I put some frame plugs in the 1199 swingarm pivot holes a few years ago, see pics. I recently bought an ABBA stand so needed to remove the inserts to fit the stand, well the frame plug had managed to trap loads of water behind it over time and caused quite a bit of corrosion. Just a warning to others that have these frame inserts, take them out every now and then to make sure there isn't trapped water behind them. The product is great and I've cleaned the corrosion up and put the inserts back in, I'll just remember to take them out every now and them to check for trapped water. It was the one on the side stand side, bottom frame swingarm pivot.
Thanks for the heads up re the frame plugs. Just checked mine and some corrosion...cleaned them up and ACF50'd Cheers
