38mm Dellorto carbs.

I am getting conflicting information on the 40mm Bing carbs vs the 38mm Dellorto carbs as furnished on the R90S. Anybody know if the 38mm Dellorto's have as much performance capacity as the 40mm Bings? At first glance the smaller throat size in the 38mm Dellortos should have less capacity to flow ai...

Re: 1970's headlight & instrument cluster lighting upgrades

Srankin I am interested in the Katdash upgrades not necessarily the headlight bulb. My 79 year old eyes are not good enough for night outings anymore. What I want is the Katdash upgrades as well as upgraded or reproduction instrument housings for all 3 of my air heads (R90 S, R1000 R, R1000 RS.

Re: Brown side stand question

I have found when installing rubber parts (i.e. grips etc.), I use gasoline on the interior of the rubber part. The rubber parts slip right on and when the gas evaporates the rubber part adheres to the intended other part.

Re: New to this site

Have been putting some miles on the R90S and I have a problem I will have to address probably the end of this riding season. I want to send the instrument pod off to a specialist for as complete restoration as possible. I want to get the gauge glasses replaced as well as the gauges calibrated. The w...

Re: New to this site

the 83 R100RS I bought in New Hampshire is a beautiful bike. Very nice restoration that needs nothing. Same owner also has a 1977 R1000S I looked at when I picked up the RS. Have decided to buy that one as well. Buying three old air heads within 7 months and never having owned one may seem somewhat ...

Re: New to this site

Leave tomorrow morning to pick up my next airhead project, a 1983 R100RT. This one is at least all together and not like the mongrel built up out of parts from various year airheads. Over 1000 miles each way so I hope this one is everything the current owner claims. :D 8-)

1970's headlight & instrument cluster lighting upgrades

Having now completed the mechanical repairs and upgrades to my mid 70's R90 the next thing I want to upgrade is the headlight output as well as the instrument lighting. Everything is working but the headlight output is particularly weak by modern standards. Anyone who can steer me to better light ou...

Re: New to this site

Well the mongrel is finished except for replacement of some of the original frame stickers. This project came out really well and I love riding it. Being a sucker for pain I am now looking for a second airhead for restoration. :D 8-)

Re: New to this site

Tach problem fixed. Guenther took it apart and found several components on the board had failed. Cold here and the weather is to bad to ride so I am going to take the trailer to pick up my bike on Sunday. I had forgotten this but the R90S bikes that were raced in superbike in the 1970's were actuall...
