I have a suzuki 125 ts was riding it then stop for

Check the cylinder with a compression gauge

Hi, the standar for the air/gas screw is 1 & 1/2 turn out from total screw in. Start from there and then you only need minor adjustments. As for the 5 min ride and then nothing, check you fuel suply, start with the buoy level inside the carb.
good luck

common thing with 2 strokes is that if the plug isnt in good condition they wont run

i run a ts 250 2 stroke and i have to change to plug a lot more then a 4 stroke

If your confident of a good spark, then your issue is fuel delivery. Try raising the slide needle by going down one notch on the needle. Jets and needle seats should be cleaned in a good quality carburettor cleaning solvent. Jets should be replaced if suspect. Check condition of reeds. Is the airbox and filter in good condition. Check for leaks around inlet manifold. Goodluck, cheers!

check to see if gas is flowing from gas line make sure fuel tap is turned on. Check the plug and replace it if not new check to see if the carburetor is dirty. Make sure if you have an oil injector to check the oil lines. To name a few things.

Check for spark, compression, replace plug.

Clean your carb and replace your spark plug that should fix the problem.

coil or cdi

best spark plug is iridium plug, takes the heat and lasts alot more rides. could be flooded, take plug out , stick finger over hole , kick start till it drys out. take match stick and clean inside of plug, should be good. otherwise probably a fuel problem.
