An oil observation.......
I usually always run with Motul(10-40),but had to change my oil before I went to Spokane on Labour Day weekend.I was running short on time and had a jug of Mobil synthetic car oil(15-50) sitting at home,so I put it in.
I find that the shifting is more positive but clunkier(almost like you`re changing gears with a hammer instead of your foot,especially when going from 1st to 2nd).I`m sure its not a big deal but will go back to Motul when I change the oil before I put it away for the winter.
this is my...boomstick!
Not surprising when using a 15 weight oil in the recent spate of colder weather we've had. It's definetely 10W40 season, boys and girls.
