Just to confirm 29 in front and 26 rear for the pani? on track

So ive decided to track the Panigale this coming sunday at Barber motorsports. I am required to change the coolant for distiled water or water wetter. Anybody done this before? I havent looked into it but just wondering, how much time does it take to do such thing.
I will be taking the mirrors off and taping all the lights etc. I remember changing the coolant in my 848 but dont remember the details exactly and if I had to pull out all the fairings.
HI Luis,
Here's a vid on pulling the fairings (you'll need to pull both sides), drain on left side low radiator,
Headlight Fairing Removal
Filler on the right side. So when you drain all your coolant out (don't forget the overflow tank) you'll add the water and water wetter (I think about 4 oz to the gallon, use distilled water as you don't want any mineral deposits building up). Do all this with the bike cold.
When refilling, fill thru the radiator cap. Take your time and you'll have bubbling as the air goes out. Once you get it to the proper level, gently squeeze all the big radiator hoses, this will trigger more bubbling out the rad cap opening, this is to get rid of as much air as possible.
Haven't looked at my rad yet, but you should have a bleed screw on the left top side of the radiator, open this to get any other air out and then close.
Don't forget to fill coolant overflow tank, fire the bike up watch the level thru the radiator cap (ie leave the cap off) keep an eye on the temp. YOu'll probably have to top off the coolant level a bit, you also may have a bit of bubbling, that's any trapped air escaping the system.. Cap back on ride it around and watch the temp.
Going forward I'd highly recommend getting one of these,
can do the whole thing in about 20 minutes:
Amazon.com: UVIEW 550500 AirLift II Economy Cooling System Refiller: Automotive
I don't like to leave water in the rad after a track day, so I'll drain and put coolant back in as I've my doubts about the anti-corrosion protection of water wetter.
Sharkskinz told me they are at least two weeks from having a marketable glass product. It is apparently a pretty complex fairing to reproduce.
Can anyone recommend tire pressures? The official Pirelli track tire pressure sheet does not yet list the 200 series tire.
FYI, I highly recommend getting a can of spray silicone lube, spry the rubber female fittings that enable the male tabs to slip in easier.

Got my ready for tomorrow's track day at Barber.
It is a pain to change the coolant, you have to remove the front fairing as well as the side fairings lots of tabls and rubber plugs to keep track of. Once the fairings off very straightforward.
I drained the system and then used the vacuum bleeder I've listed elsewhere which reduces the risk of getting air trapped which is always dodgy on a two radiator system.
Unlike my streetfighter I didn't see a bleeder port to get out excess air. Not really needed. Easiest way to insure the air is out is to top up the system, leave the radiator cap off, gently squeeze the radiator hoses, two you can get to, one on the left and one on the right, as you squeeze you'll note air bubbles coming out the radiator filler port (note this is the main radiator, NOT the overflow tank). Keep doing this and topping up as you go. Once it doesn't seem to be going down anymore, put the cap back on, top up the overflow tank, that cap back on. Then fire up the bike, run it for a few minutes and watch the guage, if you've got air trapped it'll go up very quickly. If this is the case shut the bike down, let it cool and then carefully open the radiator cap and repeat the squeezing, adding coolant process. FYI, the coolant circuit is approx 2.3 liters or.61 gallons.
Button everything up, put all the bodywork back on, tape lights and you're ready to go.

Regarding the headlights: pulling the fuse for the lights on the base 1199 also kills the dash.
here is my setup at the moment:
Track temp 117
ambient temp 75
Running OEM Supercorsa SP ( yeah great tires, but they are what they are )
Cold tire pressure: 23 Rear; 27 Front
HOT tire presure: 26.5 Rear; 31 Front
Tire temp: 169f Rear; 141 Front ( going slow ) not stuffing the front in.
Sag: 25 Rear; 40 Front
Damping:
FC 10; FR 17; RC 16; RR 17
DTC 3; EBC 2; ABS 2
Not on my bike, it must be special!
Seriously, I don't know who started this rumor but its not true. This is what i do and I have a dash!
My BAD!! I just realized you guys are talking about a BASE.. Sorry. Not true on the S
It was me who started the rumor. Apologies accepted.
Dr.J, do you think that the sag #s will translate from your S to the base?
Your tire pressure recommendation seems right on the mark. I ran 32F and 28R hot (45 minute heat soak w/ warmers) on a short, slow track with pavement that was not very abrasive at all. I was going to drop it down a bit before fatigue set in and I called it a day.
And my impression is that the stock tires work very well for trackdays. I'm not going to think about swapping them out for DOT race tires until the stocks are shot.
Was at Thunderhill on an unusually cool day this time of year - 77* day 1, 80* day 2.
Day 1 - I was on the oem supercorsa sp's and ran 26f/23r. Did about 40 laps and tire wear was significant but even. Was very happy with these both in terms of performance and wear.
Day 2 - Ran the supercorsa sc1's 23f/19r. Temps got up later in the day and saw signs of significant wear after about 20 laps. Bumped up pressure in the rear 1psi and made small suspension adjustments. Lap times were decently faster on day 2 and after about 50+ laps the entire left side had significant wear and some slight hot tearing. Got maybe half a day left in the rear before replacement is necessary. Very sticky tire but way too soft IMO for the Pani's hp and torque.
