79 gs 750L carb problem

[olegrumpyman]

Just got a new to me gs 750 the guy before me messed with the carbs. I just put in new jets and pilots but all I can find for settings is that it was set at the factory and don't mess with it. Can someone give me a starting point to set these. I not sure what they are called but one is in the bowl ( pilot jet)and the other is on the top side at a angle ( air jet ? ) Thanks PS vm26ss are carb type

Hope you did more to clean the carbs than just replace a couple of jets. cycleorings.com sells kits and there is a tutorial for the rebuild in the Garage section - link though the GSR homepage. Also, don't forget to replace the intake boot O-rings if your bike has them.

Screw on the bottom is the pilot FUEL jet - good starting point is 3/4 turn from lightly seated. Screw on the side is the pilot AIR jet - 1.5 turns is a good start. Tweak as necessary and don't forget to do a vacuum sync.

I did what I could, cleaned and adjusted floats and bought a kit off ebay with everything but the long needle inside the slide. thanks for the help Im sure I will be asking for more in the future.

Greetings and Salutations!!

Hi Mr. olegrumpyman,

I'm glad you've found us. I encourage you NOT to take shortcuts when it comes to carb cleaning, electrical maintenance, valve adjustments, etc. Check the mega-welcome, particularly the "Top 10 Common Issues", the carb rebuild series (there is a VM carb series in the Garage Section of the GSR homepage and on my website), and the Stator Papers, to put your bike back into a condition where you can do more extensive troubleshooting if necessary. Don't forget about your chain and sprockets either. If you are not proactive with these issues, you will become frustrated from continually chasing down all the related problems. Ask me how I know.

There is a "sticky" thread at the top of this Tech section which contains most of the specs for the GS carburetors. The search function can find instant answers for you. Now, let me roll out the welcome mat...

Please click here for your mega-welcome, chock full of tips, suggestions, links to vendors, and other information. Then feel free to visit my little BikeCliff website where I've been collecting the wisdom of this generous community. And don't forget, we like pictures! Not you, your bike!


Good luck with your wrenching. Keep us informed.


Thank you for your indulgence,
