Bike Carb Rolling Road - Essex Area??
brown_d9 - 27/4/15 at 02:49 PM

Hi there,

Our Locost is finally completed and ready for a good setup on a rolling road.

Can anyone suggest anywhere that can set up a Zetec / ZX9 Carb / Megajolt setup in the Essex area and what sort of money we should expect to pay.

I have contacted one company who seemed very rude and wanted to charge approx. £450 to set up the carbs and ignition which seemed like a lot to me, but having never done this before I don't really know whats cheap and whats expensive.

I would definetly rather pay a slight premium for a good job though!

Thanks so much in advance.

I believe ATspeed do bike carbs
I intend to go there when the 2.1 is installed

Thanks, that's where I have got the above quote for... seems like a lot of money, and the person I have had e-mail contact with dosnt make give me a warm feeling... seems a bit grumpy!

Seems a little expensive.
I would expect around £250 to £300 but that's going on past experience with injected engines. Not sure how much more (if any) time carbs add.

Carbs will add time for sure, as you need to open them up to swap jets/air correctors etc to get it right.

You could do it yourself.

With a AFR meter and a bit of time the carbs aren't difficult. As for the map I'm using someone else's base map that I tweaked and it works great.

£450 does seem a lot.

I think I might well try that, can you suggest a good AFR meter?


Thanks

I made one of the JAW kits which was OK, but I think the innovate ones are better.

I've got an innovate lc2. Really good bit of kit.
Connects to a laptop and is easy to record your afr.

Thanks guys

Does it screw into a standard lambda sensor socket, or does it need connecting to each individual exhaust pipe?

Cheers

Yes, it goes in a normal lambda socket.

alex1991 - 27/4/15 at 06:25 PM

You want to put the wideband sensor in the collector where it receives exhaust gas from all cylinders (otherwise you will only know the AFR of those select cylinders and some engines (Honda B series cylinder 3 for example) can have a cylinder that runs a bit leaner).

brown_d9 - 27/4/15 at 06:27 PM

Our lambda socket is in the manifold collector so it should work just fine.

Does it come with comprehensive instructions as to what readings we should be aiming for?

Cheers

With maybe 50..100 emails a day our replies have to be simple and short.
Bike carbs are time consuming to calibrate correctly, thats the idle, cruise and full throttle not just drilling out the main jet and saying its done.
A wise man once said that the quality of the work will be remembered long after the cost has been forgotten..

And where else do you see pre-war GP cars and CanAm McLaren's waiting to be tuned while you are there? I highly recommend Atspeed....just remember to give as good as you get as far as verbal banter is concerned
