1200 Cough

[GelandeStrasse]

Before I take a day off to go to my nearest dealer for a diagnostic, anyone had the cough/splutter symptoms when putting the engine under load (ie overtaking). The bike seems to not want to respond to large throttle movements at all.

I've put a new plug coil on what I thought was a dodgy one, but it didn't change a thing.

Anyone any ideas?

I had the same thing twice now, turned out to be a dodgy plug each time

I only had it the once but it was also caused by a dodgy plug.

Thanks guys - but did you mean spark plugs or plug coils, please?

Plugs on mine The dealer tried changing the coils at the time with no success, then back with the original coils and new plugs all was OK

Ok, will try new plugs this weekend and let you know!

I did a bit of testing on the plug coils, swapping a new one at all 4 positions to find out if there was a dodgy one of those. No change! It was tricky to get the lead to connect on a straight coil for the underneath sparkplugs, but I managed it by taking the tywraps off the leads on the right cylinder, slaving in the new coil (just reached) and when it came to checking the left cylinder I swapped that coil over to the right (and noticed that they are handed, just to make it even trickier) as the leads on the left cylinder did not reach to a straight coil.
