Nrg power 05 plate problems please help!

Hi i have a nrg power 05 plate 70's polini kit it has a dellorto carb with a 120 main jet was riding eairler and the engine cuts out and will not start again, fuel flies out from where the airfilter there is also a rubber gasket where the throttle slide sits and screws in, that has split (quite a big split) is this the reason? maybe its sucking in air. HELP PLEASE!

 

its gonna be pulling in air there but that wont be why its just suddenly cut out and starting to spit fuel out the filter
sounds like your float has somehow got stuck

 

ok thanks cheked the float thats all free, do you rekon its getting too much fuel or too less?

 

has it been running ok with this jet in previously or have you only just installed it ?

 

has been running fine with that jet in seems to be getting too much fuel flooding the engine, when i leave the bike it for like 3 days then try and start it, its runs like a dream intil it warms up

 

also have fitted a pm tuning exhaust today

 

as it got a auto choke ?

 

yes it has auto choke mate

 

ran fine today untill it warmed up then started over fueling, ill see if it starts in the morning

 

sounds to me like the auto choke is sticking mate you can buy manuel choke conversions or replacement for quite cheap

 

i took the auto choke off eailier and the pin was quite hard to push (its on a spring)

 

have you tested it properly (connect it to bike battery to see if the pin moves up and down freely) if not id do that as it sounds like its not disengaging when the engine is getting warm

 

Thanks will try that tommorow!

 

i dont think the choke is working, takes long to start and when it does it ticks over at about 900rpm on cold start

 

ok fella let us no how you get on

 

when was the 70 kit installed mate how much mileage has it done

 

also whats the tick over like when it warmed up (when its not flooding lol)

 

the same when its warm, and its got 18986 on the clock dont know when the 70's was installed speedo dont work

 

oh right i still think its the choke , when you remove the auto choke give the carb a good clean with carb cleaner as well (remove all the jets and clean the lot ) just to make sure mate

 

yes will do mate have to wait till payday lol spend some pennies on it ill tell you if it starts tommorow morning
