On old Carb monster 900 I was running about 12 had to push it down as bike was very hard to start and was burning starter motors for breakfast when cold.

Cold starts were basically rock the engine till you feel it is at low compression stroke, then start so starter motor can build up momentum :')

Fine on weekend bike only. There was no reliability issue during 18k miles I have done but service on valves was done every 6-7k miles max and valves were always out by then.
Also valve seats were gone at 8k miles then 7k miles after.
