1987 wr 250

Got my eye on one of these to do a resto on. Are they easy to get parts for? What are common problems with them? I would prefer a WR400, but there ain't that many around down under

I was rather amazed that just a couple of months ago I ordered an air filter and a chain rub pad at the swingarm pivot for my 1988 husky. My usual source which will have all the stuff for your wr 300 said they don't have the swingarm piece, have had a few sources in the past but none currently. I found how to look up parts on line for these and a lot of stuff I got about five years ago wasn't coming up. The water pump impeller the dog demolished and cost $10 (approx 3-5 years ago) was $5 at one place but might have been out of stock and $25 at another place.

What goes wrong. Well if they are raced hard or treated like a beater bike the sky is the limit. The plate for the back brake and the swingarm wear a lot resisting the twisting force there. The engine connection to the frame at the rear can jump around and demolish the engine case and the frame in that area. That rear suspention only seems to wear the actual swingarm bearings the linkage stuff is usually good. (not true if it is an 85 or 86 being marketed as an 87) Those bearings and races they run on once came in a kit, the stuff at the bearing distributor doesn't match up real well (my opinion) and seems likely what some of the aftermarket sources are marketing.
