small amount of lube is all i use showed the young fellas how to do it at the dirt track last year they had been fighting with it for about 40 minutes, got it on in about five. showed them the basics and the rule for bike tyres is ( if your fighting with it you're not doing it the right way watched) them do one on a mini that i had a bit of trouble with and came to the conclusion that they need heaps more practice.
