I'll have them if you are prepared to ship them (at my cost)? Jim

Hi David What size is it and where are you please? Jim

14" NS-2R in Street compound are just £45+VAT at Demon Tweeks! The 86V XL Extra Loading rating suggest they might not do the ride any favours. Anyone got first hand experience?

When I had similar issues it was the brake line that was weak link. In the end I wired an earth from the chassis to the wing stay (riveted ring terminal) so that I could leave the repeater untouched.

I had your setup Julian and the power/feel was perfect until I started venturing on track. Then I found the pedal would go spongy and that was only cured with a bleed of the brake fluid. Another member told me this was a common problem in the Academy (2013 I think) and that duff standard master cylinders were to blame. After switching to the uprated master cylinder (which appears much better quality) my problem has been resolved. Nice firm pedal but more braking effort is required and there is a little bit more dead travel. I was happy with my old setup before it got spongy, so how about sticking with it unless you run into a problem.

This is a curable problem that I and others have had with Sigma engines. See here http://www.lotus7.club/forum/techtalk/150-sigma-expansion-tank

My 6" Sigma silencer took exactly 3 bags.

In my experieance Acousta-Fil Boa is much better than the Powerspeed packing material! I had my Sigma silencer repacked by powerspeed and the noise was a poor 100 dB static and failed the Brands 92 dB drive-by. Quick re-pack with Boa and the noise was down to 97 dB static and no more black flags :) If you buy from JJC or Demon Tweeks (same people) via ebay, you can get it delivered to Argos for collection.

Yes I used it for a quick re-pack at the Club Brands Track Day after my Sigma 150 failed on the 92 dB drive-by limit. It reduced the static noise from 100 to 97 dB. My silencer was a standard sigma one that I had converted to re-packable by Powerspeed when I found that a lot of the original wadding had burnt away. The wadding that the Boa replaced was put glass-fibre type put in by Powerspeed and was not that old (1 track day and 1-2k road mile) it did not appear to be degraded in any way. 2.5 track days later and the static measurement was still 97 dB at Outlon Park last month. I calulated that I would need 3-4 bags but 3 seemed be about right - very easy to fit - just wind rount the tube and gen I've never re-packed a silencer myslef with anything else but see no reason to try anything else, so I will always take 3 bags with me to track days, just in case.

I've no experience of ZT5s but my ZV3s were much better at 17 psi than 20 psi.

Sounds like you need them with your body shape. I am 6' with 34" leg. Glad I ordered my SV with lowered floors. I live on your side of Chester if you want a fitting trial? My car has leather seats.

I use Moris, who are very easy to deal with and cheap but sorry I can't comment on how they deal with claims since I fortunately I haven't needed to make one :) £135 seems reasonable to me. I'll offer an alternative POV to martyn... For me road cover that includes track day insurance was at least a £300 premium on road-only insurance. I'd have to do 3 TDs a year to make it worthwhile. In the first four years I did one TD a year so seperate TD insurance has worked out cheaper. Also you cannot always add friends temporarily to annual policies. My road insurers (Adrian Flux) do not allow that because I already have two named drivers (Dad and Wife) and that is the maximum allowed. This year I have actually done four track days so it might have been cheaper to change annual policy but instead, to reduce the costs, I planned in advance and bought one policy to cover multiple specific days and drivers. Moris are web-based and it is very quick and easy to get quotes and but cover, particularly if you have been quoted before because all info is saved. I've also bought from CCI but they seem to be more expensive. Jim

I used also dowty washers and it's been a case of fit and forget. The only downside of the dowtys that I can see is the thickness which means less thread engagement so you need to be careful not to over torque and strip the threads.

Great day on an epic track - my favourite so far! Many thanks to Andy for organising and Merrick for the tuition! I'm already signed up for Oulton :) Thanks also to my pit buddies who helped me with my silencer re-pack aftar being black flagged for noise. Anyone else struggled with and sorted a noisy Sigma exhaust? The re-pack cut my static from 100 to 97 dB but the exhaust boom is still irritating on the road. Generally I think track manners were excellent but we are all human and bound to get it a bit wrong every now and then. I only got frustrated a couple of times and during the day but I must have passed or been passed 100+ times without any issues. There did seem to be more traffic than on other club track days I have done (Oulton and Cadwell). I suppose this was due to it being sessioned and a sell out. Perhaps in future, we could encourage only the quicker/experienced guys to queue up to go out and the novices tag on to the back of the train as it leaves the pits? Pobably wishfull thinking when everybody is keen to make the most of limited session lengths! Jim

Seems like you still have the same problem you had last year? http://www.lotus7.club/forum/bleeding-sigma If the plug is still fitted in the top of the radiator then I guess you never got around to re-introducing the bleed-line from the radiator to the tank? This is how my plumbing has looked for the last year and I've had no more cooling issues. I recently replaced the other plastic tee and on refilling I had no problem with air locks.

I use a natty low profile ring spanner that was supplied with some flat pack furniture:

Handy thread to keep bookmarked :) I've been balancing the TBs for a few years but only got the Easimap cable this year. Since theyn I've been through the process a few time now and I'd say it not as easy as the guys above suggest. Patience is required until you get the knack! My additional tips: It is possible to balance throttle 1 vs 2 and 3 vs 4. You use the little air bleed grub screws on the top of each body. Loosen the 10mm locknut and tweek the screw as required to allow air to bleed in. I would suggest setting the TPS as close as possible to the tipping point between 1.03 and 1.04v because the setting does seem to wander a little (maybe 0.005v) over time or with temperature. I found that if set bang on 1.04, occasionally the engine would idle at the first load site (triggered by 1.05v) causing it to hunt. The TPS will move if the bolts are not tightened enough. Mine moved so that the idle was 1.00v, resulting in hesitation at low revs. The TPS body is plastic so there is also a risk of damage due to over tightening. I tightened as much as possible using the wrong end of an allen key and so far so good. When re-fitting the Air Filter, make sure the dipstick still fully engaged in the sump, otherwise you will end up with a oil leak. Luckily mine was only a minor leak and I spotted it before loosing enough to even require a top-up.

Aerobod's solution has worked a treat on my Sigma SV. That is putting a 1000ohm and 2000ohm resistor in parallel with the fuel gauge wires from the sender (giving 667ohms of parallel resistance to the sender unit). Previousely, the gauge was very pessimitic - on the red after 150 miles. Now I think it will hit the red at about 250 miles (I last filled up after 215) which is spot on. Many thanks Aerobod!

Radiators are a problem on Sigmas. The standard Sigma 125/150 plastic tanked ones fail at the seams - I went through two before upgrading to the Sigma 140 all-ally version. The problem with that one is that it has no bleed nipple. Caterham just remove the 5/16 T and the branch to the rad. I found that I was forever getting airlocks in the top of the radiator noticable by the level in the header tank rising. The solution was to use an M10 banjo fitting to create a 5/16 nipple in place of the bleed plug. http://www.ebay.co.uk/itm/10mm-BANJO-union-for-8mm-FUEL-OIL-HOSE-10x1-5-bolt-FUEL-HEAD-FITTING-Hydraulics-/281286905449?pt=LH_DefaultDomain_3&hash=item417e018e69

Andy, was the Oulton booking form supposed to be sent with the May Low Flying? There was no form with my copy. I booked Brands a few weeks ago and would also like to book Oulton.

Yes please

So is something like this that is being suggested but a 73mm version? I would be interested at that price but I think I'd want to see photos/videos of them fitted to somebody elses car before buying. For the time being I'm using LED sidelight bulbs and a buzzer for when I leave them on.

I find the strobing ones are very distracting to follow.
