£130!!! times have changed :confused: highly strung two strokes are murder for self distructing in first and second... i managed to melt an RD400 three times in the space of 500 miles(way back in the day when pistons and rings where cheap and power valves hadnt been invented)
if you let the motor reach its rev limit in first and second (ish) because of the low speed ergo low wind resistance and drag, the whole drive train goes slack and im pretty sure any lash in the motor causes enough vibration for the piston skirts start slapping against the liners, a bit chips off the skirt causing an imbalance causing more slapping and it quickly cascades into a disaster

over reving is much less important at 30mph (ish) and above as the wind resistance keeps the drive train nice and taught
