im reposting this question because i missed out a few details and i need a reply.
im really new to motorbikes, so any help would be greatly appreciated.
today my bike died whilst i was driving it, about 10miles into a journey, and refused to start. it won't kick start, and won't even bump start. the engine cranks, but thats it. and it didn't just stall, there was a loss of power- i noticed it slowing down- and then slowly came to a halt. but lights, horn, etc work, and the starter motor turns.
what could it be? the KILL switch is on RUN, it has a new spark plug, and it sparks.it has a full tank of fresh fuel, and the spark plug is wet when i crank it.it makes no difference if the choke is on or if the petcock is on prime or reserve. the battery is fully charged, and connected
what the hell is it!?
the engine cranks and sparks- but it doesn't seem to want to ignite...
i dont know if this helps, but i can feel air coming out the exhaust when i crank it
any feedback appreciated
thanks

Your problem is quite common for motor bikes.You have small partical stuck in your idle cicuit jet.You are not getting fuel into the engine because of this plugged jet. Take the carbureter float bowl off and with a ssmall screw driver remove the idle jet. Take a fine needle and clear the small orfice.You may also try compessed air.Once you can see light through it put it backtogether.You may need an in line fuel filter.

For a bike to run it needs a few things but mostly fuel and spark.
Since you have fuel then we know you are not out of petrol, you have spark so their should be ignition.
The answer could lie between the 2 , I am guessing blocked fuel filter first , the fuel pump second.
If it is still a carbed bike try cleaning the bowls and draining the lines, you do this by removing the inlit hose to the carburettor and allow a small amount of fuel to run through, this helps remove any crap that the filter missed.
Check you carbies arn't blocked and that the float is working.
In the end it comes down to process of elimination, you have fuel you have spark you should have ignition.
If you dont then there is something inbetween this process which isnt working

I think biker boy might be on to it, you have fuel, you have spark,
is the plug wet or dry when you take it out after turning over , if its wet then check your tappets with a 4 stroke ,and crank seals if it is a 2 stroke,also check that exhaust is not blocked if its a 2 stroke . the thing they need besides fuel and spark is compression, you haven't given us much to work with
a brand , model, size and weather 2 or 4 stroke would be nice
right now we know what it is, does it have a vacum fuel tap ?and is the hose for the vacum connected ?and is the tap diaphram working, if you remove the vacum pipe from the intake manifold and suck on it petrol should flow through the tap to the carbs, or it can be tried with tap in the prime possition, also there may be an in line filter bowl on the tap remove that and see if there is any crud blocking it this is a common failing on most jap bikes cause they are rusty inside before they leave the factory

in case you have checked that a spark is cutting-edge and your optimistic gasoline is getting via, assuming you haven't any longer been 'tickering' with the electrics. i could say you ignition timeing has come lose and the static plate has been slowly shifting (subsequently the lack of ability of power over short era). i could get the timing checked (an vendors handbook assist you to be attentive to ways you're able to do this). additionally examine theres no water in the carberator (as an exterior possibility). wish that facilitates.

I know it's always nice to be able to work on your own bike but I think you should just take it to a qualified technician. I know this isn't much help but you seem to have tried everything. Good luck!

Borrow or buy a compression tester- No compression equals no start. Period !!! You should always start trouble shooting with a compression test. Check it out and go from there.

Sounds like your ignition timing might have slipped.
