Re: Forum upgrades to handle R90S World
James, thanks for all your hard work.
And folks, James and I have discussed what he is doing and what communication form to?use for communication at the Vintage BMW Motorcycle Owners, IOW the regular?forum format of the VBMWMO, or emails as the R90sWorldnet has always had. He has implemented as far as possible, the email way of communication, as well as the forum format, so there are?options, as I understand it. He has done the very best he can do, considering what?is available technically.?
Thanks again James.

Better email support for the forum
All R90 Worldnet members, I have heard from several of you that you wanted better email integration for the forum to make it more like the groups.io email you are used to on the Worldnet. The good news is that I am working on it and I will have something better in the coming weeks, but it will be incremental and I rely on your feedback to tell me how good it is for you and what you might like to see.? The bad news is that the functionality is not going to go from your "typical forums" to perfect in one shot, it will be slow and will likely never be able to fully replicate the email system. ?I will work on it though as it will make the forum experience better for everyone. Please email me at webmaster@... with any questions or comments! Thank you!! James

THANK YOU JAMES WONDER!! Migration to forums is done
We all owe a big Thank You to James Wonder for his wizardry and big time efforts in successfully moving the R90sWorldnet with io over to the Vintage BMW Motorcycle Owners website now titled ¡°R90S World¡±.?
We can all access the new ¡°R90S World¡± at the Vintage BMW Motorcycle Owners website under Forums.? See below.?
On behalf of all R90S owners and aficionados,?

Now More: Migration is starting to the forums! + Now More
See below from James Wonder.
Here is more: I thought of using the R90sWorldnet name at the VBMWMO website instead of ¡°The Incomparable R90S¡± but James suggested the name ¡°R90S World¡±, which is great and pays homage to the the R90sWorldnet.? So look for that name shortly.?
And the VBMWMO website needs technical upgrades for added security, and due to advancing technology.?
SO the VBMWMO club is paying for a big website upgrade which will have wonderful advantages, including making James Wonder¡¯s job much easier.?
Thanks,
Mac Kirkpatrick

I had two of Chuck's units at my shop. They were especially good for the annoying-to- sync dual-plugged Airheads, not just the stock plugs Airheads. NOTE that these meters are used with a snubber at each meter input....a snubber slows down the air volume movement speed, which is much easier on the very sensitive meter...and...makes it much easier to read the otherwise jerky meter. The snubber was made in two types, both of which work about the same: Scintered (porous) material that slowed the air movement, and the other type had a very tiny hole that did the same thing. No battery or electronics was needed. For years, these units Chuck put together were the best thing available for the purpose. I still consider them really good, top-notch, and very particularly good for synching the engines with two plugs per cylinder, since no plug shorting was needed. Walus Engineering did all sorts of machining work, especially dual plugging and a battery size conversion. Snowbum (AKA Robert Fleischer) Learn from the mistakes of others, because you cannot live long enough to make them all yourself! A large number of good tests, inspections, measurements and both good and bad experiences, are more valuable than many opinions, particularly if found in a Facebook Group.

Picture of Dwyer Magnahelic
Somehow picture got omitted from first email. Here it is.
|
?
This is my go to gauge. I¡¯ve had it for at least 40 years, but just had it rebuilt. It was put out by Chuck Wallus who use to make all sorts of BMW service tools.
It is actually a Dwyer 15¡±-0¡±-15¡± Magnehelic.
The action is very smooth and precise. Very satisfying to use. This type of gauge is often used in precision laboratory measurements and widely in the HVAC trades.
Dead simple and accurate. The last carb balance tool you will need.
Cylinder shorting is harder for me on both my twin plugged R90S and R100RT.

IMO, adjusting the carbs and throttle cables is most accurately done by the shorting method.? The other methods are various ways of measuring or comparing, the signal at the vacuum takeoff ports; and, one method of measuring the incoming air flow to the carburetors.? Most folks have a favorite method.
I like the shorting method, as it costs little to nothing, and is very accurate.?? That method¡.AND OTHERS¡.are fully discussed, here:
?
The method I most dislike hearing about is adapted from the method BMW promoted for the PRE-/5 models¡.well, perhaps better said, the magneto models¡in which the spark plug caps are removed and re-connected, back and forth.? It's not at all safe for the later models (/5 onwards) that have coils, but no safety gaps¡.and, is not all that accurate, either.

All you have to do is with a tiny drill (like #57) poke through the last mm or so.
If you remove the pilot screw you can see daylight right through.
The port is 6mm for the hose but steps up to 7mm for the press fit into the hole.
Some locktite will probably help.
