You may not be so lucky, but I had a knocking sound that increased with road speed that was eventually traced to one of the centre caps of the alloy wheels... Just took a bit of sealant to sort it. I was imagining all sorts of things so was delighted when it turned out to be something so simple. Fingers crossed you have the same luck!

Just reading your original question "is there a point to this?" It depends what you are trying to achieve. Is it better drivability and real life performance on the road, or a noticeable increase in flat-out performance at the top end? If the former you might want to look at 3D mapped ignition if you haven't already fitted it as a starting point. It transforms the torque and drivability off a Supersprint spec xflow,

If you don't get any joy they are quite economic to get laser cut from .7mm stainless steel provided you are able to make the cad templates yourself. I had to do this recently as mine is from a year when Caterham tried a different size which you can no longer buy. Total cost was about £100 plus my time, having sourced the steel offcut online.

I normally use HG Sticker Remover, pretty sure it is petroleum based but anyway it works really well

I have the same ATB and Jigsaw CWP setup in mine from my sprinting days. Also had the axle baffled and the half shafts crack tested at the same time. Good job I did as one was cracked and needed a NOS replacement.

Not trying to replace with LED, just replace a bulb (hopefully). @Paul - that's what I'm hoping but like 7_malc I've had experience of the switchgear getting brittle with age so don't want to just yank it out without checking first

This is the old style dash with the three warning lights mounted in a vertical row between the speedo and rev counter. Do they just pull out, or twist first, or do you need to unscrew from the back? I can't make it out due to the steering column and other gauges being in the way and don't want to start ripping things out to find they just pop out the front

Just adding this in case it helps someone in the future. You can tell whether you have a 110 tooth or 135 tooth flywheel on your xflow by measuring the diameter of the starter pinion. 135t flywheel = 26.5mm diameter pinion 110t flywheel = 29mm diameter pinion Quicker than counting teeth! Just to add an element of confusion, the Hitachi WOSP starter has a 27.4mm pinion offset to suit. That threw me initially but is asterisked in the website to explain. Anyway, works a treat and spins a lot faster than the original

Thanks both

I was hoping to avoid having to do exactly this!

Hi all, I'm thinking about replacing the starter on my 1700 4 speed xflow with a modern high torque unit. Looking at sites like Powerlite they warn that a lightened flywheel means the standard Ford unit may not fit (presumably different ring gear?). Were Caterham consistent in their flywheel spec? And what's the correct starter to go for? The engine was upgraded to a Steve Parker Racing unit before I bought it (was originally a 1600 Sprint) but they clearly kept the original 4 speed Escort Sport box so assume kept the Sprint flywheel. Thanks, Bob

A-ha - found it - thanks! I'd been pointed towards the wrong end of engine so hadn't taken the nosecone off, and was looking for something much smaller. Cheers, Bob

Can someone point me in the right direction as to where on the engine I can find the oil pressure switch / sender? It's a vdo unit if that makes any difference. Can't find the bugger anywhere so guessing it's hidden under the carbs? Bob

If you've got the time then fitting a Megajolt 3D ignition to it will help the tractability at lower revs no end. Made a startling difference to mine, and that is on a 234 cam. FWIW I'm getting 138bhp at 6000rpm according to the rolling road I use, and it was effective enough when I used to sprint it. It's a Steve Parker Racing unit rather than a Caterham one. Bob

Car runs fine, it's purely a charging issue. Thanks SM25T - car is booked in with a supposed 'top notch' auto electrician next week (via a mechanic who we have known for years - Jon ex-of 7 Indulgence) so it's now an SEP Thanks everyone for your suggestions. I'll report back on what the chap finds. Hopefully it will be easy, cheap, and not embarrassingly obvious! Bob
