Sold to Stef Thanks

I've now sold my 125 so I have no use for the parts to upgrade to a 150! All thats mising is the cams, uprated springs and a catch tank. I have the following taken from a 150 with about 2500 miles on the clock (bought form Mick Atree). Caterham sigma 150 throttle bodies £350 (£780 new) Throttle potentiometer £20 (£42 new) Back plate and filter £40 (£96 new) Modine oil Cooler £40 (£102 new) 4 Blue injectors £50 (£140 new) Or you can have the lot for £470 P&P whatever it costs to send, or collect from near Canterbury. May be open to sensible offers

For my Roadsport 125 first registered 2010. Owned by me from new. 7600 dry miles. Leather seats, Rapfix detachable momo steering wheel. British racing green with a yellow nose band. Standard Roll bar. 14 inch minilites. 12v socket. Taxed till April. MOT till May. Unfortunnately another toy is imminent and I'm only allowed one in the garage at one time. £15,500 .

chris have sent you a mail about the TBs

Thanks Jonathan just what I needed to know, think I'll order titons set up that way.

Jonathan looking at previous threads i believe you have the adjusters for the lap strap coming from the buckle end,is this easy to adjust in the seat as space is limited across the seat space. I wondered whether having them at the chassis end so pulling the belt up rather than across might be easier?

When I looked at the options for my seven build 3 years ago I went with the standard cc "road harnesses". In retrospect this was a mistake. The lap strap is impossible to adjust in the car, or out unless you remove the base of the seat,and in use if you adjust the shoulder straps the lap strap seems to work its way from your lap towards your chest! I'm toying with some Titon harnesses from seven speed. Has anyone got these fitted to an S3 with with leather seats and standard floors. Are they adjustable when in the car with the lap adjusters coming up from the floor? Or is there any better option. Use is for road with only occasional track days. The titons seem much more competitively priced than the cc offerings!

I was the other seven, just arriving at my new house at Elham. Only moved from Lyminge a week ago!

My year old sigma has never had any oil pressure problems, but it does have the rev counter twitch on occassions. Its never missed a beat though in 6500 miles, and always starts on the first turn of the engine.

This may help with regards to taking the engine out without the gearbox. It obviously will need modifying for a sima engined 7.

Swapped the rad on my sigma for the all metal R400 rad as used on the supersport 140. Much better than the pLastic headed monstrosity. CC gave me money off as I complained that the plastic one was not up to the job. Several others have done the same

Nearly 3 years on mine. No play evident and works as well as the day it was installed

If you speak to Caged they will make you up a bar to whatever height you need, and they are competitively priced too.

The 3.62 Quaife sierra diff which came with my 2010 Roadsport has always been an annoyance. It has had a persistant high pitched whine between 40 and 60mph and moderate backlash. I took it to R&R who had a go at it, and made it slightly better, but the whine persisted. It ruined what was otherwise a great car. I tried filling it with all sorts of different snake oil, some of which produced a short lived improvement, but it always ended up being really annoying. I started toying with the idea of forking out £2000 for the BMW diff as the only way to sort the problem. 1 was kicking myself for not taking Caterham up on their offer of a swap to the BMW unit at reduced price. As a last ditch effort I bought an old original Ford 3.92 off ebay for £20. It was dirty as hell, but had come out of a sierra with only 65000 miles on the clock. I thought about giving it to R&R to set up but it felt good so I cleaned it up and gave it a lick of aluminium paint. Bought some new oil seals off ebay for £18 and swapped them out, and then swapped it out for the Quaife 3.62. Amazement!! This diff is a revelation. There's no backlash, no grinding of cogs, and minimal whine between 55 and 60 ( at about 1/4 the previous volume). I suddenly appreciate what a great engine note the sigma has when you can hear it. It makes you realise that this unit can be quiet. It just needs to have the original internals not reconditioned parts! It can also be quiet in a metric chassis. As an added bonus the 3.92 seems better suited to the car, it makes it feel slightly more lively, All in all about £50 well spent.

Correct, comma xtreme red. Stocked by CC.

Dr Slotter you are right. On my 2010 Roadsport I used the preinstalled wires for a socket and installed the socket in the left side of the dash. Its a permenant live and can be used to trickle charge with no problem, by far the neatest solution.

Well swapped over from Caterham GL5 to the ford SAE 90 and though not silent there is a noticeable reduction in my whine, now only in a band between 55 and 65, in my view worth the ?20 spent.

Just nipped into my local ford dealer and got 2L of the 90 grade, lets hope its improves my whinning

As above, Rapfix from 7 tips is the best option, doesn't wear and get sloppy like the cc splined QR. Also has the advantage that you can put the wheel back on in any position and dial it round till it locks.

Pete have mailed you

I have recently upgraded my sigma to the cc R400 rad with the larger fan. Its an easy swap and the new radiator looks much better made. CC gave me a much reduced price as the previous plastic monstrosity only lasted 18 months! Only thing to note is the lack of a small bleed pipe on the replacement radiator, but its not needed and I had no problems bleeding the system on refilling.

Thanks to Mike's photos this swap was easy, and the new rad looks a much better part as its fully welded unlike the monstrosity it replaced. Bleeding the system was exceedingly easy and took just a few minutes, seems the sigma is much better than the K in this respect! Lets hope this rad lasts the distance

Thanks Michael that's just the info I was looking for!

Out for a blat today and suddenly saw coolant spraying up throught the bonnet vents and onto the screen 😳 Fortunately was virtually home. Guess what the radiator had developed a large leak between the plastic and alloy! Car is a Roadsport 125 less than 2 years old, so somewhat dissappointed if not suprised, having read the numerous posts on BC. Phoned Caterham, and same rad is not available, but offered money off upgrade to the R400 rad and larger fan as used in the 140 supersport. Kindly accepted their offer. Has anyone changed up to the R400 rad from the plastic monstrosity? What do you do about with the bleed hose, as there's no bleed point on the new rad? Any tips on fitting?

The standard metric chassis defintely has a diagonal in the way too!
