It is obvious that you need a new pick-up in the nose cone.
FWIW: An ignition problem will usually result in a "hard" miss at speed or under load, a fuel miss will usually result in a "soft" miss almost any time even at idle. I know this is kind of an ambiguous description, but is the best I can come up with.
Others on here will surely have their own "best description".
The reasoning: When a cylinder mis-fires the engine is still forced to push that piston over through the compression stroke, thus ignition. When it is a fuel problem there is always the chance that some fuel will enter the cylinder and produce a little push, not as much as demanded but a little help. Excess fuel entering the cylinder should be obvious with black smoke out the exhaust or fuel running out the air filter.

I'm hoping that this cam sensor is what is part of the cause. Going to clean the carb this weekend so that may help too.

Best to do one thing at a time! Changing that pickup is a good idea and may transform your bike. Some years ago I had problems, with what initially was a simple misfire, but over a year or so got steadily worst, before finally failing - in the outside lane of a major highway! Well worth fixing before that happens - I had to be rescued by the Police.
