Apparently someone on the GW board, I think that is where I saw it posted, was able to find out from a fairly accurate source that Honda did not change the gears, 4th & 5th, but now is coating them both with some new type process than is supposed to aid in longer life...Maybe has something to do with this supposed "ghost shifting", maybe not as I have not yet had the transmission do anything but what it is made to do correctly...I am not going to open any comments about oil usage...but, I have again been advised by people who have ridden Honda bikes for many thousands of miles, using Honda oils. to be very cautious as to what type/brand of oil that I use that has the potential to cause some issues and T6 is one of them...I have absolutely NO experience using anything but Honda oils and therefore I am only posting what I was advised....period!!!
