Emm alright thanks.

There was one night about 11.30pm on a deserted stretch of PIE, i accelerated a bit more and rode at about 110km/h (gear 6, vtec on) for 10seconds, suddenly the engine died. Throttle totally no response. (Its as if i pressed on the engine kill switch. ) I quickly signal left and let the bike free wheel onto road shoulder. Turn off ignition key, and turn back on, push start, and everything back to normal. Dunno what happened though.

 

Happened to me b4 but mine when turn off ignition and back on,push start cannot start, need to on/off the engine kill switch then can start again. and its not the first time.

[FrdAuZ]

Was it normal day or rainy day?

[isymn]

normal days..but mybe due to heavy rains recently then the wire at engine kill button short circuit..jus maybe

[FrdAuZ]

I thought that too, my friend said maybe wire harness or something to do with engine computer etc cos just now rain heavily and bike feels damn heavy(throttle wise)..

 

Hope its just a one time off thingy..

[LXY]

Ur plugs?? Did u change them as well??

 

ya i changed NGK Iridium plug abt 2000km ago during may.

[LXY]

When was the last time your battery was replaced?

 

i dunno.. but the battery is charging when i open throttle. magnetic coil just changed. during cold start, sound like something get choke can't flow smoothly like out of tune like tat leh?? i increase the idling rpm still the same.

during rainy day, road is slippery causes the tyre like gliding the surface that y when open more throttle still like cannot go faster rite?? do u mean that??

wanna ask all the old birds.. some time ago, my bike cannot start due to some problem to the starter carbon as a result i have to knock the round thingy on the left side then can start alrdy, otherwise have to push start.. but some kuku shop change for me then have even 3 months have to knock again... not even 1 year this is the 3rd time i changing the starter carbon, went to another more reputable shop and say might be the starter motor.. any suggestions?

The possibility is there but knocking normally meant to shake of any carbon dust but not the coil inductor (amature if that's what its call). Did you observe them when they were doing it..like using compress air to blast the starter motor amature and its inner housing?..could be carbon dust still trapped inside..just a guess.

If you look at the starter motor from the fontal top, there is a wire like connection with a insulator cap cover..see if you can slightly lift it off a bit and see if the connection are proper..what about the starter relay?

can just see or need to remove the tank?

[Ah Pek]

can just see or need to remove the tank?

 

No..nothing to do or near the tank. The starter motor is just a small cyclinder thing like sitting on top of your crank case and behind the engine block. Should be able to see from the right side of ur bike.

[FrdAuZ]

The funny thing happen on my

Bike again... Rpm 8

Cannot even open vtec and speedo go back to 0km/h...

 

Bike like stuck2, no petrol come in.. Throttle feels heavier..

Check whether you are in first gear if it is clutch in and start or check ur side stand whether its up or check ur kill switch is on.
