The 2 main frame bolts - 900ie / 900

The frame on mine is 1999 and has the rear bolt screwing into the frame, however it originally came from an M600 but it suggests to me that all the carby frames with 10mm bolts probably have the same setup? (oddly the bolt goes in from the left side rather the the right as shown on the parts diagram).

From memory, I don't recall there being a captive nut, rather just a threaded frame? either way, shouldn't be too big a deal to either re-thread it 12mm or just drill it out for a nut/bolt setup.

The problem is likely to be fitting the larger bolt head, nut and socket into the smaller frame tube as, I recall that I needed to buy a pair of 'slimline' long-reach sockets to fit my crashbar/front engine mount bolt (nuts on both ends) as a standard socket was neither thin enough nor long enough and, obviously the nut on a 12mm bolt will be larger still so the problem is greater but, doable as per Bitza's post above.
