Sounds like when you hit the bump in the road, you have done something to the wiring of the Sym Jet 4. Could be an earth problem there Jamie so, carefully check all your connections right back to the fuse box. and also check your fuses you might have blown one with the Impact.
Ok hope that helps start you off Jamie.

Can I lower the ride hight of my Sym Jet 4 125 as I find it hard to put my feet down


Hi, Terry here are some options for lowering your bike depending on your needs and how much "DRACHMA" you have in your wallet:
1. Rear shock lowering kit.
2. Front fork lowering kit.
3. Shorter rear shocks.
4. Shorter front forks.
5. Thinner padded seat.
6. Lower profile tires.
Please be aware that some of these options or a combination of options will require a shorter kickstand or your stock one modified. For more information about your issue and valuable "FREE" stuff that you will need please click on the blue links below. Good luck and have a wonderful day.

Hi got a sym jet 4 rode it parked it up and now no spark at all help please is this a comon thing 2014 plate to


Hi, Ben and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
3. 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.
4. Loose connection at ignition coil or plug between ignition sensor and module.
5. Spark plug cables in bad condition, shorting, leaking, spark plug cable connections loose check for spark leakage in the dark.
6. Faulty ignition coil or electronic control module.
7. Faulty CKP, CMP, or BAS sensor.
8. Faulty ignition switch.
9. Tilt sensor needs a reset.
10. Security alarm failing to disarm needs reset

WHY CAN I NOT GET A SPARK FROM MY SPARK PLUG


Most sun scooters have a switch under the seat in the seat bucket.it needs to be set to unlock and if it's not connected it will not spark either.

My honda cbr 600 f 1997 iv had the bike for about 2 weeks and it is running on 3 cylinders. I have felt the ehaust on tick over and it apear to be number 1. Any ideas on what it could be?


check spark plug, ht cap, ht lead, then its a case of checking fuel in carb, if fuel ok check jet in carb and slider rubber. if no fuel in carb check floats ok and no blockage of fuel entering carb.

Derbi Senda Xtreme wont start any ideas please???


check your spark plug to see if you have a spark if not check your spark plug cap to see if that id the reason and if its not that check your ht lead dowt it will be that but its possible then check your coil to see if theres any power coming from that .
2nd... you might be starving it from petrol remove your carb and clean it all out remove your jets and blow them to get a dirt out that is in them , then remove your petrol pipes and clean them out to prevent any blockege

My sym jet 50 euro x top speed and acceleration power has died allot recently, i use3d to be able to hit 40 mph easily and now im lucky to hit 30 in around 2 minutes, which isnt good in heavy traffic. now...


Usually either:
1) Pour redex into spark plug hole. Kick start bike with ignition off and leave for a few mins. Then start up and watch the thick black smokey mess come billowing out of the exhaust and run for it as the nieghbours, parents and everyone and his dog complains about the pollution...
2) More likely, sadly, to need a rebore and new piston....

Sometimes it wont start on the electric start even when i bump start it


RS125 Non-Starter Checklist
  • If there is a nick in a tube or you have a leaky carburettor, your fuel could have escaped and evaporated over the course of a few hours (Lift your filler cap and check that there is fuel visible in your tank).
  • Someone could have played with it since you last rode the bike or you might have forgotten.
  • Put the bike in neutral and push along with your feet (or have someone push you).
  • When you have reached a good speed, put the bike into SECOND gear and hit the starter button.
  • If she starts up, pull the clutch in. The problem would appear to be in the starter motor.
  • The starter relay can be found behind the radiator and the connection means that it is possible for wires to fall out of the unit.
  • If you can bump start the bike and the wires are all connected, the problem could lie within the relay.
  • Turn the engine over and make sure that a good volume of air is coming out of the exhaust.
  • If possible, take it off the bike and look for blockages.
  • Make sure the choke is not flooding the engine.
  • Remove the seat and lift the tank up.
  • Either remove the spark plug or take a good plug that you are certain work, and connect it to the HT cap.
  • Touch the end of the plug to the frame via the insulated cap as you are in for a shock (haha) if you hold the plug itself.
  • Hit the starter button and look for a spark.
  • Check the original plug in the same way to make sure that it isn’t the source of the problem.
  • Make sure that the HT lead sits snuggle onto the plug.
  • Make sure that everything is plugged into the CDI as it should be.
  • This is located underneath the pillion seat. Look for bare or cut wires.

Is there a spark at the plug? if so its likely to be fuel related... is the plug getting wet? if so its likely to be air (or spark) related

Put new engine in carnt get a spark at plug sym jet 50cc euro 2004 model


There may be several things causing this fault (your sure the plug is fine?)

The ignition systems on these bikes are pretty basic. The Stator plate provides power to the CDI unit, which builds up until the pulser tells it to send the power to the coil and produce the spark

1. is there voltage from the stator plate (under flywheel) - you can test with a basic multimeter.

2. is the pulser sending a pulse - also can be tested with basic multimeter

3. is the CDI blown? - swap out to test

4. Is the Coil blown? - can be tested with multimeter

it is also very possible that you may have got a couple of wires mixed up when you switched engines.
