I find it really depends on where the puncture is. If in the centre of the tyre, we have got it repaired.
CK got a puncture right in the middle of the last rear tyre she had after it was only 120 miles used. Did another 4,750 after repair.
There are certain areas that tyre repaires wont 'plug' - such as the sidewall etc.
Often I leave it to the tyre repair place to give me an informed opinion if they can do it - and if its going to be safe.
I'm also a skinflint!
Other people will tell you never to get it repaired - but to change it instead.
Mr Tyreman will tell you his thoughts I would think.
As we only use our bikes for pleasure riding at the moment - (but looks like CK is geting revved up to do a trackday - who suggested that???) I would try to get it repaired if possible.
