Hi Miker7
Welcome to the fun of Sevening
Given it seems to get up to temperature on the drive, I think you may find that to avoid possible overheating, the thermostat may have been removed and therefor you have full on cooling flow all the time. I know a lot of people which track their k series do this.
I know that was the case with my 1400 Supersport when I first got it, and when driving in Autumn/Winter on colder day I found I couldn't get up to normal running temperature (circa 80-85 degrees) - in winter it would show 60-70 before I refitted a thermostat.
No doubt there are pros and cons of having thermostats (especially if you're worried on overheating) , but I'm just as uncomfortable with revving the arse off (and you have to with a 1400) a too cooler engine as fear of the thing boiling. You can get various thermostats from Rimmer Bros which open from 76 to circa 82 degrees - I've got the standard 82 degree fitted and it seems to work fine, as long as you bleed the system properly - I've never come close to boiling.
The only way to find out is to take the thermostat housing off and look to see if there is a thermostat in there - of course there may be one in there and its jammed open.
Good luck
