I'm a bit lost here if the sprocket was fouling the clutch release there is something very wrong why not repair it? The mod you have done is illegal and will fail an MOT and if your stopped by plod a possible ticket with a strong likelihood you will not be allowed to continue to ride the bike.
That's a really nice project you've got going there How did you get round the problem of the ECU bringing in the rev limiter really early as there's no speed being shown by the front wheel ?Baz
