Cold climate oil grades

Mine's magneto and kick start.

Synth doesn't really work in the Armstrongs - causes all manner of
problems. The military spec oil for down to -15° is 15/30 high detergent
mineral.

For some reason I think anti freeze becomes less efficient if not diluted
enough - can't remember why, it may be boiling points.

Got some lock de-icer already.

Already gaitered but may look at getting some ACF50 - although I a couple
of gallons of Waxoyl which I tend to sling about quite liberally.

We have Scottoilers so fucking about in freezing conditions with a bloody
toothbrush won't be necessary. We're also camping and so I'd like to
avoid getting covered in engine oil.

Hooray for aircooled.

I'll be happy if it starts.

 

Not just in Sweden. I remember both Dad and Granddad with similar
devices on their cars in the '60's - doubled as a heater for the
greenhouse as well.

I have, 200A. Mwahahahaha! The power, the power.

Will also have jump leads 'just in case' and hope that someone else
manages to get their bike started.

Still torn between 10W40 Castrol or 5W40 Motul. Both fully synth.

Using pre-mixed 'Yamalube' coolant. Rated to -75.

From memory the freezing point peaks at somewhere and if you increase
the ratio above this then the freezing point lowers. Addtionally
there's the question about how 'thick' the fluid is. Still, irrelevant
for me.

Have a couple of (small) cans of lock deicer for this.

Replaced the fork seals this weekend and also put gaitors over them.
ACF 50'd the exposed forks but not the covered sliders.

Scottoiler with 'special' oil.

Am hoping it won't get to -35 degrees. Still my sleeping bag's up to
this (survival rated at -50) plus my tent should be fine (aluminium
poles).

Good job I fitted a mainstand since it didn't come with one as standard.

Suppose I might have an extra cuppa or something in the five or so
minutes warm up since I don't smoke.

It did, thank you.

 

The one with no minibuses !

200A - **** me. What battery did you get, and are you sure the charging
system will be able to keep up with it?

in the making, TS250C, RD400F (somewhere)
BMW E46 318iSE (it's a car, not one of those 2-wheeled pieces of shite
they churn out)

 

If there isn't a constant higher than normal current drain on the system
once it's started the generator should be able to easily 'catch up' and
recharge the battery.

We'll be covering a couple of hundred miles a day so it may not get it
fully charged as quickly as a normal battery after a heavy start but
it'll have plenty of time to recharge and, importantly, at least it'll
start in the first place.

 

There's really no reason to go much past 50/50 since that gets you to -37C.
A higher percentage of antifreeze, up to about 60/40, does decrease the
freezing point and increase the boiling point, but IIRC the downside to
using higher concentrations is that ethylene glycol doesn't carry heat as
efficiently as water, although that's unlikely to be a problem when the
air temperature is well below zero.

Fck off, you spamming ****.

 

Silly sod.

 

That looks promising. Bookmarked.

 

Can you install a second battery, in parallel, in one of the panniers?

 

it's a bog standard AGM YTX14BS bike battery - you're confusing CCA with
Ah.

The CCA is the peak outrush current the battery can deliver. Ah is the
total capacity of the battery.

Steve's battery can deliver 200A but not for very long as it will use
the 12Ah total stored power more quickly.

The starter motor won't consume any more current from the AGM battery.
It's just the more efficient chemistry in the AGM battery is likely to
supply the *required* current at the low ambient temperature. Even if
Steve runs the battery flat, the alternator will only need to put 12Ah
back into the battery to get back to full capacity.

 

There's no way in hell you'd have block freezing at -15C with a 50/50
mixture. I know this from many years of living in a place that usually
makes it close to -35C at least once a year. My guess is that they
might have made up a 50/50 mixture to pour into the system but there
was a lot of water in there before hand. If you can't drain the system
entirely after flushing with clear water, it's best to look up the
capacity of the system in the owner's handbook, put in half that much
of pure antifreeze, then top up the remainder with water. Don't ask
how I know this.

 

err No, it'a an answer to a question posed here.

 

The inside of the battery will be nice and warm, have no fear. The only
issues you may have are if the battery fluid freezes and I cannot remember
how cold it has to be to do that but you will be long dead before it
happens.

 

I followed the link to see what it costs to do Eurostar Ski to B-St-M
£160 each way standard
£235 each way posh

I suppose if you factor in the cost of the transfer from the nearest
airport it doesn't seem too bad and certainly more civilised than the
alternatives.

 

Fitting an aftermarket extra-high capacity battery would make more
sense. But from a little googling, it seems the XT660Z has a very
dinky sized battery (150x70x105) so your suggestion might have some
merit. For sure a pair of jump leads and some sort of external
combustion heat source would be a good idea for the squad to carry.

I looked up the Hawker Odyssey range but the only thing they have
that would appear to fit doesn't appear to be significantly better.

A Westco AGM one, 12V12B-4. It's still a dinky little 12AH (or 10AH,
The tayna website mentions both) .

However the Westco website specs it out as 10AH and 125CCA. And I'd
guess they're right. Serves me right for relying on data from someone
selling me something...

The charging system will, I'm sure, be fine since it hopefully won't
need to start the engine that often.

 

Strikes me as a helluva lot, actually, although certainly civilised, as
you say.

 

I used to go full pikey and use the bus to get to Chamonix with a
place on the BMC bus being the favourite if it wasn't fully booked.
There's something very entertaining about going to Chamonix on a bus
full of climbers getting pissed and discussing who wouldn't be coming
home.
