If you were racing it, ( which i dont think you will be ) not very long, but just for the occasional outing, ie, a few trackdays or parades, i would have thought you would get away with a couple of years before thinking about it. Of course if you still have the high first gear in that will hammer it unless you go gently with it. Be nice to see a few piccies as well, not too many NF5,s on here.
