My sump plug is immovable any ideas? or is it best left to experts also is it possible to change completely to full wiring harness and clocks of another duke say one of the monsters? as i see it changing to a later bike electrics saves hassle my charge system has gone again!

More force needed!! With a socket and tommy bar use an extension to get more leverage, like some steel pipe or large adjustable spanner (the hole in the end of the spanner can hook over the bar). Don't be shy, give it plenty.
