MC21 wire splice doesn't affect the neutral light.

It will wear out faster though because you'll ride it more often becuase it'll be a much nicer bike. Then of course you'll ride it faster because it'll go faster. Then you'll get nicked by the old bill because you'll be riding it like a hooligan all the time, upsetting old ladies and the like. Every traffic light will be the start of the high street GP. etc etc.

So actually no, it won't wear out faster because you'll lose your license and you'll be sitting in the garage polishing it because you ain't allowed to ride it. Ho ho ho.
