Engine Casing Corrosion

[Micky]

Sorry .... I perhaps undersold myself

What I really meant was absolute and total fucking neglect and total disregard for ones well earned possessions

Edit ... By the way russ_fae_fyvie is that structural engineer on your profile? Can't find 'strustural' in my dictionary ... sorry

Looks more like neglect to me

90,000 miles, four full winters of use and absolutely no corrosion on mine

you have too much time on your hands!

wow, russ... I thought mine was bad, that's serious corrosion

 

[rodooo]

Wee spray of wd40 the odd time does no harm. No corrosion on mine

 

[Micky]

you have too much time on your hands!

With 90,000+

Micky your bike hasn't time too corrode
The last 800 I bought had only done 4 thou mile in 2 years. It was corroded up rightly in places. My current one which I bought new is at 13 500 miles now in just over a year old and nothing corroded So I think your statement of neglect is not far wrong.

Cheeky cnut !

Sounds like a typical loud mouthed Yorkshireman spouting off without knowing anything about who he's trying to slag off.

That bike was washed every weekend and treated with 365 and WD40 but as I ride in all conditions including during the usual Scottish winters, I don't keep it in the garage and polish the engine, its what is called, normal use !

You obviously spend far too much time cleaning instead of riding.

If I can't use a bike for 2 1/2 years without getting that sort of corrosion then there is something wrong. I've ridden loads of bikes in the winter but none ended up like this.

Looking at it from a technical point of view (rather than just slagging someone off) its obvious that the corrosion has started at all the paint edges including all the penetrations through the casing. Its only the LH one as well all the others are spotless so there is obviously a problem with this particular one.

In fact BMW today offered to replace it with a new one even though its out of warranty, I need to pay a small amount of labour but it shows they think there is a fault to make the offer.

So Mickey, F U !!

Oh and another thing that points to you having too much time on your hands, checking out the spelling on my Profile, my god sir, get a life !

The pattern of corrosion on your bike is very similar to what I had; left hand casing but not the right, and radiating out from all the paint edges. I removed it and had it blasted and coated before it got quite as bad, but I didn't think I was going to get any joy from BMW, having already been turned down once. Wish I'd persevered, now.

My sump pan was also affected, in the same way, as was my starter motor.

I'd say yours had more cleaning than mine, too - but I don't believe in this "ride a bike for an hour, spend another hour cleaning it" regime.

I don't have any photos of what mine was like, which hopefully will save me from being insulted by Yorkshiremen...

Despite what Donkey Bollox above says Rodooo

R100RS 25,000 miles
R100R 30,000 miles
R1100RS (red) 54,000 miles
R1100RS (black) 43,000 miles
R1150GS 78,000 miles
R1200GSA 15,000 miles
F800ST 12,000
F650GS-Dakar 54,000 miles
G650Xcountry 12,000 miles +
F800GS 90,000 miles +

Plus as many miles on the works bikes ...
Probably nudging at least half a million miles in fifty years of motorcycling ...

None of them had any corrosion whatsoever

My dads bigger that yours !!

FFS grow up.

I see you had to put 2 posts above to try and get a reaction.


Judging by the number of posts you've made on here you obviously have far too much time on your hands, just another keyboard warrier.

You forgot the best looking one.....................the 1150GSA

 

[Micky]

You forgot the best looking one.....................the 1150GSA

You're right JB, 60,000 miles on that and again no corrosion

Three posts now knobhead

 

[russ_fae_fyvie]

Yeah whatever.

Name calling just proves how childish he is.

Getting back to the OP (instead of that purile crap from Mickey) think I'll see what this new casing looks like and if its sealed properly and will report back, at least BM have admitted there is a problem and are trying to sort it even if the bike is out or warranty.

 

[russ_fae_fyvie]

After having time to take the bash plate off today, you can see that I think I must have a Friday bike !

Not only is the LH cover a mess but also the sump,

As you can see the general condition is ok its just these damn engine casings.

 

[JohnnyBoxer]

Looks lovely..............I do like that Lava Orange

The paint bubbling is a different thing I agree with others as in most cases it was already there when the bike was first purchased, just not visible working from the inside to out. (then you do see it ). It obviously does not appear on all bikes and emerges at earlier or later times.

Just an opinion but other than abuse, of lack of cleaning and or protecting before and after certain environments. It's also luck of the draw, purchase, there are more good ones than bad, mines a good one, so far


But we all know wearing a condom won't cure the STD you already have take it up with your local BMW clinic check out the paint warranty

Just a rogue thing, fortunately It is not the norm, fair play to BMW

The general condition and how you have kept it, is looking very good. I'm sure it played a big part in BMW's decision to put it right

 

[russ_fae_fyvie]

Thats whats so annoying, regularly washed and treated with WD40 and F365 and as you can see the rest of the bike is perfect, no corrosion anywhere. Just the engine casings and all the corrosion starts from the edges of the casings and at the bolt holes. No paint has been damaged so nowhere corrosion could start, just at the edges.
I didn't realise how bad the sump was till I took the bash plate off today and then lots of paint fell out and off the bottom !

 

[russ_fae_fyvie]

This is getting more interesting !

Just found this post on an archived 650 forum about the same problem.

Think its time I phoned the dealer again !

For info guys. I had an analysis done on flakes of paint which came off the casings. Apparently this is all down to Rotax or their sub contract coaters putting a cosmetic coating on the engine instead of a proper paint specification. It would seam that they have not pre heated the casings prior to application of paint or applied an adequate primer coat.

This results in the alloy 'gassing' over time and subsequent lack of adhesion to the parent surface.

I have a full independant report on the paintwork and am now in communication with BMW for remedial action on what is essentially a paint job 'not fit for purpose'.

Report is pretty comprehensive and quite damning, so we will see what comes of it before I get out the Hammerite.

As I understand it the 'gassing' period is quite short lived, but by then the damage is done to the original paintwork and any Hammerite applied should outlast the original paint.

Why could they not have done it right in the first place? Getting a response on this from BMW is unusual so they obviously do not like getting hit with the term 'not fit for purpose'.

It or your bike ............wouldn't be the first black or grey Rotax engined BMW to suffer the same engine paint issues, so it would appear

Looking at the close -up of your sump pics, it looks like the corrosion is also spreading to the main engine block too

Let's see some close up pics of the right side (brake) too
