Question about Suzuki LS 650 Savage Motorcycles
I was driving and the bike began to spudder then shut off completely when i got it home i could start it but when i drove it down the road it did the same thing so i brought it back and i could make the bike idle but i cant give it fuel to keep it going i tried putting gas cleaner in the fuel didnt do anything plz help
Is difficult to diagnose these problems as it could be any of these;
Electrical; 90% of problems are electrical, in this case the spark could be breaking down under load and especially if the spark plug is old it may pay to try this first, Don't think there are any computers onboard the Savage but there may be an ignition system fault but this will be your last resort.
Fuel supply; cleaner additives are rarely effective and if there is contamination it will require the tank and fuel system cleaned, removing the carby fuel bowl for inspection for contaminants is the first step here.
Air Supply; Before doing anything else check for obstructions in the air intake, usually under the seat, this is especially important if you have fitted any seat cover, the webbing holding these on can be sucked into the air intake when applying throttle

i'd say the carb is gummed up especially the pilot jet (#16158) in this pic of the USA carb. may have to remove the carb & bowl and then remove the pilot jet (w/ flat head screw driver) and clean out the tiny holes.
the carb slide is installed backwards (turned 180 degrees). its #16025 in the pic. i've done this before on my daughter's XR70 and Z50. you'll know if its this when you move the choke lever, RPMs increase and decrease.
hope this worked for you and was fast enough.

take some wd 40 & spray around the carb boot while running to see if the idle drops for a few seconds. sounds like you have an intake side air leak causing a lean condition making the motor rev high.

ALWAYS have a fire extinguisher at hand when working on carburetors.
Drain the carburetors. There should be a screw on the lower side of each carb float bowl. Remove the screw then replace it after the fuel drains. 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). Turn the gas back on and wait a minute for the carbs to fill with gas. If the bike doesn't start and run properly then shut off the gas and remove the carburetors from the engine.
FOR EACH carb > 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. Remove the idle screw and the air screw on the outside throat of the carb and spray into the screw holes as well.
< < READ CLOSELY > >
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Before putting the slides back in the throat of the carbs, Move the clip on the jet needle one notch lower. Put the rest of the carb back together and install the carbs. Sync the carbs such that the slides on both carbs move at the same exact instant when the throttle is slowly turned from idle speed. This process should get you back on the road.
Please rate this solution. Thanks!
