I have a K1 and my Zed is my daily driver too.
Drive to work and everything. Absolutely love it.
Consider your Zed a service to your community, because I'm sure that in my neighbourhood, nobody is ever late for work, thanks to the K1 alarm clock.....that's strikes at 6am, lol.
but if you are that worried about the noise, then just keep the bungs in, and once the exhaust had coked up a bit, it will settle.
That had my dad & me in stitches,awesome post.lol. I still want a k1,just got no pennies
