Marauder 125.engine will only start on choke even when bike is warm. its doe 3000 miles and is 1998 model.

carb needs cleanin or overhaul--choke is dirty and jets also--howevr they mite just need ajustn-but let a pro doit cause engine damage cud occur

Is it normal that a new bike dies on you as you drive it? No way my friend. The carburetor should have a thermal-choke and it probably needs some adjustment.

This is fairly normal for the model Suzuki you have. Because of the manual choke, of course you have to do this by hand as you are doing. Newer models have automatic chokes.

first drain the carby, then set your air mixture screw 2 turns out, from the fully turned in position. The starting proceedure is as follows, when the engine is COLD, turn on fuel, pull on the choke fully, and kick the engine over. DO NOT use any throttle, when the engine is cold, and the choke is on. Remember Choke on, NO throttle.
When warm, no choke, and a little throttle when kicking.

You need at a minimum, a shop manual for your model. Check at http://www.suzukiownersclub.org/usa/ for a manual. Look in the tools section for guidance on what special tools you will need for this.

If your bike has ever been sitting for more than six months to a year, then the carburetor is likely clogged with fuel varnish and needs to be disassembled and cleaned. If the throttle response is improved when the choke is applied, then the carb is plugged for sure.
Sometimes, if you're lucky, you can simply drain the stale fuel from the float bowl and see an improvement. I would try this first, because it is possible that some moisture has collected in the carburetor float bowl and is causing the poor throttle response.

Is it fuel injected or carbureted? If the bike is fuel injected it will idle fast until the engine warms up...if it continues to idle fast after about 10-15 seconds it could have a faulty sensor.

If carbureted, after you push the choke in does it still idle fast? If so, there is an idle adjust screw on the top of the carburetor just behind the air cleaner.

Do you have a tach on the bike? If you do, then the normal warmed-up idle should be 1000rpm.

Take it to the dealer under warranty.

check battery for full charge and tight cables.use test light check for power to starter when pushing start button.if there is, check starter. if none check for power to start solenoid on small wire going to it w/ testlight when you press start.if none, check start button, & wiring.if youi have power to it,but no start, take large screwdriver & make contact between both solenoid cable posts,make sure bike is in neutral. should crank, confirming that solenoid is bad.also, even if the solenoid has no power going to it to energize it you can still use the screwdriver trick to get bike to crank.
