How to heat it up
Just been out and did about 20 miles. Great day but only 12c
The car was fine but the temp remained low, did not raise above 50c.
Heats up in the garage and fan and thermostat work fine.
How do i get it to heat up?
I could block up some of the radiator, is that a good idea?
The engine is not working as hard because of the lower weight but it will be inefficient at this temp and will proabably run rich.
Any ideas?

Where is your temperature sensor? On an R1 it is in the radiator. The sensor only sees the water that flowes past the thermostat so the engine can
be warm enough, even though the rad is cold.

Tape up your radiator bit by bit. It's actually stated in the Yamaha TZ250 manual to do this dependant on the ambient conditions as the TZ has
no 'stat. It works a treat, and that's what I do with my R1 as I don't run a stat in that either!

is guage correct? and at what point are you measuring the temperature?
the thermostat governs the engine temp; you are aimaing in the region of 90 degree but that varies a touch for different engines.

The sender is in the thermostat housing,
and 90c is about the temp for the fan to
actuate,
The gauge works fine.
As for heavier right foot, (too scared).
I may just start blocking parts of the radiator, its easy to do and can be reversed if neccesary
.
I supose its better than not being able to cool the engine.!

Is your thermostat stuck open? that can cause over cooling. Start the engine up and see if the stat gets hot before the pipe from the stat to the
rad.

I'm with Colin (Smart 51) the gauge on your dash is only telling you the temp' of the water in the radiator - depends where your gauge
sender is but that's how most work.
The thermostat is stopping most of the water from the engine reaching the rad' and so the engines water temp' is not the same as the water
temp' shown on the gauge.

If it's the Alfa engine we're talking about, almost all, from the TS to the V6 suffer thermostat problems, I'd change that.

simple, if its not getting hot the thermostat must be sticking, it should regulate flow however little the engine is working.
Don't tape up the rad, that is a sticky plaster over the problem, the thermostat should maintain running temp whatever happens.

if you were running a bec id recomend you get a smaller radiator, thinner pipes and a smaller header tank, would probably save you 5 or 10 kgs in
water and metal. I guess weight is less important with a cec though.

sorted
I found it was the thermatsat, brand new and stuck open, typical.
Put in an old one , worked no problem sits about 85 degrees.
That'll do.
