I’m slowly getting there on my RD250 project. So far:
Rebuilt engine, cylinders bored .5mm over.
Ported cylinders to 250LC + specs.
Recut heads, decked barrels and made copper head gaskets to set squish at .95mm.
Made expansion chambers
Rebuilt front forks with stiffer, straight weight springs and (knock off) gold valves.
Revised front brakes, new master cylinder (smaller bore) and braided hose.
Fitted electronic ignition (magneto style)
Rewired for DC charging.
Made a little tailpiece for rear light and license plate mount.
Loads of other little stuff I forget!
Hopefully just a bit more and I can get to testing. Needs a little run in and some jetting passes before next weekend….
