Hi, hold the mode button for 5 seconds,then still holding it turn the ignition on,keep the mode button held for 15 seconds with the ignition on and the spanner will go away.

if not repeat the procedure again.

Hi there,

Bikes arent meant to be tipped on one side that explains why it won't start. The fuel "wet" the parts that needed to be dry in order for combustion.

Here's a quick solution for that.

1. remove the spark plugs. dry it. and let the air out of the engine block for a while. Return spark plug after at least 10-15 minutes observing the proper torque. (1/4 after finger tighting it)
2. Do not pull the choke. Just start it normally. If it doesnt, jump start it on 3rd gear.

please do let me know if it works, this is what i've been doing whenever someone calls me with a similar problem.

Hope this helps,
please rate if it does,

hi, if you hold in the small button on your left handle and turn the key in the bike to turn it on, do this about four times and be sure to hold the button for 10 sec each time.

Sounds like you lost a gear or broke some synchros in the trans box check all your options first
check all the clutch plates and steels make sure one is not shattred that can be a simple DIY

to get rid of the spanner... hold down the mode button for about 5 seconds..then turn the ignition on still holding the button. and hold it for another 10 15 seconds. should stop it coming on

when you look at the cdi you should se a recess in the corner just a small little recess , enough for a small drill bit to fit , drill the small nipple located in the recess
and i am no expert , just persistent at researching the net

its cheaper and better to research the internet than to get anwsers from people who dont know the anwser

cdi its the same principle cdi is cdi

Water coming from your exhaust is very bad. Best case scenario is a blown headgasket that can be replaced and then go on. Other possibilities are cracked or warped head or cracked block. All will require at least removal of the head to repair.

Did you really mean exhaust smoke, or simply bike is overheating and blowing steam out the radiator cap? If simply overheating the first thing to check is your thermostat. Remove it and test in a pan of boiling water. Does it open? If not, replace it.

DO YOU HAVE ANY ANTI-THEFT DEVICE
START THERE AND CHECK WIRING FOR DEAD SHORT
IF NOT, WHAT WAS THE LAST MODIFICATION DONE

You either have a dipstick or sight glass to check your oil level correct? This same oil lubrcates your transmission..Use the best oil you can get 10-40wt. ...Good luck to you friend....Tim

Check the fuses. Check the operation of the ignition switch and all kill switches with a volt ohmmeter. You should be getting power into and out of the switch.
Check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires? Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center casing.

in regardes to your fuel problem you must find out if you have fuel going to your carb remove fuel line at carb to verifie you have fuel there if fuel is present then you have to remove carb and give it good cleaning. if no fuel is present check fuel filter fuel tank screen and sediment bowl at the petcock. hope this helps you out jim

there's a rev limiter . Im not sure of your bike model but a simple google might help.

If this is the same as the RS125 cable i changed then the cable goes into the clutch cover engine casing yes? You do not have to take the whole engine apart you need to disconnect the cable from the lever and then you will have to take the clutch cover off. before you do this you will need to lean the bike on its side as you will lose the gearbox oil otherwise. plus the cluch will fall out as it is held in with dowels and not bolted (stupid design) once you have the cover off then you can disconnect the cable. if your gentle when taking the cover off then u will not have to replace the gasket however this rarely happens you will deffianly need to get a new gasket about 4quid. reconnect your new cable and then put the gasket on and be carefull wen putting the casing back on the engine making sure you do not damage the new gasket.
hope this helps.
