I would've thought 36 front 42 rear would be ball park, but chappers will know all about R6 tyre pressures.
Chappers?

Just don't bother looking on their website for the info though. It must be one of the worst company websites out there. It'll inform you they sell tyres and er... not much else.

Fair.
At the OP where did you get a 185 section from, their site doesn't list it, only 180 and 190 sections.

Realy?
That's what I have.
Why would the manufacturer recommend something that isn't right?
Do they wear out quicker at those pressures?

33/36 does seem low. I have pilot road 2 and the recommended is 36/41 I believe .... I run 34/39 and they wear and feel fine ...
It may be worth emailing Michellin ...

It's not a particularly heavy bike, I guess Michelin would know best about their tyres, what's the Yamaha recommended pressures(found on the chain guard usually).....

I know it doesn't help much but I tend to run 36/36 on the road. altho that is Prellis if the 2CTs have a stiffer carcass then 33/36 is understandable after all they did manufacture the tyres.
Yamahas reco pressure will be for std tyre and may well take into account a passenger.

I had a 03 R6,I ran the tyre pressure at 36/36 this worked fine,if you run the rear at 42psi i found it didn't last very long and bumped around a lot,that was on diablo corsers.I have 2cts on my R1 and run them at 36/36 they work realy well and last well,and most of my riding is on the road..

I went to the shops yesterday and the bike felt really weird.
Checked the pressures and 8.6psi in the rear 23 in the front.
OOPS.
It's been really cold here and I haven't checked them for a month or so. Does that sound like it could happen without a puncture or problem?

Temperature will affect pressures but not by that much, an educated guess but I'd say +/- 6-8 psi difference max. Sounds like a slow puncture possibly unless you've got someone letting tyres down for a laugh (!?!).

I had that happen to me with my old tyre's - contisport's.
Every week, the front would end up below 10 psi. A quick pump up later and it would stay up for the next week - i never found out what made it happen though

Are you insured with Life insurance???? Is Mrs Makka wanting to cash in . 
Or it could be a slow puncture.

I'd be more inclined to check the valve and fit decent metal valve caps that seal well.

Cheers Chappers.
I pumped it up to 38 and it was back to 28 the next morning so puncture it is. The front's fine.
I'll get the metal caps today.
Maybe it's all the wheelie practice I've been doing since I got the 46T sprocket.

Or just leaky valve a puncture would normaly cause a flat tyre overnight, a leaky valve is easily cured and costs pence. I like the metal valve caps that have an inbuilt valve tool so removal an seating is easy. easy way to check is to dab some sit on the open end of the vale if it bubbles change it or seat it tighter.

Went to the local bike shop.
Yes we have one in our local one horse town believe it or not.
She sold me the metal valve caps and gave me the hot tip to spray the tyre with soapy water from a garden plastic spray bottle.
Lo and behold, a tiny hole was making bubbles.
It looked like a staple had managed to get through as there was another similar hole just above it.
It's so tiny that it had only gone down another 5psi overnight.
Now I've put some gaffa tape over the hole and am gonna try some True Blue Goo today. The tyre is gonna need replacing in another few hundred k's anyway so hoping that will hold. The whole really is tiny.
So thanks for the help and hope the tip is useful for anyone who didn't know it.
You can use the soapy water spray on the rims and valve too.
