Can thinner oil cause engine ticking??
I have noticed a new tick tick tick noise recently which is only there when the engine is cold. I recently switched to synthetic 5W40 oil and another rider told me the thinner oil could be a cause for this.
He said the oil probably isn't sticking to the internal parts as well when its cold due to thiness and it sounds like the noise is a dry cam chain... Any ideas? At first I though CCT but its fine when warm and at operating temperatures...I think I will switch back to 10W40 and see how that goes.

Why did you switch to 5W30?

rotella T6 synthetic was on sale and I had credit with the store I got it from, also I've heard its a good oil in bikes...previously I was running 10W40 Motul 5100 and will switch back to that...

Also its not the normal consistent ticking we get, I've been hearing that noise for over 10k miles...its a different noise and the fact that its really hot here leads me to believe the oil which is supposedly rated for colder temps. I'm in Toronto so its cold enough, but in the summer we get crazy hot days too. I ride the bike in the winter months too and was worried since my ride to school was only about 7-12 minutes the 10W40 probably wasn't warming up quick enough...

common maybe. correct? no.

he changed his oil to a thinner cold weight oil. afterward, the bike ticks when cold. seems pretty obvious to me. like a previous posted said, why did you switch to 5 weight cold? just put the correct oil in it and be done with it. the engine was designed to work with a specific weight oil. putting the wrong oil in will cause damage. it could be that his bearings arent lubricated enough. it could be the cylinder wall is not staying lubricated. basically what it means is yoour engine isnt being properly lubricated because the thinner oil flows out more easily and doesnt stay up top in the head

I get a bit of slide-slap in the carbs. It drove me crazy trying to figure out what was causing that sound.... try grabbing a stethoscope (or screwdriver) and see if you can isolate the location.
