Hi Pieman,
Thanks for the heads up on the jet sizing..
I have had a look today to get some others ordered for when I book the Dyno run and also seem to get some some shims. (the Jenks guide didn't list I needed these for the 06, so I never ordered any to start with)
I managed to sort out the proper Keihin part numbers for the jets;
Mains being 99101-393-size
and pilots being N424-25B-size
But I am having issues on the forums and internet finding a proper Keihin part number for the shims !! the company I have ordered stuff off are OK as long as I can give them the Keihin part numbers as they don't list the CVK36 carb... Can anyone help?
I have read elsewhere on the forum that it is best to use genuine Keihin as they are ground and not punched..is that right?
The Jenks guide also says the 06 needle (code NFCD) is different to the earlier stock ones (code NAGB) and does not need changing to the Thruxton one (code NBTZ)... Can anyone help on this? Has anyone else had any experience with an 06?
I don't want to bother paying out £17 for new needles if I don't need to..

I don't know whether it's leaking a bit of air or not. But I'm sure the idea in my head that it's not sealed will nag me enough that I'll pull the whole box out and neatly reseal the gasket.

When i did mine i used the same sealant as triumph use. I am sure that a silicone sealant will do just as well. I cleaned the oem gasket up and scrpped of the original sealant first. Screws come out easier the 2nd time!. For the tricky suckers some thin vice grips work well if a bit tedious. The screws when removed can be shortened and filled square on the heads then you can replace with a small spanner

Hi
I would be very grateful if someone could point me in the right direction with my questions above?
I have searched but cant seem to find the right level of info..
I apologise in advance if this is the wrong place to post this... If I would be better starting a new thread let me know.
Thanks
Alex

As you guys are talking about re-jetting after removing the air box baffle, I assume a re-map would be necessary for EFI bikes?
My bike is stock at the moment (except for AI removed), but will be installing TORS and would like to remove the air box baffle next spring. What map would be suitable for a 2011 Thruxton?
Thanks!

TTP EFI performance tune 2 probably, although if you're going to remove the baffle you might as well get rid of the intake snorkel to get the full benefit.

Hi Jayell,what is your concern about O² sensor removal? They are only operative for 0 to 6% of the throttle, plus the fact that in the new tune the fuelling is optimised so doesn't need the correction factor of these sensors.
PS Just noticed that TTP have put up their tune prices a fair bit since I got mine.

I have the right side cover removed and the baffle removed. I cleaned up the sealer on that right side cover but I have to admit I didn't find a gasket. I'll check the service manual when I get back home.

Wow the Haynes manual barely mentions the air box. No mention of a gasket on the right side at all.
