It's tricky to say since you can only see straight through when exactly perpendicular to the curved surface, so it's probably better than it looks in the photo, but I think Rae's magical-but-vicious cleaner will do the trick of shifting more bits out of the fins.

And black paint - there's a Hammerite smooth satin black that is pretty close for touching up - not sure about bigger areas though. It wasn't noticeable on my previous bike (but only a 3x5cm area), and was still well attached after a couple of years.
Worth trying a test patch?

Rae will know the exact version. Rae knows everything.  ;D ;D

Hammerite - which one to use, Rae?
I think it was Direct to Rust satin black - i.e. not glossy.

And clean the surface, etc.

I used to put sticky plastic tape from B&Q across my radiator from just above the v to the very bottom from when they salt the roads till Spring. Also, as part of the 18,000 mile service I used to ask the mechanic to put the radiator under the outside tap to flush as much of the crap off as he could. From memory my last rad lasted around 6 years and was still working well with no overheating even with the tape onwhen I sold the bike 4 weeks ago.

I pick up the new (to me) K1600 on Thursday and intend taping up the radiator as soon as I can.

Out of interest the K1600’s use the same rad as the K12/1300’s so there should be a plentiful supply for many years to come

Heres the radiator from front on. AM I right in saying its still almost completley blocked. Theres a patch near the middle that looks somewhat unblocked. is the whole radiator ment to look like that one patch?



No one can tell if it is blocked with the pics you are posting.

As you have the fan off, get a small mirror (3 or 4" mirror from a make-up compact is good) and a flashlight. Shine the light through from the front and use the mirror behind the radiator to see if you can see through every crack and crevice. None 'should' be blocked but some are bound to be.

If you have 3 hands or a light on a stand, you can even take pics of the view through the mirror from the side. Simples!

It is OK to use wooden toothpicks/cocktail sticks to poke through the crud but don't use anything metallic. Old toothbrushes are OK (assuming you have old teeth) for lihtly scrubbing and wiggling in the crooks and nannies. Remember, the radiator core is aluminium and is easily damaged.

Also, you will have realised how much of a pig it is to get the top bolt (? Can't remember if it the top or bottom) out of the fan mount on the right hand side. While it is out, file flats on it so you can use a Spaniard to tighten it back up rather than fiddling with the screwdriver at a gawd-awful angle. Brian

Yes Rich that's the one, If it's for the engine I would paint it on when the engine is warm (not hot) about 50 C and leave it for a few days it is a slow drying Alkyd paint that once cured is very durable. Remove any loose or flaky bits and rub down with 400 grit before applying.

Keep buying Hammerite and polycell products chaps, it pays my pension  :winkthumbs: or any Akzo Nobel product come to that.

PS: if applying to casings or bits on show I would go down to 6 or even 8 hundred grit and use an aerosol version.

The K1600 rad is almost identical. The top mounts are different - the 1300 mounts are symmetrical, the 1600 are asymmetrical:
[EDIT: and even the low one looks to be a different shape]

K1300:

K1600:

The bad news is that those mounts look pop-riveted to me (from eBay):


So you may need some skill/care to replace/rework them.

But still a good spot! Will be useful to restorers in a few year's time.

Great trick with the light and mirror Brian! So after another few hrs of soaking and flushing, Id say that the rad now looks 'mostly' clear. I'll wait for the magic foam to arrive and give it another go then! The photo doesnt quite catch the right angle but its the best I could get...
I really didnt realise how just a slight change of angle changes how the fins look! ???

I'm very tempted to take off the downpipes to properly sort the paint out and also sort/replace those nasty rusty bolts.  Or am I potentially just making more problems for myself?

Ive already snapped off one of the bolts that holds on the front mud guard  :'(

Would this be all I needed- https://www.ebay.co.uk/itm/126039976812?mkevt=1&mkcid=1&mkrid=710-53481-19255-0&campid=5338365712&toolid=20006&customid=EB172397009&

I found this manual online for reference-
https://www.cyclegear.com/assets/0000/2793/akrapovic_exhaust_system_bmwk1300_rs20092013.pdf

Also a very happy New Year to you all and many thanks for all the patience and words of wisdom!

BMW have a nasty habit of coating every bolt on the bike with their disgusting Araldite-like thread lock, even the stock fairing bolts. As you found out to your cost, this also includes the mudguard bolts. Think yourself lucky it wasn't the small front axle locking bolts which can snap quite easily and are a bugger to get out when they do. I slacken mine off with alarming regularity to make sure they don't seize...of course, the first time you loosen them could just be the time they break!

That must be what it was. Luckily it was the top one, so is acccesable from both sides so should be ok to get out. Im going to check and hopefully easily remove the locking bolts ur talking about and have a look  :o

The answer to the dreaded locite is heat, get it up to 100° and it breaks the bond but I still hate the stuff.
