Friend has a SV-650 and changed to a Castrol 10W-30 from 10W-40...don't know the specific make. He had always used but since he started using the 30 it isn't running well...sputters, backfires, sluggish, etc. I told him to check his owner's manual to make sure it meets all the oil standards for his engine...he believes it does.
If it does could the fact this is the first time using 10W-30 oil be the problem?
Keep in mind this is a SV-650 motor.
