Well the old girl passed her MOT today with flying colours. Doesn’t legally need one but £25 is a cheap price to pay for peace of mind 
I’m going to treat her to some iridium plugs, what grade do you guys recommend please?

I m checked mine and I am using NGK BPR5EIX but I think the standard recommended heat range would be BPR6EIX

Paul,
Have a read through this thread.  
Spark Plug Options

I am currently running with Bosch FR78X plugs in mine. The bike has been running like a Swiss watch since I started using them so they seem to be perfect for the stuff they sell as fuel here in the UK. Not sure what the purist will make of then though, but don’t knock them till you’ve tried them. 

Thanks, give them a try 

If you're sold on the iridium thing, you don't get 100% benefit on these bikes unless both the center electrode and the outer electrode are both iridium coated (which is not the case for many of these plugs).
