Question about 2006 Izuka S125B

1 Answer

I detected a problem in the ignition system: Izuka S125B starts OK but after few seconds stops. I checked there is no spark until a few trials, bike starts again, and again spark is missed. I wonder if ignition coil is the problem. Thanks for your help

The problem is with the timing chain which rotated the inlet and outlet valves in cylinder with the help of cam drives.
sometimes due to contineous operation of the engine the timing chain enlarges and due to which the timings of the valves changes awhich leads to the change in the ignition timings.
change your timing chain and it would be O.K

2004 fat boy won't start

First check for spark by using a known good plug and laying it on cylinder head while cranking. Leave the original plugs in. Do NOT remove them for this test. If no spark then either crankshaft position sensor or the ECU or the coil or system relay or fuses or wiring is faulty. If you do not have good electrical knowledge to check these out, bring it to a dealer. If good spark, then fuel must be the problem. Check to see if fuel pump runs for a few seconds when turning bike on. You shoud hear the pump running for a few seconds then stop. If the pump does not run, check system relay and fuel pump fuses. Note - the pump will only run once when turned on/off every few seconds. Bike needs to be off for at least ten seconds for next pump cycle. Check to see if faults codes are stored in ECU memory as these may lead you to the cause.

My 2 stroke trials bike wont start. I thought id gone into reserve tank when the engine just died. Got heaps of compression still when i kick it over and it was running ok up until this point. Do you...

Hi, Christopher 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.

The bike was running last fall but will not start now but the plugs are not getting any spark, the bike will roll over though.

Is the bike an electric start or a kick start? When you say that the bike will roll over, do you mean that the motor will turn over? If it is an electric start, then it should be able to turn the motor over easily for a few seconds. If it drags or slows down quickly go right to the battery and check open circuit voltage or have the battery load tested. If it has an ignition module, then it might not start to trigger until a certain cranking speed is reached. This a common problem for batteries that are left out in the cold during the winter months. You might just need to give it a charge with a trickle charger. If the battery is OK, then check for power at the coils using a test light. If there is no power at the coils, then check for a fuse or fusible link. If there is power, then it could be a failed ignition module or CDI box. You might be able to have these tested at a bike shop.

My Yumbo Dakar 200cc bike dies after riding in 5th gear reving medium-highish for a couple of minutes, it usually just dies after i hit the clutch (coasting), but on long runs @ around 50-60mph in 5th gear...

I have a couple of ideas what may help.
First I would think it was starving for fuel.Or maybe an unusual ignition system fault- So how do we find out?
Well-you could try checking the bike for spark immediately after the bike stops.
Remove the spark plug-Re-fit to the cap-place plug resting on metal where you can see it(DO NOT HOLD PLUG-HIGH VOLTAGE)-kick over & check for spark.If theres no spark-try a new plug but if the problem persists then the bike has a faulty ignition(coil,cap,plug,stator.ignition/kill switch,wireing)
I think it is more likely starving for fuel.
A faulty fuel tank filler cap vent or carby vent tube pinched or blocked.
To check the filler cap-ride the bike & when the problem just starts-quickly crack open the fuel tank filler cap to let air in/out. If bike runs ok then the cap is blocked.
To check the carby vents -just look at them & make sure none are blocked or pinched.They usually come from each side of the carby & one from the bottom(usually clear or semi-clear hoses).
I hope that this helps you with your problem.

I have a 2003 honda shadow vt1100c spirit. it will not start but turns over fine. spark plugs get fowled with fuel . using the choke doesnt seem to make any difference, but it feels like its working ok. a...

Sounds like itermitten spark.Clean stator with electrical cleaner(under flywheel)then replace spark plugs and check for spark.then the electrical componets to check are CDI ignition box and coil.If either of these go bad you will have no spark.Check also the condition of spark plug wires and rubber boots these can somtimes dry rot and go to ground shorting out wire to plug cuasing bike not to start.

I have a cb1000 big one with total power failure . bike started ran for few seconds n stopped dead . have checked battery , fuses , ignition , earth and cant find any thing obvious .

Has the engine seized up? If it cranks and all seems to be in order, rev counter, ignition lights, fuel etc. Check for a spark at one of the plugs. If no spark I suspect the ECU.
Hope that helps.

Aprilia mx50 will kick over then stop after 5 seconds kick over again and will stop after 2 seconds, then wont start, leave for a few mins and will kick over and will run for 5 seconds and so on, any idea...

If your bike starts even for 5 seconds you should investigate your fuel delivery system.Check fuel pump,filter,try spray carb cleaners like Gum Out.Most importantly make sure your choke is working.You got your ignition (spark) it is most likely fuel related.Good Luck.

ProClean is good stuff but not worth the money. The only reason I had it was because I won a create of it at our clubs Supercross race it's too expensive in my opinion. I buy 40 litre containers of stuff called TFR which stands for Traffic Film Remover, it basically is a detergent like ProClean, Simple Green and all the others, only it costs a fraction of the price and isn't deluted. This means you can delute it to your own strength for different causes. You can see it removing dirt as you watch, like someone said above. You can not use it pure on the bike however, it will make alloy parts go dull - as my buddy found out lol. ,,,
