Hey! Thanks for the response. I'm not bad at riding bikes, but understanding the workings isn't my strong point
(standard physicist, knows everything, can't do anything) so this is most likely a "seating" issue? And my best bet is to try some 5w40? Would that be a total oil change or a top up with that type of oil? Also, if I just kept topping it up with 10w60 will it eventual "seat"? Lol I obvs don't know what I'm talking about. Any help would be great, oh and I couldn't find that other post on here. Thanks.
