Referring to my introduction post I have some questions I am sure you guys can help with.
After Dai asked if I replaced the rubbers around the throttle bodies I took a really good look and I do have some minor cracking and they are as hard as cement. So I will be replacing those. My questions are.

1. Where can I find proper replacements?
2. Do I need to try and save the original clamp or do I buy replacement clamps of the same type or a hose clamp?
3. When I am digging that far down into the bike, is there anything else I should be paying particular attention to?

The bike has 126K miles and despite some legality issues I am going to have to take it for a spin and try to sort out if things are operating properly. I've sorted out most of the electronics and flushed brakes and lubed the splines. All fluids are good and I redid the fuel system. I will be purchasing both a Haynes and Clymer as was recommended but I admit, I do not know what all I should be looking for. The tires are new as well.

Any help or advise would be appreciated. Thanks in advance.

Items FUA60408 and FUA61739. I bought FUA60408 as a Used part with no problems, but I wouldn't trust the throttle body rubber sleeve secondhand. Fit the intake stub with a smear of Threebond or similar underneath it.

As regards the hose clamps; you can use good old worm drives. It's possible to get the narrow body ones that will fit the existing depressions (I think it was RickG that sourced those?). The worm drive itself will need to face the inside of the engine but you need to be extremely careful not to foul the throttle quadrant, otherwise you risk the engine screaming its nuts off.

Anything else? As suggested, check the vacuum caps (FUA60594) and the vacuum pipe on no4. throttle body. And this fella: ENA6048. I'd get a couple of those as they have a nasty habit of rupturing and completely upsetting the running of the engine.

I have a question about Clymer Manuals? I've been looking on Ebay since as usual I am on a tight budget and have noticed differences in the manuals. I have seen 3 differnat covers on manuals and I am not sure if it matters which one I get or  am I just being a paranoid noob.

1st Manual: K75 - K100, 1985 to 1989
2nd Manual: K Series, !985 to 1997
3rd Manual: K Series 1985 to 1995

Does it matter or am I being paranoid?

Thoughts?

They all cover your bike, if you're on a budget go for the cheapest that is in good condition.

If your bike is an '88 and the first manual covers off to '89 then there may not be any extra info/modifications that are added in later additions.  I have seen this in my two Haynes manuals.  For example ABS.  

If you end up with a serious case of K pox, then this may become relevant.  

I have an 88 k100rs and had no problem getting the information I needed out of the clymer manual I bought for 40 bucks on ebay.Mine was left sitting for close to 15 years in a basement with ethanol laced gasoline in the tank and everything in there turned to this rusted up mess.Long story short,it all got fixed by me and is in service .I'm riding it up to the Adirondacks Saturday for a two week ride in the mountains. I'm sure your bike will be the same. They are great bikes  , good luck and remember that there are some good parts vendors like this guy where you can get parts for half what BMW charges,https://www.euromotoelectrics.com/

If you're on a tight budget, Martin is recommending the best approach. If you start trying to collect K-bikes—as Tackler suggests is a possible outcome—making timely mortgage payments or eating regularly then would become your largest concerns.

Clymer is an excellent source of information, but you also can find cost-free [url=http://service.tanga-moteurs.ro/data/BMW__k100 %26 k75 Haynes Manual.pdf]the Haynes manual online[/url] and the BMW workshop manual in the Portal here. Consulting more than one manual often helps to clarifiy procedures, as Dai frequently points out here.

Thanks for all the input guys. I do appreciate it. This will be my 1 BMW for this lifetime. 
I already have the Haynes and BMW online manuals Laitch, but thanks for the links.
I like to have at least 1 paper copy to sit down and read while doing stuff although my laptop will be right beside it. 

I did the same thing to my RS as you are now. Check out my post on Throttle Bodies a bit further down on this forum. I got the air box to throttle bodies boots from AS BMW motorcycle parts and I think MAX BMW motorcycles has them too. And they have the hose clamps too. I also replaced my fuel injectors that made a huge difference!
