You sir, are the Bob Ross of Airhead instruction videos. Incredibly thorough and calming, you help me approach a procedure confidently and well informed.
Wally, Thank you for your kind words. I hope the videos and the links in the video summaries to my website's detailed information about each bit of work will help you keep your airhead running for years to come.
@@BrooksAirheadGarage Everything went as planned until I tried starting the bike... Starter is cooked....oh the joys of owning a 79’ R100RS... have you refurbished a starter before? Any suggestions?
@@chrisfitchett7645 I did rebuild a Bosch starter and you can see the details here: --> brook.reams.me/bmw-motorcycle-rebuilds/1977-bmw-r100rs-rebuild-project-index/12-bmw-r100rs-refurbish-starter-motor/ You can get all the parts at Euro MotoElectrics (www.euromotoelectrics.com). They also sell a replacement Valeo starter motor that is a very good value and highly recommended if you want to replace yours rather than rebuild it.
Thanks, Brook! Lots of useful information here as I have exactly the same type of bike, a 1983 R100 RS. And this winter I'm going to change the fuel line that goes under the air box, as it's pretty rotten. Never been changed. Luckily I have the European version of the RS, and not the US version, so the extra tubing is not there. Simplifies things. Thanks again!🙂
Very clear Brook. I’m just a couple of months ahead of you but will check my cable routing after looking at yours. Had same fiddle with cable junction box. Luckily no emission stuff on Euro bike airboxes.

Brook, I have a 1991 R100GSPD and have researched, ad nauseam, recipes for an engine upgrade. Yours is the only source with enough detail that I would feel comfortable enough to follow. What were the noticeable or measurable gains and were they, in your opinion “good value?” What, if any, changes would you make to your recipe? Thank you for your contributions.
Did you replace the diaphragms? I remember people wondering why their bike was running poorly and a lot of the time it was a hole in the diaphragm. My /6 I put 114,000 mi. on it and I replaced the diaphragms on one of my winter maintenance times some were around 50,000 mi. Thanks for the nice video, I always learn something!!
@@BrooksAirheadGarage Brook: I hope you don't mind but I do have a couple of questions: 1) it appears that the tire sizes on the R100RS are the same as on my nice old Yamaha XS650s: (3:25-19 front and 4:00-18 rear) - but most guys are using modern metric sizes which are: 100/90-19 front and 120/90-18 rear. Do you have any experience using those metric sizes on your bikes? The selection of brands is much wider for the metric sizes and some day it would be handy to know (I have been using Michelin Pilot Activs on the Yamahas). 2) do you know of a good source for decals for the R100RS? In my experience, these are often deteriorated on older bikes and I am sure that somebody, somewhere has reproduced them - but who? Cheers, Peter
@@assessor1276 1) I have been using inch size tires, so I have no experience with metric "almost" sizes.

What a quality video, very helpful. Thank you so much for posting this. I see lots of videos from others that are helpful but your detail is what makes these so good. Do you have a video on setting float heights. I have read they can become heavier over time and as mine are probably original I will replace them over winter. I have an 1981 R65LS which is frisky in all gears but in top it bogs down at 65 to 70mph I have read float height and weight are the first things to check. I am off to watch more of your videos. 👍👏👍👏
Ninja Badger, I too suspect your floats are sinking. New ones make sense. This article by Bob Fleischer (aka Snowbum) has all the information about the two methods of setting the float height: (1) checking when fuel flows through the float needle, (2) setting float height based on fuel height in float bowl. --> bmwmotorcycletech.info/bingcv-2.htm
@@BrooksAirheadGarage Thanks very much for your reply. It must have been some of this info I had read on forum's which people had quoted. Your videos are so addictive. 👍
Hey Brook I have a question? I have a 78 Airhead! Looking at the air filter cover there is a hole at the top. On some earlier bikes I have seen wire coming out of that whole. What is that hole for?
Hi Jupiter, If I recall, the '78 used the earlier "clam shell" covers and a cylindrical air cleaner. My clam shell covers on the 1973 R75/5 and 1975 R75/6 didn't have any hole in the top of the clam shells.
Hi Brook! A boatload of mice ate and defecated in the airbox of my bike so I did my very best to clean it up. That being said the "pumps" for the pulse air system are pretty much trashed. I could potentially get rid of them as well. Can you explain why you decided to get rid of yours?
Quinn, Yes, I removed the pulse air system as it overheats the exhaust valves which already run too hot if the original valve seats are still installed. I show how I did that work on my web site in this document: brook.reams.me/bmw-motorcycle-rebuilds/1983-bmw-r100rs-rebuild-project-index/13-bmw-1983-r100rs-update-pulse-air-system/

Hi Matt. TIP: Patience is a virtue. :-) The video shows how I did it. I installed the handlebar cable first then the left and right carburetor cables. It was a tight fit when installing the carburetor cables. I mention that I had to cock the plug enough to get the ferrule on the carburetor cable into the slot in the plug. The original handlebar cable had a longer inner cable than my new replacement cable which lead to the difficulty installing the carburetor cables.
