I had a 79 spitfire that tipped over alot, and a 84 sprintfire nice sled, 340 liquid cooled oil injected direct drive. I put dual carbs and ported it and shaved the heads it was snappy but the direct drive limited top end to 65 or so.
I just put up a 28 by 40, 2 overheads 10 foot walls metal roof smat siding insulated and drywalled Did the work myself except ste prep and concrete and I have 30,000 in it. Osb was 22 a sheet whenI did it
