Hi All,

Just wanted to say hello. I've been taking loads of advice from the website so intend giving a bit back. I will soon start breaking down the BMW R27 and intend keeping a website to document the re-build. No doubt I'll be seeking heaps of sage advice from the forum. The site can be seen at BMW R27 Home

Cheers all,
James

James -Very nice...I look

James -

Very nice...I look forward to your posts and restoration photos. Take plenty of them...you'll need them later!

Do you know if the green color is original? My R25/2 has been repainted, but the frame is still original green paint. See my gallery picture. My bike was a police bike in a small town in Germany. I got papers with my bike which provides some of its historical trail. Also, Andreas provide me similar information as to build date and where it was initially delivered.

I also will be tearing my R25/2 down for overhaul. Probably not this winter, but maybe the next.

Apparently the bike came into

Apparently the bike came into Ireland from the dutch army in 1973. I have the original registration documents and got the Production and delivery dates from Andreas. He was able to tell me that is was exported to a dealer in holland but i lose the trail at that point until it arrived in Ireland so can't be 100% about the dutch army story.

At the moment it is green and looks better in the photos than in reality. It is crudely handpainted, had been black at some point, and my intention is to redo it in either Dover White of Black. I'm not too sure yet but know that I am not fond of the current and possibly original green colour.

i am happy in so far as it is very complete and starts on the 2nd or 3rd kick from cold. The rubber parts are quite perished but otherwise it is in pretty good condition. The previous owner had all the receipts for items bought from Uli's in Germany and actually had all the main work already done. It is just very rough looking.

i was never really into bikes and recently started looking for a restoration project. I was originally looking for a triumph when I came across this bike and just loved the look of it.

James -

I see that the spam filter snagged it. I have a few "privileges" so I toggled it as not spam. The filter tends to find proper names, etc., and thinks things are spam.

Update

I have completed the tear down and have updated the photos to BMQW R27 Home Pages

The parts have al gone to the painter. I decided to have the bike painted rather than powder coated in the end. It is going for blasting tomorrow and the painter is getting started directly. He reckons I will have everything back in about two weeks. The painter is local to me and normally does choppers. Here is a look at his pages I think he should do a fine job with plain black and pin stripes. I need to give him plenty of pics and the rough dimensions of the stripes (if anyone has any good info/drawings for these it would be much appreciated) from the info I have gleaned here.

I have ordered the i-tool, generator puller, clutch installing tools and shock compressor from cycle works as I have gone so far with the engine strip down and can go no further without making a mess of something, not having all the proper tools. Again any info others experience can provide with the R27 would be much appreciated.

Fasteners have been ordered from the bolt guy and a ton of parts have been ordered from ebay, Uli's, and others. Looking forward to all the parcels arriving in the coming days/weeks.

So far this has been fairly straight forward. The re-build should prove a bit more challenging no doubt!! Looking forward to it tho!!

One point I would like to get an opinion on is a crack in the head from the spark plug hole to a valve seat. This head was sent to Uli's to be rebuilt by the previous owner not that long ago and I would say was like this at that stage. The valves and seats were replaced also then. Is this going to be a major problem or should I just go with it as it is? Have a look at the photos at the bottom of This Page Click them for large versions.

All advice appreciated.

Check out Duane's page where

Check out Duane's page where he talks about cracks coming out of the spark plug holes. Apparently they weren't a big concern on the twin cylinder bikes.

That explains the carbon

That explains the carbon build up on the exhaust valve stem, as far as the guide, and also, inside the exhaust side around the rocker especially under the removed spring. I think that for now I will clean it through, may even walnut blast it, lap the valve seats and keep an eye on it.

Good info there. I had seen Duane's site but not that specific page. Even though not great news it suggest to me just to put it back together well and go riding.

You, my friend, are my hero.

You, my friend, are my hero. I am in the slow and patient process of trying to build a R27 which I have only the drivetrain and frame for--so your excellent photos have already answered a pile of questions I have regarding what goes where, what bolts on there, etc.
THANKS for your website.

Update

Got everything back from sand/soda blasting today and I am generally delighted with the state of the metal. there are a few issues but nothing too major. The hinge on the rear part of the rear fender is gone. You can see the previous fix here It had a bit of aluminium tube in between the two outer parts of the hinge and a bolt through the lot. The entire section of fender was held on by the two side dome nuts. I need to replace the centre stand stop brackets and have a bit of sheet metal work to do, also some work on an old repair to the front brake hub housing on the front swing arm. The man I have doing the painting normally builds bikes and he is happy to do these repairs for me. link

I was not so delighted with the valve covers and cylinder head as they came back from soda blasting. The were over-done in my humble opinion but looked a lot better after going at them with a bronze brush on a dremel tool. What do you think? I think they looked too dull, and now I hope the shine will disappear with a bit of riding and will look more dull but not satin. You can see a before and after of the valve covers, rear drive part and front brake hub here. I should have just cleaned these by hand I reckon. Link

You might try WD-40 and

You might try WD-40 and Scotchbrite pads or also try using NeverDull. Try a little area first. It might return some of the aluminum color.

Update

The correct tools arrived so I have taken the bottom end apart to get at the slingers... they are full and overflowing!! Glad I decided to do this. I have them cleaned out. The crud in there is really difficult to get out - it took about an hour as it was so compacted. There was a lot of dirt in the case against the case walls etc. There was no indication of anyone having gone in there before. No marks from anyone going at it etc. It all cleaned up nicely. I am going to replace the bearings due to the amount of crud I found and re-assemble.

Regarding the armature, I was wondering if anyone had any opinions on the state of it. It smells a bit burnt and looks a bit "crispy" in places. Are these generally robust items that can take this sort of abuse or would you think it should be looked at further? I was going to give it a light brush and clean where the brushes make contact, put it back in and see how it performs.

RE: armature/rotor...sounds

RE: armature/rotor...sounds like a good plan. I've not heard much about them being a problem. Mostly it seems to be the coil or possibly the switch plate. With the rotor, it's "outside" the engine and can always be replaced later.

I haven't posted for a while.

I haven't posted for a while. For those interested the updated photos of the rebuild can be seen here. i am waiting on the tank and front and rear fenders to come back from the painters to complete the build. It has gone back together much more quickly than I thought it would, looking forward to hearing the engine again!

James
