New guy question #1 carb vac slide sticking

Postby Bomber737 » Tue Sep 20, 2016 10:47 pm



Hi to all, new guy to the forum little background on my self. I usually purchase a couple of bikes every summer and spend the winter getting them back on the road by summer. If I like them I keep them and if not I sell them on. I have been doing this for the last 8 years and have the opportunity to ride a bunch of different bikes. My current bikes are a 1980 Suzuki gs1000, Yamaha radian, 07 Yamaha roadstar. This winters projects will be a 1971 BMW R75/5 and a 1978 Suzuki gs1000. I haven't owned a GL yet but well see how this goes and maby Ill go get my own. I have a friend who owns a 77 GL1000 and a GL1200, he loves his. I am currently working on a 82 GL1100 for a different friend. So far the bike seems to be in Ok shape. Some screws missing here and there, This bike does run and it does charge so at least we have that going for us. I am currently working on the carbs. He purchased it from some guy who said he had cleaned and rebuilt the carbs but there was green residue in the float bowls and the bike ran like crap. So I pulled them and took them apart. Everything was going great until I got the last carb #1 out of my ultrasonic cleaner and while re-assembling it found the vacuum slide sticks at the bottom of its travel. So I am in need of a suggestion as to how I fix this problem? I have already polished the carb barrel and the vac slide sides with 0000 steel wool and it polished up. Its better but is still sticking slightly. For some reason it feels tighter than any of the others. How do you guys fix this problem? Any suggestions would be great. Thanks in advance

Welcome to the forum.
Careful polishing would normally work on this problem, however, if the 1100 carbs are the same as the 1000, the actual needle should have some side to side 'slop' in it, to allow it to centre in the jet properly. If the needle is rigid, due to someone overtightening the large threaded retaining screw in the bottom of the tube above the needle, it may well bind, causing sticking. Check that the needle is able to wobble side to side (as I say, assuming that they are the same as the 1000). If not, back off the retaining grub screw above it. Also, check that the needle isn't bent.

The steel wool was not a good idea..better to use a scotch pad from the kitchen or jewelers cloth..but too late now good for next time..good advice above. Did you polish the tube and the shaft?
HAD LOTS OF GOLDWING 75-83

Thanks guys. Yes I did polish the vac slide as well as the carb body. It did shine up nicely and removed the scuff marks. The steel wool I used was the finest they make. Its like cotton ball consistency. I re-installed the caps in the orientation they came off and I did chech how well the vac slide moved in the cap. They all move freely and bounce the same amount. I did find what my problem was and I feel really stupid for not noticing. The brand new needle I installed in that carb was slightly bent so of course the vac slide would stick. I cleaned up the best of the old needles and it slides like butter. The carbs are back together now and I am off to Fastenal to find some new cotter pins. The old ones broke when I was reinstalling them of course.

I got the carbs back on the bike tomight and it actually started and ran quite nice. Will be syncing them tomorrow, then all I have to do is fix the brakes and clean out the master cylinder and my work is done. I can give it back to my friend and go find me a 75 to 77 for myself.

Carbs synced and the bike starts 1/2 second after you push the start button. While syncing I verified the readiator fan works. I did discover that the throttle cables are miss-routed so Ill have to address that and get the air filter re-installed. I think once thats done ill tackle the timing belts and find the missing screws on the front brake calipers. How someone looses those is beyond me.
