Hey Bud
Ole mates name is Rob
The 420 failed only because it siezed.
Prior to this , it had Completed 5 Rockley Rides ,1 canowindra ride , raced in VMX, completed two Harrows (one being probably the worst because of the deep unrelenting bogs) , more than 10 big trail adventures and been thrashed by more people than i care to remember at 4 classic dirt events .
Not bad for a machine that requires very little maintenance.
Once completely overhauled it will do the same again
You should buy one Bud , my twelve year old nephew could maintain it for you as they are that easy to work on. But he would charge you more than Paul.
