IT250 trans fixed

There is a blog post I meant to make showing the engine cases split and trans all disassembled. Showing the new crank installed and me confused about what was wrong with the trans because everything looked perfect. I forgot to make that post oops.

So… Turns out the it250 has a spring loaded pin inside the oil drain plug. This spring loaded pin puts pressure against the trans gear cam selector. Mine was missing since I bought the bike.

This is why it would pop out of gear and shift shitty. So technically I could’ve bought the $2 spring and not taken the trans apart at all ha. Anyway, shifts / runs great now.

What I’ve done since owning it

  • New piston
  • New (used) crank / connecting rod that I had balanced
  • yz250 head
  • yz250 swingarm
  • DG pipe / silencer
  • Racetech front suspension with vintage Terry-kit dampers
  • NAMC rebuilt yz250 rear suspension
  • New Mikuni VM36 carb
  • Clutch
