This is embarrassing but they say confession is good for the soul, plus it gives somebody else a laugh.
I have just started my swap to radials. Some would say at last!
Tyres are worn out and seemed like the right time.
However, just removed the right hand fairing panel and noticed a shiny brass pipe. Strange, I thought as all of the 4
rubbers are there.
Then I noticed that one was on the adjusting screw of the linkage between injectors 1&2! No wonder the tickover was lumpy.
Can't even blame drink.
My sincere apologies to those Brazilian workers who make our Bosch plugs for blaming them.

lol ...at least you found it john ....

cheers mate

He really had me thinking after talking about the 'right hand' fairing panel removal.......

Well, it was the right hand panel looking at it from the front of the bike.
Think I was just that relieved that the problem had been so simple to fix and not HT leads, Hall effect sensors, etc.
