Mine runs the same and it's only done 2,000 miles since new - I think they are all like that (also, I think the guages aren't that accurate, from what I've read).
Are you looking for the bit that sits on the front and holds the lamp it? If so, I have one, but it has a small dent in it. Alternatively, you can buy just that part from Caterham.
Is user SKC Premier Power? For this upgrade, if you already have a full 310r are you saying that with just the throttle body change it will go up to 174bhp? Does it then need mapping or anything? What is the cost please?
I have just bought a SBFS half hood and got it yesterday - I am not sure how these side popper should be fitted? I assume the hex popper goes directly on the bodywork, but then why have I they got a double fastner, what is that for? Mark
On my 2016 there is a blanking plug un the passenger side knee panel. Remove the plug and the 12v socket fits straight in the hole and the wiring is already there in the loom (cable tied up) so you can connect straight into it.
