1989 Honda CR 250 rebuild

Bike was listed as “locked up”, but very low hr bike. Pretty much everything was original except FMF pipe and silencer and bike was stored inside.

The last time it was ridden it sucked in dirt. Crank was sent to Ken Oconner for rebuild.

In seizure cylinder wasn’t damaged but plating was flaking pretty bad. Cylinder with Pro X cast piston was sent to Powersealusa.

The chassis on the bike was clean and original. Just a good cleaning and regreasing. Shock bumper was missing, so it was dropped off for a rebuild.

Carb had 58 pilot and 178 main. Previous owner also had a reed spacer on the intake with an FMF gnarley pipe.

For Racetech fork springs owner had to make make a pvc spacer as the new springs are 40mm shorter than originals, stock springs had a lot of preload on them, owner went with a lot less at the RaceTech recommended 4mm preload.

Parts

  • Pro X rod kit
  • replaced all bearings and seals
  • new seat
  • Boyesen reeds
  • yzf pegs
  • SFF forks
  • Excel rims
  • PC raw pipe
  • OEM clutch cable and intake bolts
  • Works Connection frame guards
  • Racetech fork springs
