Set myself a summer project of curing the Griff 500 shunt.
Surfed PH for all the fixes over the years & listed easy/cheap first to work through.
Started by cleaning the stepper, doing away with the plug extenders (temp trial with socks) & changing the NGK plugs from BPR6ES to BPR6EIX.
Was expecting to work further down the list than this but all hesitation now gone and pulls from idle in 5th gear! - delighted.
Not the best problem solving technique changing 3 things at once but will take the result and have no intention of reversing the changes to find out!
If nothing else it at least tells me that for my car shunting is not a feature but a fixable fault.

Nice one. I have always cleaned the stepper every 5,000 miles as part of a minor service.

You may find the shunting disappears in lower temperatures due to a slightly richer mixture and cold inlet air.
