I bought my Katana from a mate late last year, and since it already has a Katana Owner's Club sticker on the fuse box I thought I should sign up here!
Optimistically, I have to say that the lockdown has done me a bit of a favour as I've had the time to get it somewhere near to how I want it. There's still work to do on the springy bits but it's pretty close. I have a new set of shocks en route to replace the leaky Marzocchis, and another set of immaculate EFE forks that I'm going to sort with linear springs and emulators.
And, it may yet turn silver....
Once I get the chance I'll start a thread documenting the work to date. I did start one on the Old Skool Suzuki forum but soon realised it's a closed shop.

Right, next thing is to join the club....
