Found a seat for the bike. This is a New old stock Triumph seat made for the 97- 01 Triumph Daytonas. It looks OK on there and is quite comfy, which is rare with sport bike seats.
Not much other progress to report other than ordering items for the big motor. Crankcases are ordered from England, race cams & followers from Australia and a Bob Newby Racing belt drive with clutch, also from England. Bob makes a setup just for oversized Vincent engines. This has a 7 plate clutch instead of the usual 4 or, his old heavy duty version, 5 plates.
Now that I have got the PP256 I hope to get some things happening on this project again.
