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.

1979 Honda CR 250 restoration

Project –
https://www.vitalmx.com/forums/Bike-Builds,46/Turning-a-1979-CR250-barn-find-into-a-1978-RC250-replica,1343747?page=1

Looks like this bike was gently trail ridden for maybe 20 or 30 hours. The only wrench this bike ever saw was the rear axle nut to adjust the chain. It was pretty clear that the wheels had never been removed from the bike and the original “Claw” tires still had most of their tread left. The grips and levers looked almost the day they left the dealership.

Obvious that this bike not only had not been raced, but it doesn’t even look like the bike had ever been even in a small crash.

The paint on the fuel tank was unmarred and no sign of even the slightest knee scuff marks. The same goes for both unmarred engine covers. The seat still looked brand new, no cuts or scratches. Most bolts still looked quite new and the trans oils looked pretty good after sitting in a dry place for probably close to 40 years. There was a little bit of fading on the front fender, but other than that, the plastic all looked good.

There was no dry rot on any of the rubber parts either which were still supple like new. There were remnants of a mouse nest in the airbox, but this bike is pretty much a time capsule from the past. The few minor scratches on the swing arm and left side plate looked more from having things piled up against it in a garage than riding. This bike is 100% original.. no parts were broken or missing.

In the end the best match for the engine paint was the RAL 3020 Traffic Red form LVP.

For the slightly lighter colored frame, the Tahitian red from National Autobody & Paint Supply was a dead ringer except it only comes as a base coat which is a flat finish and needs a gloss clear coat.

Part list:

  • rear motor mount bracket fabbed by Ray Carlstedt
  • replica HRC bolts,
  • upper motor mount bracket,
  • RC-replica swing-arm spindles,
  • stainless RC replica motor mount bolts,
  • CNC exhaust flange that will prevent spooge dribble typical of the stock bike,
  • vintage D&G front fork air caps,
  • RC replica white gas cap,
  • VMX fenders,
  • heavier .48kg springs from Race Tech 15 weight oil,
  • shock guard to protect the shafts on the Fox Air Shox
