The rebuilt NGINE worked great as you said. The line could have an air gap and need flushing. Check the plug and see if it has deposits or oil on the contact. Clean and gap properly. Check the electrical system to see if your getting a spark.

SOURCE: aprilia rs 125 starting problem

First check the battery to see its still fully charged. If it is do a voltage drop test between the battery and the starter to check for a bad relay or open circuit. If that checks out, you very likely have a bad starter/solenoid. I can explain how to do these tests if u need me to

SOURCE: vespa et4 125 cuts out after starting and riding for a few yards

before buying a new HT coil (as these are generally bullet proof on an et), remove the inspection panel and disconnect the spark cap. secure something long, thin and metal into the cap ( screw, tweezers, etc) and position it with a slight gap to the frame. disable the immobiliser and use the kick start. you should see the spark jumping from the metal to the metal frame. I fyou see this spark, it is most likely that the HT coil is fine.

Sometimes the diaphragm in the fuel tap can go wonky on an ET also, meaning that it might start alright but after going for a while, once the carb drains, the engine will die from fuel starvation. to test the fuel tap, remove the 2 tubes that run from the fuel tap to the carb at the carb end and **** lightly on the thin one. you will feel the daphragm open and fuel will run from the fatter tube if it is working.

Another thing that might happen if it is running for a while then dies is that the carb might be allowing too much fuel to the engine and flooding it. If when it restarts, there is a lot of smoke from the exhaust it could indicate this. leave it tick over for a while to run off the worst of it then increase the throttle slowly until you hit full throttle, leave it run back down to idle and you should be set to go. only use the throttle lightly and go slowly and it should bring you home at least then adjust your carb.

With apprila Rs 125cc 2 strokes bike. I fill up with 98 octane unleaded and I poured 2 strokes oil Into petrol tank. is it possible can damage the engine?. at the moment I couldnt start the engine.


well you cant damage it by doing that but if you put too much n and didnt shake it well it will settle at the bottom of the fuel tank and fill the carburettor up with oil as oil is heavier than petrol.why are you not using the oil tank and oil pump fitted to the bike ?best thing to do is put a new spark plug in it turn the fuel tap off roci the bike bacwards and firwards to mix the oil and fuel in the tank,and drain the carburettor by undoing the 14mm nut in the centre of the bottom of the carb,then turn the fuel back on and try and start it up.

Aprilla rs 125 1998 will only start when i put petrol where sparkplug sits


Hi, Angiep10 and the usual suspects are:
1. Fuel tank empty.
2. Fuel supply valve/petcock turned off.
3. Fouled spark plugs.
4. Engine flooded as a result of overuse of the enricher.
5. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
6. Fuel valve/petcock or filter clogged.
7. Discharged battery, check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
8. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and module.
9. Spark plug cables in bad condition and shorting, cable connections loose, or connected to the wrong cylinders.
10. Ignition timing incorrect due to a faulty ignition coil, ignition module or sensors (MAP, CMP, CKP, O2 and/or BAS).
11. Security alarm needs a reset.

Cant get aprilia rs 125 started


You need to box that thing up and ship it to me immediately. I will get to it and back in your hands no latter then say......2012...2013 at the latest.

Fine.
Pull your plug after you try to start it. What does it look like? If it's wet your problem is flooding, electrical or bad fuel. If it's dry your not getting fuel.
After you check the plug please repost here with what you find and I can help you out with a more specific cause.

I need to get to carbaretta to clean but cant lift petrol tank due to petrol pipe connected. how do i turn off petrol


there is no valve to turn off on modern bikes. you will have to syphon off petrol into a safe container and can pinch hose with a small pair of mole grips or bend hose back 180 degrees and put a rubber band on

DT 125 2000 Very poor starter. Stolen recovered so no ignition


had exactly the same prob with my dt 125.

In the fuel tank there were two filters that had become a little blocked with small fragments. I replaced both of these, aswell as the petrol tank and now works perfectly.Worth replacing with every service.

Also make sure the amount of fuel to oil is correct because if there is too much oil it leaves a small layer of oil on the spark plug which gets thicker when the engine cools. When you dip the spark plug in petrol and put it back in it obviosly makes a large enough spark to remove the oil, but repeats itself when the bike cools.

Hope this helps

Bke wont start


Hi there, try this sometimes the stand switch can make the bike not work if has got rusted at the back.and check or replace the coil., then check if you are getting a spark from the plug by putting the spark plug on top of the head. The next thing is if the bike turns over but not fire up, you need to strip down carb and clean jets, also check petrol value under the tank If you have a book it will go through this step by step. good luck.

Kawasaki kmx 125 2002 wont start


To me I want to know how old that gas is. If it smells like old paint or stale at all you need to rid the complete system. Then you need to take your carb. off and take it apart and clean it and all the jets, since you said there was sand in the gas tank.
