Thanks for that link, good reading there. I've already lapped the cases. From everything I've read and heard, the center case gasket is needed to keep everything in the correct tolerances. Those few thousandths of an inch can make a big deal on the 86 250r engine, from what I've read.
Good news..The correct center case gasket showed up today. I'm going to start re-assembling this beast today.

Cooling system pressure tested and motor leakdown tested. Everything passed.
Motor is back on the bike and exhaust is on it. I got the front sprocket and the new uni-filter on tonight also.
Tomorrow I plan on Cleaning out the carb, and starting some heat cycles. About all that's left I have to do is Change the front wheel and rear axle bearings, replace the old rear sprocket, and Put on the chain. Then its onto decals and all that other stuff.
I actually put this all in by myself, my neighbor that always helps me wasn't around tonight...I think thats why I'm spent.

I'll facetime you tomorrow when I go to fire it up.....I polished the rear grab bar, and one wheel with some mothers....it shined it right up.
looking good Fred. Hes gonna be totally shocked when he gets this thing! Hope you put up some vids when ya get her running.
Thanks Jared! I plan to take a few vids of it heatcycling...hopefully tomorrow at the latest.
I did get the Rear Bearings changed and the bearing carrier, the one that was in there was jacked up. Luckily my friend down the road had one, and gave it to me.
The chain is on, and the rear sprocket is replaced. Tomorrow I have front wheel bearings, and This thing is getting fired up for heatcycles. I'm going to take a video of it when I do.

Here is the video. I want to thank everyone who helped get this done. KOR for getting the cylinder done, and rounding up parts, Justme for offering help and looking for parts, My buddy Raymond for giving me his 250r parts stash, and My brother Nick for doing this for the Old man.
This is the second heat cycle, The first one it fired up in about 5 kicks, I had to set the idle, and play with the air screw, but got it. I found out after I did the wheel bearings, it needs a-arm bushings. Ordering them in a bit.
Enjoy!
