I have a 1995 916 Biposto, all original and Isle of Man supplied, 3 owners from new, 10,000 miles on it. Had it fully overhauled when I bought it in 2021 including new belts and fluids. It has been on display in the Jurby Motor Museum in the Isle of Man since March 2022 where we lived for 24 years before relocating to the UK last year. I didn’t like it the first time I took it out but once I got it singing over the mountain, the sweet engine noise was something else, big grin on my face! Any recommendations on how long I can leave it in the museum without running it?
