No need to get the lump hammer on it, just enough for the torx to dig in and grip.

know what you mean - cheers - appreciated

These things are good if they will fit down the hole, be warned tool station sell 2 sets but really it’s 1 full set in 2 packs and Sod’s law says which ever set you get you will need the other (I’ve got both for that reason ? )

I've used these a fair bit. They are great tools.

Torx bit is the best option. But when not available in the middle of nowhere I have used a small diameter piece of wire placed on the side of Allen hole and then driven key in.

It is usually a case of smacking in the next size Allen, a slightly larger AF Allen or a suitable torx bit. You could do this and try a rattle gun on it for the most undoing impact. A flat screwdriver may also do it otherwise as someone earlier said, cut around the bolt and buy a new cover.

If all else fails, drill the head off, remove the cover and then cut a slot in it, heat the fecker up and undo it with a screwdriver......there is always a way

Dremmel grinder with a pointy diamiond coated bit. Come at the bolt from the outside edge and carve a straight slot. Use a fat flathead bit on a ratchet after.

Ease out reverse drill bit! so the drill works by being lefthanded bit

 

One issue you could find if into Alloy and hasnt been out for a long while is Electrolysis as mixed metals ie Alloy and steel add moisture=them growing against each other so things seize up.

BINGO! - Torx bit, medium hammer persuasion, small ratchet, lots of downward pressure. So, got the muffler off & as suspected carbon build up outside exhaust port explained lack of oomph. Cleaned off & now revving right up. Love that exhaust crack you get when things are clean.

Thanks a lot folks - getting support here always gives me a second wind to have another go at my maintenance / repairs.

Glad you got it out as to the "lots of downward pressure" I have found the old fashioned impact drivers are useful to give the downward force plus the torque impulse simultaneously for future reference
