Made a start on removing the headers from my Triumph. Fortunately after a good Plus gassing on the lower radiator fixings, the rad came off relatively easily. Made a start on the header bolts with the Erbauer nut and bolt remover set. Was well impressed with that and have got 4 of the 6 nuts off complete with the studs. It looks as though the spanner size, beneath all the rust, is 10mm, which is very small for an 8mm stud. I might struggle with the remaining 2, as the smallest remover socket in the set is 10mm, but tomorrows another day. Don't want to get too confident yet.
