i've got motul 15w 50 to put in mine this time round, i know its better to warm engine up for 20mins before dropping the oil but will i still be ok doing it with engine cold ? ie should i leave it to drain overnight? its just i have got all the bodywork off, tank off etc etc and ive still got work to do elsewhere on the bike, but i really wanna get oil and filter done and dusted so dont see the point in building it back up, just to start it and warm it then have to strip it all down again. Any recommendations for doing this procedure 'cold' ??
