Decided to change out all coolant hoses just for the heck of it, found a couple of issues.
1, Honda hoses are extremely tight fit, even with silicone spray applied liberally.
2, My hose to left head had been worn through considerably on top side where it touches carb manifold.
3, There is a 5mm hose from thermostat to left head, this was as hard as, I could not make an impression with fingers and thumb.
4, This is a job which should be undertaken when time is available as it is time consuming, carbs have to be removed along with most Tupperware, although with the age of 1100's I would recommend it be done sooner rather than later.
