All,
Just got a groovy Y piece from Daz (thanks) and merrily undoing exhuast nuts on the original cat etc etc, but when it came to removing the Lamba(?) sensor, it seems to be stuck fast. Got appropriate size spanner to it etc with no joy. I presume that it is conventionally threaded, and not a reverse thread, or am i missing something really simple here. Bike in bits....HELP!!
