Google translator Hello gentlemen. I have a motor after refurbishment and I want to change the oil. Now it is Motul10w40 and is it good to give this one with a photo? And then do you have to rinse the engine? Is it better to pour Motul again? Thank you.

after putting a new timing chain on my ttr250 2004 model as it was stretched, and it has been starved of oil on the head due to the blanking bolt being left in (sounds nice running still) I thought that maybe the excess heat on the valves and cams had killed the stem seals ( but it doesn't smoke much on sta...
