You can try to do this but the Shadow VT 1100 has been known as a bike that is not so easy to tune. Some of these bikes have had carburetor jets replacement, increasing the power of the engine, as well as other modifications to air intake and exhaust pipes. If this is the case, then it may complicate the matter. If your bike is a standard issue without modification, you can try the following.
First, you should synchronize the carburetors. There are screws on the throttle linkages that are used to adjust this. Carburetor one is the "master" and carburetor two should be adjusted so it works exactly like the first one. Run the engine at 1100-1200 RP-M's and then synchronize the other one to that. You have to use a manometer or a vacuum gauge set to do this, something that the general motorcycle owner does not own.
To set the air to gasoline mixture, the default setting or starting point of the idle screws is 2 1/2 turns each.

How do you adjust the idle on a 1986 Honda Magna?
Sorry for my English I will do my best to explain this. The carbs of this Honda Magna have a knob in the middle of the carbs. It is for idle adjust, but is the problem is bigger you have to clean the carbs, check the jets and diaphragms is better if you can use an air compressor or maybe a vacuum sincronizer.

What is the Top speed of a Honda shadow spirit?
I have a 2006 shadow spirit 1100. I read that you can expect 70-98mph tops, but this weekend I rode it at 110-115mph on the highway...I have hard chrome pipes and the carbs were jetted to match.....that's all I've done to it except to put a windshield on it.

86 Honda shadow will fire but won't stay running when it does it idols rough and backfires a lot removed the carbs and cleaned them but still have the problem any ideas about how to get it to run?
your plugs may be fouled. pull them and check for carbon buid-up, discoloration, etc. you may be able to clean them and adjust the gap. also, very much sounds like a timing problem. the timing could be off just enough to permit the bike to start but will not accept throttle, idles rough, & small back-fires through the carbs. hope this helps
Where is the idle adjust screw on cb250?
Underneath the carbs, near the throttle on the right side of the engine.
