Hi all first post, I just wondered if anybody knows the thread length of the gear box oil drain plug , as I would like to replace it with a magnetic one to catch any nasties.
Cheers

The gearbox oil level check plug (fill to spill) , is the exact same as the drain plug. If you remove the fill to spill , measure it and you should not loose any oil …

Perfect, thank you very much indeed for that tip I will give it a go.

If you find something that works, please post. I've got a magnetic plug on the engine side but have never seen one for the tranny. I'll bet lots of us would go after one.
 
Will do, shortest I can seem to find is 15 MM , tranny plug is only about 10 mm long , will let you know after the summer when I change the oil , also have gold magnetic plug for engine after oil pump issues , strainer ,non return value and new oil pump fitted by Norton, all seems fine now though.
 
I have changed the engine oil sump plug for a gold magnetic one with a traditional hex head already , no issues.
 
I drilled a recess in the end of the plug, then attached a magnet with JB weld, however I thought the later bikes were fitted with magnetic plugs?
