Re: went to reserve fuel - then motor backfiring and loss...
Condensation in the gas tank collects at the fuel petcock. Get enough water in there and it gets into the carbs. ALWAYS have a fire extinguisher on hand when working on carburetors. Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ). Drain the carburetors. There should be a screw on the lower side or bottom of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.
Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Put the carb back together and install the carb. Let the float bowl fill then start the engine. This process should get you back on the road.

If the bike was working normal and do not have more then 50-60 Tmiles, then the chains are o.k., this bikes have a automatic chain tensioner, so, you can start to think about change a chains when you are over 50000 miles. Usually, when chains are on limit, you can hear a rattling sound on the top of cylinders.
Backfires usually comes from bad carb sync and if you put custom pipes also to small jets. But first try to sync the carbs.
Here is link to youtube it is for vt600, it is the same for vt1100:
Sounds like something has clogged one of the pilot jets in the carburators. You can figure out which one by feeling which pipe is cold after running for a short time. Probably best to clean all 3 carbs while you have them off.
Honda motorcycle suffers from sticky valve stems. this causes the intake valve to still be closing when combustion occurs - and a second explosion occurs in the manifold - which you hear as a back-fire. 2 oz Mega Power Gas Treatment #93 in the fuel and 6 oz Mega Power Engine Tune Up in the oil and a couple 500 mile oil filter changes- each with 6 oz Mega Power Engine Tune Up in the new oi. I run both all the time to keep the problem away. Get the products for your cars and your bike. Source: http://www.auto-tune-up-and-repair-options.com/worn-motor-treatment.html
I do not agree your bike should run better then it sounds like it is. Just throwing on a set of pipes and a carb kit is not always all that needs done. I ask about the air filter because it seems your motor is getting to much gas and not enough air. The thing I would do next is to get a higher flow of air on the intake side by going to a high flow air filter. A quick check to see if this will help is to temporarily remove the air filter and test ride the bike. If it runs better without the filter this tells you a high flow filter will help. Your bike may need more work than this to get it right on. The other thing you could have done is get someone to jet in the carb to cut down the fuel flow and get the fuel air ratio right on.
I need more information. Is the bike carburated or fuel injected? Did it just start this or has it been doing this for a while? It sounds like either an ignition or a fuel problem.
If it has a carb, I'd say that it's jetted way too rich or the main jet has come loose in the carb maybe. Tell me what kind of carb is on the bike if it is indeed carburated. I need the year model of the bike and the name of the carb on it. Maybe I can tell you how it's supposed to be jetted. If the main jet has come loose, you will lose control of the amount of fuel going into the engine at wide open throttle.
You may have a bad spark plug as well, either get a new set or have the ones you're running now cleaned. When you pull them out, look and see if they're really black and sooty looking. This is indicating a rich mixture. Check your spark plug wires and make sure they're in the coil correctly. Check of loose connections at the coil primary (small wire connections) connectors. Make sure that chrome cover over the coil is not loose shorting out the ignition.
Fuel injected, I can't help you with that as it takes a special device to make any adjustment in that system.
