haven't looked here for a while, apologies for appearing rude.
Both K's are not running, had the K2 since late 70's and K6 since 80's. K6 I bought from a friend crash damaged and repaired it then it got used for years of commuting, stuck in snow a couple of times, got quite tatty used to be able to leave it anywhere but probably not any more. This now needs a full restoration but is still complete.
Used to build all sorts of engines for other people, and pick up on problems that were difficult to solve. Just enjoy mucking about with anything technical really.
Other bikes currently are Triumph Speed Triple 1995 (metalurgically challanged, needs new starter sprag clutch, just about the last component right inside the cases) nice bike though plus CBX 750 1984 on the road and current user, nice bike and maybe last 750-4 air cooled Honda?
