cleaned my carbs now what

[James (Jim) W. Jackson]

I have a 1979 GS1000. I've adjusted the valves, replaced the plugs, points, and condensers, and timed it. I purchased carb kits from Z1 and was planning on installing them. Last week the bike was running poorly and starting hard, so I figured that it was time to clean the carbs. The carbs were disassembled, dipped, scrubbed, blown, rubbed, reassembled and installed back on the bike. I set the pilot air screw (top) at 1 1/4 turns out and the pilot jet (bottom) 1 turn out. The bike started and ran...poorly but it ran. It pops, backfires, farts and generally runs like crap. What now? How do I proceed from here? You help would be appreciated......

Just curious, what are you using for an intake system?

Open your air screws another turn

Stock? Pods? 4-1? It all makes a difference

Hi Mr. Jackson,

It seems you have two similar threads going concerning the same issue. So I will post here also. Welcome to the forum.

If you did not follow THIS PROCEDURE, soaking each carb body in Berryman's Carb Cleaner for 24 hours, and install THIS O-RING KIT, I would suspect that you still have carb issues. There is usually no need to install aftermarket carb kits. Just clean the carbs properly, install the new O-ring kit, and reassemble with the stock hardware (unless it is damaged or worn, of course).

There are a couple of maintenance lists in your "mega-welcome" that will usher you into GS-topia if you follow the prescribed procedures. Let's get started.

I'm glad you found us. I just stopped by to welcome you to the forum in my own, special way.

Thanks for all great information and welcome. I did disassemble and dip the carb and parts. I am running a stock air filter and box. I just could not find any information on what procedure one uses once you put it all back together and it still needs tweaking.

There's a tool you can buy called a Morgan Color Tune that's basically a see-thru spark plug that allows you to see the color of the spark inside the cylinder. This helps you set the air mixture screw at the perfect setting. Here's a link of how to use it:

It's a little pricey, which is why I haven't bought one. But, if you don't trust your own ear, it's a good way to go.​

I didnt see anything about adjusting the valves in your OP... When is the last time you did this? Hard starting is a classic symptom of valves that are too tight. The valves dont seat and seal all the way, the compression is not what it should be, and the bike doesnt want to start..

Perhaps a little background on the bike? Have you ever known it to run good or did you just buy it in its current running condition?

I'd look at intake O-rings, carb O-rings, air box sealed?
Speaking of compression how is it?

Keep us posted!

Hi,

Most will "bench sync" the carbs before putting them back on the bike. Then you fine tune with a vacuum sync procedure. Properly adjusted valves are very important and should be done before vacuum syncing the carbs.
