1500 miles on this oil. I'm now sensing trans feeling rough. Bike feels hotter than normal. Possible motul has zero link to these observations. I will change out to amsoil syn as soon as filter arrives. Other factors involved as dealer completed 45,000 mile service so a lot of stuff was done. I've used ams syn for years and only do one 200 mile loop; possible observations are accurate but I'll know more after ams is back in and get back to report any observation or lack of.
