Hopefully now the F850 has tubeless tyres being stranded with a puncture will be less frequent.
I have tried various plugging kits with limited success. The one I find best and almost fool proof is made by Bell and was available from Halfords.
Select the right size screw to fit the Puncture, screw it into the tyre until the bobble on the end enters the tyre, snap off the handle, re inflate and ride cautiously until the tyre is swapped or a permanent repair is done. Works very well. Before I found this kit I used to use posidrive decking screws.
The little compressor was only a fiver from a petrol station. It inflates to over 40psi but takes some time. My GS800 standard accessory socket trips out so I added a lighter socket connected to the battery via a fuse.
