Title: HOT
Post by: revd on September 08, 2020, 02:52:46 pm
Yes, I did not take the linings out.  Reminds me how long it is since I last road in London.

Managed to get into Central London with ease, bike is running fine, did not over heat. Like ChrisCanning I had a warning light come on, fuel range 45 miles and dropping rapidly!  Put 15l in on the way home, bike has the fuel cap mod with extra holes.  Works out at exactly 35mpg for mixed town riding and one motorway blat. 

The bike handles fine in traffic, slow speed throttle is fine if you feather it gently and are smooth.  There was a touch of transmission "lash", but I presume it is all within tolerances, just me not used to a shaft drive.  Felt smooth changing up and down, did some clutchless changes up, blipping on the up change it was snick snick snick smooth as you want.

But yes, it was boil in the bag hot. Goretex is fairly breathable, but I'd rather sit in a sauna for this sweat effect!

Aha I always forget for a few trips either side! And now I have an actual mesh summer jacket that's 2 more times I over or under shoot with using or not using that one.

Glad it's behaving nicely.

Wow, those K1200Rs are expensive to run!
Is it the 1200 engine, or maybe the lack of fairing?
Or the revving of the Rev?

I get 48-52 MPG on my K1300S on most rides.

Mainly urban riding and heavy traffic in London.  I'll find a better picture going to Canterbury and back Saturday. Also going to Pembury near Maidstone tomorrow, so again, more open roads and I'll be good...

You're calculating it as opposed to believing the on board computer yeah?

I didn't reset my GS computer for our little jaunt on Wednesday because it takes about 8 bloody mouse clicks to get to it.

I use Fuelly.com to keep track of my mileage and servicing costs etc... works for me.

Good point. It's sure to be a few percent generous, since the speedo is, but it's not 50/35 wrong ( i.e. 42%).
However, revd may also be using his optimistic computer too.

Thinking about long-term ownership of the two bikes:

10k miles at 35mpg = 285 gallons = 4.5 * 285 litres = 1282 litres at £1.15 each is...
- £1474 on petrol for a 1200

10k miles at 50mpg = 200 gallons = 4.5 * 200 litres = 900 litres at £1.15 each is...
- £1035 on petrol for a 1300

The difference would pay for the 6k service you'll need in those 10k miles.
What mpg do other 1200 owners get? (I think 100k Martin said 42mpg?)

Far too much maths going on there. I'll just ride the thing.

Hah! I used the same calculations to say "screw it, 25mpg car at 5k miles a year makes bugger all difference to a 40mpg one, let's get a V8!" :D

K12 43.0mpg, computer 6.9% optimistic
K13 47.4mpg, computer 4.7% optimistic

I fill up when it's empty which is about 270 miles from my last fill up.

Oof i'm getting close, 220-240 miles :D

I can't remember exactly what my K1200S did but it wasn't significantly different to the K1300S that followed it so around 45 - 49mpg.

My K12 was within a whisker of the K13. It did much longer mileage trips than the K13 has but I doubt the difference was more than 1 mpg.

Not zeroed the mpg readout on my K13 since the day it arrived four years ago.

Currently showing 54.3 mpg.

 Could be my supreme mechanical sympathy - or inbuilt genetic Yorkshire frugality and a hatred of letting the moths escape from my wallet.

Excellent!
I confirm you can definitely have fun at 54mpg.

56-57mpg is on the edge of abuse, though. I've been there on a day-long group ride, and it's a bit steady. Not unpleasant, but a waste of a K.
