I have an 02 426. I know you need to check your oil after the engine is warm. The manual also states that you need to warm up the engine before you change the oil. I have a small logistics problem...I really can not spend family time working on my motorcyle. Since I ride 2x's a week this already chips into family time...so working on my bike is not an additional option. Family time is defined as when my 21 month old daughter is awake and I am not at work. So my dilema is...if I have to start my motorcyle and warm up the engine to change the oil during non-family time it will wake my daughter...thus making my wife extremely angry. Not a good thing. This rules out very early morning and late evening oil changes. Are there any draw backs with changing the oil with the engine cold? Any advise would be wonderful.
