this has become irritating
ill be riding along (i dont rag my bike i go the limits) and suddenly the power dissapears and the engine dies. This occured 3 times today there was no difference in my riding, it just cuts out
the bikes carb has been cleaned out the tank has been scrubbed on the inside
any ideas??
HELP
i love my bike
Next time it happens remove the gas cap and listen for a sucking sound.
ok what will that mean/do
Fuel tank vent is not venting.
If you gave up a clue as to the model of bike that would be a big help. Maybe a photo of the bike?
Some tanks are vented by the cap, others by a charcoal canister, or a hose.
sorry yeah its a superbyke rsr 125 same as a sinnis stealth 125 got a suzuki gs copy engine in it
quick update its now momenteraly loosing power and back firing an awful lot will put it on the rolling road for a diagnosis tomorrow will let you know the diagnosis so if anyone has this problem they can refer to this as problem to see if it helps
ignition coil and spark plug how simple.
Glad you got it solved and thanks for reporting the solution.
cheers for suggestions dude
wasnt my coil problems still occuring
check the electrics of the bike, well, have someone check the electrics for you, the box that tells the spark plug when to fire could be
1) buggered and not doing its job correctly.
2) not getting the power it needs to make the spark plug spark
of course you could try a spare battery,
it could also be that there is something waving around in your air intake box and periodically stops air getting in and so kills your engine.
i had a similar problem, i ended up replacing a couple of black boxes under neath the sear and on under the fuel tank.. no more problems with the bike.
changed the spark plug and then after a week and a half the plug was dead am now running with a cbr600 spark plug altho i feel as thon it might be going again and it HATES cold starting needs to run with the choke for at least 5 mins
humm, what was the color of the spark plug??? you can sometimes tell whats wrong by the color of the spark plug.
it could be the mix has sodded up some how....
sorry to see you arnt in china, if you had been here, you could take it to a local shop, pay 20 pounds and let them work on it for a couple of days straight until they found the problem. in the UK that would cost more than the bike :-S
wonder if theres any chinese machanics near me LOL the colour of the last plug was black also a black oily residue around the outside of the plug hole itself
