1988 WR250 revival 2016

Inspiration!

I was wondering when someone would notice them.

he is singing that old song..."ten green bottles..hic...hanging on the floor...thatsh notch rite..hic.."

Lucky the other empties are out of shot!

Oh they were noticed....

And yet no one noticed the lack of a bump stop on the rear shock!

I found the a crack in the same place on my swingarm- luckily I have a good welder.

Hopefully so do I.

I need one...or maybe 6... of those

in Oz, everything is measured by the blma... a drive to somewhere is a two blma trip, replacing a tyre is a 3 blma job...etc

Mowing my oval is a 3blma job.

I thought it was big???

Longnecks JC!

Another small setback, I bought some cases from 2premo, great to deal with, sent some excellent photos, packaged very well, absolutely as described and recommend highly, however my mistake was assuming that '86 250 cases were the same as '87-88 with the exception of the seal flange at the sprocket.
I was wrong. The cavity in the crankcase where the crank wheel fits on the '88 is 115mm across and the crank cheeks are 113.5mm across, the '86 cases are 112.5 across to suit the short stroke crank, I mistakenly assumed that they would be interchangeable.
I'll see if a machine shop can machine the thicker web on the 86 cases to fit the '88 crank. Of course I discovered this after fitting the bearings and crank seal, I hadn't yet assembled the transmission/clutch though!

wow, sorry to hear that...but i guess thats a good find. i did not know that and i would have assumed the same as you..

had no idea of that, very sorry
i feel very bad on that

less than 3mm but HUGE on fitment

I built and assembled a 250 five speed tranny into a 83 250cr bike. The five speed was from a later 80's bike. I can't remember the crank I used. But it worked. Your info is something to think about when swapping parts to make things work.

That's half a mm on a side obstruction. I wonder if it can be machined out using a die grinder with a carbide bit on the case. Or set up the case on a milling machine and bore it out 1/2 mm?
