New Synthetic oil issues or something else?
Just got some new Shell Rotella T synthetic oil in my motorcycle, recently took apart my motorcycle because we couldn't get it to shift at all. Thought it was the shifter fork and was prepared to take apart the entire engine to fix it. Turns out it was just the shifter lever was loose and was at the wrong angle to shift.
Well afterwards I put regular oil in and it ran perfect, since we had to put a gasket seal on it and we had the engine apart my friend told me to switch out the oil after about 800 miles to make sure to get all the junk out of it, I did and switched to the rotella synthetic. Well afterwards now when I shift, not always but some times I up shift and it'll rev high, then drop about 1k rpm and then climb gradually as I increase the throttle.
Another thing, more serious is now I can down shift and up shift from neutral to 1st without using the clutch (no I don't do this on purpose, found out by accident), and sometimes when I am in neutral I can't downshift to shift the first few tries. I have to either shift a couple of times or rock fowards or backwards to get it to go into gear.
Now The neutral thing concerns me, but since I always keep it in gear when riding I am not too concerned but I want to make sure it runs properly. I do plan on selling it and don't want something barely working to sell, I am not sure if both of these things are a cause of the oil or not. They both started around the time of my oil change.
