Running Hot?

I have, as mentioned in my original post.

Ok..... and the temperatures were?  Would expect 85 - 95º on the top hose and 10 - 15º less on the bottom hose.

Generally, if you have a cooling issue and it runs up near the red under normal conditions it takes very little to tip it over the edge into a full blown boil over.  If it comes up promptly to it's usual point on the gauge and then sits there stable over a range of conditions it suggests to me the cooling system is fine.

Running very lean or very retarded tend to increase running temperatures but mostly when under load.

FWIW I have a filled system gauge on mine of tested  accuracy and it doesn't boil over even at 110ºC indicated.  Takes severe provocation to get there (usually involves Alps and slow camper vans or 35º ambient and stationary traffic).

Pity their list doesnt give insulator colours
