http://www.thumpertalk.com/forum/showthread.php?t=526278 **PICS ARE ON THE FIRST PAGE, SCROLL DOWN A BIT** Totally my fault, went to long without a rebuild. My guess maybe 65 hours. My parts list is nearly over $1000NZ now... new crank, rod, piston, rings, main bearings, barrel, need to split the cases to get all the bits of piston out. Looks like I learnt the hard way. PAY ATTENTION TO SERVICE SCHEDULES GUYS!!
