G'day All.
It's been a while but I have more info on the whole "wire splice and seizure" thing.
I pulled the cylinders off and found out that the top piston seized because...
1. The motor is 18 years old
2. Had original pistons
3. Had home made base gasket (they forgot to cut out the holes for water flow).
4. Was running slightly lean
5. Was being thrashed by an absolute dickhead
32. Wire splice
By the look of pistons it has been running lean for quite a while.
My rebuild kit is on its way from jap4 and will be sending the cylinders away next week to be cleaned up.
Will let you all know how it goes.
