It sounds like these are low production number custom parts.

That pretty much sums up BMW.

Worth some coin to a BMW collector though, and they often have deep pockets.

http://forums.bmwmoa.org/showthread....-4-Valve-Heads

I was very lucky to stumble upon them.. After I got my bike as with any thing I own I like the sports models.. Usually alittle more HP and more fun to drive..

The Stock RS is all ready the sport model but when looking at upgrades I was thinking boy wouldn't it be great fun to make a 4 valve head..

I then did a search and the Krauser 4V heads came up.. As did a turbo charging kit..

Anyhow I put in my searches for ebay Krauser heads. And a week like it lit up.. So I emailed the seller and asked what was the reserve he said 1000.00..

I figured I could never afford them so put 1000.00 and I won.. Never expected to.. And it was pretty complete.. Overall it should be a pretty straight forwards install..

I have new cylinders that need boring but got the cylinders for free and then there is a matter of piston rings and the damage to these shafts, as well as a broken valve spring.. I mean overall not to bad.

The kit new as just over 1000.00 back in 77 so to get it for 1000.00 seems like a good deal for 20HP more..

Harley rockers are often welded. He mentions the Stoody rod he uses. (Tatro has many worthwhile videos for those into HDs.)

Jenn, there's a guy from around here who works on nothing but BMWs--has done so for over 30 years so he might have some ideas. If I can find him in the next couple of days (he's semi-retired now) I'll see what he has to say...

Lots of the older airhead guys believe simple is the best.. You mention Krauser heads and they look and walk the other direction.. The Krauser heads can be finicky and most people don't understand how an engine works though they work on them..

it takes someone with an eye on details like valve geometry, porting and polishing and combustion chamber volumes.. Right my alley..

Very low.. They were developed mainly by 2 people.. Krauser was a big producer of luggage and racks for BMWs and a few other bikes then also went into making his own frames and custom parts..

I have always been a fan of European engineering.. My first real car was a 1970 SAAB V4 after that I owned many a SAAB actually all SAABs up till I got my work truck which was a Ford..

Since then I have worked on all sorts of different makes, models and years..

I prefer European cars over american anyday.. For some reason I just don't understand why the american engineers do stuff a particular way..


So with that in mind I have talked to many a garage owner and mechanic.. You are either a domestic person or foreign..

The Japanese made cars I can take or leave.. They blend American engineering with European..

SAAB is or was still the best made cars in my mind.. Until GM ruined them..

Anyhow, The BMW Airhead Motorcycles are supposed to be robust and very reliable and long lived in stock form.. Like anything there are inherent weaknesses in all models..

I've talked with many BMW motorcycles owners who have 300K on their bikes with just annual service.. Plugs, wires, oil changes..

By the way. I've owned 5 SAABS that went to over 350K miles each.. My current Audi which I treat horribly has 310K and wouldn't hesitate to hop in it tomorrow and drive to California..

I thought BMW stood for Bikes Made Weird, or as they were called back in the 70s, Bavarian Murder Weapons.

The old BMWs are a lot more user friendly to work on compared to the new stuff. If you don't have a MoDeTec computer only available to dealers, you can't do much on one, even changing the brake fluid will disable the ABS unless you have the computer to reset it. Harleys are the same way too.

There are still some part available from a place in the Nederlands who bought out the remaining stock..

No valve covers or rocker arms or tappets..

Ideally I don't want to ruin the parts because of the rarity..

Someone mentioned going up to a 16mm shaft vs the stock 15.5 which BMW used and I am considering making my own rocker arms of which I am not excited to do.

Your freind must have been a fan of american made cars..

Not particularly He kept the BMW far longer than I would have.
It may have been a lemon but it spent a lot of time in the shop
When he replaced it he got a Porche.
I am glad there are at least some parts available
Good luck with this project.

Sometime you just end up with a lemon... sometimes another persons lemon is really a gem.. I guess it's all how the person looks at it..

My 2000 Audi with 310k on it I bought for 900.00 cash.. spent some money on a factory repair manual, learned how to do a timing belt on and audi and the rest is history.. Of course in my quest to go faster I did put a 6 speed tranny in it with 4:10 gears and a slightly larger turbo.. but since then it's needed 4 wheel bearings and an altenator and 4 steering wish bones.. I put zerk fittings on the wish bones so they last a lot longer now but the only thing that left me stranded with the altenator because I treated it like a SAAB.. The gen light comes on in the saab and you just rev the heck out of it and your good for another 500 miles..

I don't recognize the engine that the parts shown are from but it doesn't really matter. If you are deadset on Titanium in a sliding application then what you want to do is have it anodized. The porous surface will hold oil and be harder than the metal beneath.
The crap about Beryllium copper is just that, crap, To say that the chips are poisonous is ridiculous. Why would small pieces be poisonous buy large ones not so? The problem with beryllium arises from it's use in nuclear weapons where it is used as a ceramic, beryllium oxide. The ceramic can only be machined by grinding and the dust produced caused a lung disease, berylliosis, much like silica causes silicosis and asbestos causes asbestosis. The alloyed metal is harmless.
At any rate anodized Ti should do what you need to do.
