Standard jetting depends on vin. Also I have been told pod setting can be very different up to 11787 11788 to 19375 19376 to 20656 20657 on main .......................105..................................97.5................................100................................100 air.............................1.1....................................0.7....................................0.7...............................0.7 pilot..........................22.5..............................27.5.....................................15..................................15 .mix screw set out.....1.25.........................1.75.....................................1.75..................................1 What kind of exhaust? I have a V and H and they want 115 main 17.5 pilot and you may need to raise the needle 1 notch. Thats all I can help ,with and to say, I have read that these bikes hate air pods and are much happier with the standard air box. Be careful not to block th slit on the top of the carb intake with the pod

Thank you all, for all the shared knowledge. Im not able to do any more till Sunday. I have also decided to take off the inline fuel filter I installed, cos I believe it is too fine and starving the 4 cylinder a little. I will post all findings and check for the metal loop on the back of the airbox, fit and route tubes, and block unused vacuum spouts. Thank you again.

Thank you. So what gets blocked off securly?

Thank you I took your advice and removed the " loop tube" 'c' in the pic. All 4 cylinders are now firing. Any ideas how I plug the other 2? Nearly time to go for a run. I have owned this bike for three years and never ridden it. I installed Dynatek coils, and ignition update with new leads, new chain, and sprockets, the exhausts were rotten, and I needed a new headlamp, ( USA import ).The rear tyre was stamped, 1986, so a new set was added. 100 and one other things too with a new battery last week. 23,000 miles, 78, and original paint.

Inlet side? Yeah sussed the pics upload- This all looks good.Did the 1st pic help? Should I try the small pipe from the tank on an other carb? Do I block off the others spouts on the carbs if there is no pipe on them?

How do you post pics please?

Hi. Thanks in advance. I have had a GS750 in the shed for some time. I'm getting close to riding, only today, when I fired her up, she wont fire on cylinder3...unless I take off the small vacuum hose ( I think its called) from the back of the tap for the tank. When I do it wont fire on 4 and will fire on 3? Ive got the hose ( A) running into the right side of carb 2. Is that right? I also have a loop of hose same dimension, going from right side of 1 to right side of 3 ( c). Is that right? A = the hose from ( vacuum ?? ) tank to carb 2B= Main tank hose to railC= loop between 1 and 3D= engine breather to airboxE= clutch cable
