The 2 main frame bolts - 900ie / 900

Hi All,

Been busy doing lots of trial fitting on my 900 build as bits come back from powder coating and the local engineering place.

A quick question that I'd like info and hopefully advice on. I have a 900ie engine going into a 900 carb frame which fits fine with the known exception of the different sized bolts that hold the engine to the frame. I understand that typically the frame is drilled from 10mm to 12mm and the newer type bolts are then used which is I'd imagine no big deal, however on mine the rear bolt screws into a captive nut in the frame so cant easily be drilled out unless it was and then re-tapped to 12mm. Is this unique to early 900's as I thought it was just a long bolt with a nut / washer on the end of both?

Cheers,

Ben
