Help beside my CBR 250 crap bike?

Alright i know i have a crap bike, but when i ride it sometmes it just loses power close to it has no spark or fuel and if i back past its sell-by date the throttle it will stall. It's sort of random and i cant exaclty stop and check everything when it happens cos i am usually on the freeway or something. i checked the fuel sstem but it seem all ok, pump works filter works, tuned carby's. Does anyone know if the spark unit plays up or the coil pack cause that intermittent failure? Or is it something else?

Do anyone know around the trial model...

Coil packs could be overheating or timing might be slightly rotten.
are you stupid
take bike to the honda dealer

Go on sumoto.com.au buddy ya bikes ****, time to permit go!!!

Does everyone's computerized EFI do this?

I agree beside fordman.
i reckon the coil is overheating.
Does it start when it cools?
Check for a spark when it does this again

What is CVVT surrounded by four...

CBZ EXTREME? is it fit for me?



Answers:    First stale, when it poops out and you're setting on the side of the road, will it restart in a couple of minutes or do you have to hang around a half hour or so? If a few minutes, make sure the vent on the gas hat isn't plugged. The next time you're going along and it starts to sputter, reach up and crack the sunhat open, if it straightens out, clean the boater vent.

Take an extra spark plug along with you the next time. When it dies, verbs the wire, pop in the extrta plug, lay if on the engine near metal to metal contact and crank it over. If you don't see a spark, then it's ignition and not fuel realated.

If it has to set for a while but later runs fine for a while, I'd suspect the Hall sensor, signal generator, pulse generator, there's a handful of names for the same item. It's the little thing that takes the place of the aged style points on the end of the crankshaft. It's probably a little cube or cylindrical entity with two wires coming out of one end and the other ending pointing closesly to the crankshaft. If you can remove the cover and expose it, run the bike and when it dies, pull over and holding the can upside down, spray some compressed air onto the pulse generator. Upside down and the gooey exiting will be VERY cold, so don't be stupid and squirt it on your finger. Give it a couple of seconds of squirting and see if it restarts, if so, you have found the problem.

The ignition coil (coil pack within your terminology) can go bad, but if bleak, they usually go to missing when hot and don't fail completely. When they do go amiss completely, they stay that way. A bad coil may craft the bike run crappy, especially under hard accelleration but will seldom get it die completely.

I suspect the pulse generator. They are expensive little guys, so check at a salvage yard. As far as checking the resistance with an ohmmeter, forget that, I've have them check out 100% good and in realness they were 100% bad.
