I removed my speaker grill about 6 weeks ago. I was also busy doing a kitchen remodel so I got both too busy to ride the Valk, plus I forgot I had worked on the bike.
To be honest, I haven't even run a full tank of gas in it yet, but I did take it out for a few rides to keep the battery up, I must have put on at least 75 miles on it during this period.
Today I was getting it ready for Inzane and just couldn't find the screws for the speaker grill on the bench or in the bike's bags.
I did find them on the engine right by the intake tubes where I must have put them when I removed the grill.....go figure, all four screws just sitting where I left them.
