GSX250SSM Katana


Purchased in Apr 2020 in Pakenham, this bike came as a rolling frame with the engine unbolted and resting in the frame, and a milk crate of bits. This baby Katana looked almost complete and the previous owner said he’d bought it from an auction and that he was assured that it did run. His intention was to change the motor for a 350 two-stroke that he had lying around. I am glad he decided to sell it before going any further.

The baby Katana was last registered in 2011 (as removed from the windshield.

Work done

  • Reinstalled the motor
  • Installed used airbox and new intake boots (both sourced from Japan). An airbox came with the bike but its a mystery what bike it’s for.
  • Bled front and rear brakes.
  • End cap for the muffler. Quick respray of the exhaust.
  • New battery
  • Cleaned carbies and added sealant to the float bowl gaskets. They were really cracked and broken in places. New seals ordered from Japan.
  • Fixed a coolant leak.

At this point, the bike is not starting and I suspect a dodgy CDI. Further investigation needed.

Work to do

  • Get the motor running again.
  • Add original tool kit (on order from Japan)
  • Recover the seat
  • Re-mount body panels
  • Fix broken rear left indicator

First start. The motor was going – look!

The bike then sprung a coolant leak out of the pipe in the front of the head and now won’t start.
