Removing "California" components from 87 GL1200 interstate

Post by lcdrjoe »



I started up the 87 project GL1200 interstate today for the first time since about 2016. I bought it cheap, but it's been sitting outside all that time. I got it with a seized engine, full of rust in the cylinders, but finally got her freed up, turning over, spark, removed/cleaned the carbs (that were also full of rust and varnish), fired up. However, while working on those carbs I discovered that they were 'California' carbs. My intention is to remove all that junk (purge control valve and associated vacuum hoses under the carb), cap off the associated ports on each carb, follow the vacuum line toward the back of the bike to wherever/whatever it goes to and pull it out and cap off whatever is needed. Then probably throw all that junk overboard. My question to you guys is: Is there anything I should be worried about? I've read a few posts on the subject and it seems that is all that is required.
I hit a bit of a snag on my resurrection of this bike. The carb rebuild kits all got delivered to somewhere in Mississippi, when I live in Alabama. I had to just clean what was there in my ultrasonic cleaner and put some parts from where I'd rebuilt the carbs on an 83 Sabre for those that were too far gone. The new slider diaphragms are somewhere in China, but 'on the way'. I made a couple temporary diaphragms using a rubber glove I cut to fit. I've yet to look in the gas tank, but I'm figuring I'll need to remove it and clean it out. Thanks for all the advice.
I forgot a question. On the slider diaphragms there's a locating ring that projects out from the outer edge of the rubber and must lay in a corresponding hole in the carb body. I've cleaned that hole thoroughly, looked at it using a magnifying glass and can't find an actual hole that leads to anywhere. On the carb body itself it looks like there might be an opening, but I sure can't find one. Does anyone know if that is just to orient the slider so the actual opening on the bottom of the slider faces the proper direction? It sure does to me. I kinda need to know so when I put new diaphragms on I get that orientation correct. Thanks again.

8.13.22 You are correct the protruding tab on the diaphragm, Orient’s the cylindrical carb slide, in the carb body. Did you ever get your bike to run correctly?

It's running, but still making a clicking/tapping sound on the right head. I just work on it when I have time. Probably going to remove that head and look it over again, or at least remove the cam cover and whatever so I can see what's in there that could be ticking.

Again...
If you look on page 7-23 of the '84 ~ '87 manual it shows how to center the cam. It refers to earlier models but the noise is present in several '86 & '87 models as well. Took 10 minutes (not including removal & replacement of the valve cover) to fix it on mine and the noise hasn't come back in over 200,000 miles.
