derbi mulhacen 125cc help

[Geeeza69]

hi i need some help identifying a problem with my 2009 derbi mulhacen 125cc
basically when i start it up and set off IL get a few meters down the road and it will start juddering and eventually cut out. it will then take a minute or 2 before it will start again and as soon as i set off it will happen again. if i keep the revs very low and not go above 30-35 i can get a bit farther but will still cut out

any help would be really appreciated
cheers

check your spark plug colour, and see how much spark your getting also. get back to me once you're done

im unable to get to or see the spark plug due to where and how its fitted on the bike as i don't have the right tools to remove it

but the spark plug was new in on Wednesday 6th June as the old one had gotten wet and was very rusty

sounds like fuel starvation, bike runs then empties the carb, bike stalls then takes a couple of minutes to fill the float bowl again

I've been thinking the same thing but thought if ask on here first as I know nothing about bikes

I've only had it a week and it had been sorn and has been sitting in a garage a while when I bought it

how long was it stood?
any idea if it has a fuel filter?

my main thoughts are either crud stuck in fuel tap or in a inline filter.
or state fuel thats then blocks a filter or jets
