using 10w50 was better for gear changes and for the engine ,by doing this I don't get oil in my air box now and I burn less .this is something that brp can only guess because they don't know where you live .maybe you might even need to have different grades of oil for summer and winter to improve your gear changes.just my thoughts from the other side of the world and hope this mite help.
