Check the ignition relay, because it may have overheated and gone faulty. If you can hear it click when you press the ignition button but the starter doesn't operate then the relay could be faulty.

On the right side of the bike near the site glass for the oil level there may be a chrome cover you will need to remove. it should be somewhere near your right heel as you ride the bike. On the large round crank case cover. Some older bikes use the same cap to included the 'dip' stick.

Remove spark plug and put 1 tbl spoon of gas into cylinder and replace plug - if it starts and runs for a couple of seconds you have a fuel delivery problem. Remove and clean carburetor.

A lot of times the cards rarely get cleaned even if it seems cleaned....I always take carb cleaner to each jet then just to make sure shoot air through the jets an around outside and inside carb or carbs.....if that didn't help then maybe the air and fuel adjust screws vibrated loose...should be 2 screws either by the fuel line side of carb or on top .....if u don't know much about those tuning screws then I'd recommend taking to someone who dose otherwise you'll sell it be for it gets set right again

Check the feed wire that goes to the fuse block to see if it has power. There should be a main fuse somewhere close to the fuse box.

As it is a vx engine going into a vs frame Suzuki may have used a different wiring harness to allow for differences in engine layout and the electronics fitted.
Is the engine the same age as the frame it's going into? Age differences can also affect the wiring layout.
You will need a wiring diagram for your bike and a separate one for the replacement engine. You will need the layout of the engine sensors as well.

Could be a number of things. My first question is when was the last time it was serviced ? Second, ( this might be the obvious ) are you down shifting to a low enough gear ? Is this the only symptom that you are experiencing, or does it back fire or hard to start ? First things I would investigate : 1. Air Filter. 2. Bad Gas / dirty Carb. . 3. Spark plug 4. intake gasket. 5. Charging system. (i.e. Stator, rectifier / Battery). If none of these help, it may be a more serious issue.
