if you are inventive you could make some sort of jacking bolt with a small point to force it out, but with a flat base for a level and to protect the carb.
are you trying to push the broken tip down where the mixture screw goes ? if you are your going the wrong way !!!!! push it from the bore of the carb up and out of the mixture screw hole. it'll never come through the tiny hole in the carb mouth.
thats a nice bit of kit but way to expensive i think !!! mine was free but not as trick. i find pulling the clutch lever near the end also helps, still not as light as other bikes but a big improvement.
I had an old small screwdriver that I cut a groove in the blade, and gently tap in-between the head of the pin and the post if theirs enough room, the downward tap is safer that a side tap.
I suppose it depends on what hub you are using ? if its a wide one then the spokes will be further apart. the size (width) of the rim won't make any difference but a wider tyre might !!!!! are you using kat forks ?
