Did you work out which vacuum port to block when you used a non vacuum fuel tap ? And are you using full choke with no throttle ?
Hi my67xr, I pretty sure that it the hose coming from the crank case to the air intake.. And also tried chock on 3/4 no throttle, 1/3 no throttle and every other combo I could. . May have to get a mechanic to look at it.
No no no ... that will be the crankcase breather/vent ... it has to be open to the atmosphere or to the airbox
Greyimport, oh OK. Good thing I didn't block it off. I don't see any other hoses coming out of the engine going anywhere. Frankster, I'm in Seaford bud.
The vacuum line from the fuel tap would have gone to a barb on one of the intake manifold's. If this is left with no block off on it the engine will suck lot's of air and be very hard to start. Not sure if your intake manifold's are the same as this one it's off a 2010 Megelli 250R
My76xr- I've had a look at mine and it's different, pls refer to pics. So I've striped the bike down again, got spark, can fill the carby sucking for air. Fresh oil in. Rechecked vavles. ALL good in those areas
The carby looking clean & it actually being clean are two different things. Did you fully strip the carby and remove all the jets/emulsion tube/diaphragm & thoroughly clean? Looks like a diaphragm/pump fuel tap, you'll have to prime it to get the carby full of petrol. So it will fire. Did you mess with the air/fuel mix at all?
Hi all again, OK after 3 days of piss farting around, fully dissecting the carby again and cleaned all jets, checked the valves again, checked wiring, checked spark, checked all of it from head to toe.. I ran out of ideas. Out of curiosity I had the old spark plug there and changed it out. Boom thing fired up. Ffs... All that for a sparkplug. But my question now is how could a brand new spark plug fail like that. New spark plug--ngk iridium cr9eix Old spark plug - denso u24esr-nb But that all done and working correctly all I need to do is put the bike back together. Fine tune can be done later. Thank you all for your help.
You can get dud plugs, it's not common though... but plugs are easily damaged, doesn't take much to crack an insulator and make it useless. I would suggest re-gapping the old plug if you continue to use it.
That's a pisser because all of that effort for the solution to be so simple, however on the upside you have now double checked all of your previous work and gained a substantial confidence boost in the process, additionally it's a good lesson that sometimes it isn't safe to assume that something new is definitely working, call it trust but verify
I've had bad experiences with NGK Iridium plugs. Read the post at the bottom of this page... https://2fiftycc.com/index.php?thre...-to-your-bike-today.1701/page-191#post-102659
Hi all again. Just took the megelli for a test ride ride today and noticed that my neutral light is on while in gear? And ideas?
