A BMW service technician told me that I could use  Glysantin G48, which is the same as BMW own brand and is available as concentrate or ready-to-use.

The more important question, which you have not asked, is why the coolant has dropped down to minimum after only 850km?  My bike does not appear to use any coolant. Have you checked for a leak?

Thanks for the info Yorks_rider !
I received the bike with a low coolant level if I remember well (At least I remember being surprised to see it to low when looking some days after buying it). No leaks apparently, bike is stored in garage usually, haven't noticed anything under it, or while riding.
I saw in some forum posts, that during the break-in period, the coolant level has a tendency to drop quickly, don't know if it is true ?! :084:

I'll keep an eye on it for the coming weeks, if the weather decides to be on my side :305: !

Thanks,
Dof

I am sure ricochet Offroad makes a fine product.  I choose Black Dog because of their well earned reputation for quality of their products over a number of models of dirt and Adv bikes.  The mounting system for the F850 GSA has 6 points and no matter how hard you hit the bottom of your bike the skid plate is not going to move or get holed.  I have total coverage of the bottom of my bike from wheel to wheel.  This video also influenced my decision to upgrade my OEM plate which was more of a splash guard then a skid plate.

I finally got off my ass and replaced the some of the broken things on my bike, troubleshooted some others.
License Plate illuminator replaced, but the thing doesn't light up yet. Wasn't enough daylight left to discover why.

Rear brake indicator light switch, replaced. 40 bucks.

Still not officially fixed but I have that under control for now. The new switch is plugged in in and I'm able to confirm the source of the problem at least.

Wheel bearings are due for a swap, I'm at almost 12k miles. I've logged 6k miles on the current set of tread, not impressed with their long term road performance but they'll do for now, I expect another 3-4k of tread wear before I swap.

Haven't done an engine check yet (head clearance e.t.c).

Drive chain and related components haven't been swapped yet, I was waiting till better weather to do it. It's finally starting to thaw out a little.



Rear turn signal in a freak occurrence during an emergency visit to the hospital sheared off late at night, couldn't see what happened. So I'm running with a defective break light and one missing turn signal. :O The 'suck' is definitely going overboard this year.

Skid plate looks nice but what is so special about this one?

Ricochet Offroad makes a good product for the 850 G for 250. 5.5mm Plate. They list one for the GSA as well.

F750/850GS Main Chat board / Re: What size drive chain?
« Last post by Newguy on Today at 03:52:05 AM »
525 122 is the OEM chain that was on my bike. Before you ask about the sprockets i'll just head that off as well..
17T 44T OEM sprocket configuration.

However, when I've asked about it in various groups, you could have a shorter chain than the OEM but I don't recommend going shorter than 120 if you intend to take this off road.

120-122 gives you enough links to afford sufficient travel of the drive chain when the suspension is getting worked over by off-road conditions. BMW recommends 30-40 mm of chain travel allowance, I don't measure mine but I suspect that is a bit sloppier than I allow for usually typically; Specifically due to the chain needing to move more when the suspension is taking hits.

I'm not as hard core about off-road stuff so as far as I can tell my eye-ball chain adjustments (matched each side with a caliper) seem to be close enough for what I do.

Assuming the endurance chain becomes successful, I don't see it surviving the conditions a GS chain is meant to go through without being cleaned or lubed. The S1000 RR is a road & track show bike, never meant to get dirty or muddy.

I put the BMW HP levers on the bike



They are very nice....but I'm not sure they are worth what BMW charges.  I got them for a steal.
Hi,
How did you put the HP lever? Does it come with a mount? I got one but does not have a mount to attach the clutch wire.  Any idea?

Is it just my strange nature? Does anyone else wonder at the reasoning we protect our polycarbonate headlight lens with a piece of polycarbonate?  :084:
Particularly the BMW version.
If the protector is constructed of such a high grade of polycarbonate to offer protection. Why not make the original light fitting out of the same?  :187:

Just another layer of protection... The chances of a stone or rock crashing through one layer and damaging a $2,000.00 USD headlamp is a lot less than the bare headlamp.
