Well, I guess I'm not smart enough to figure out how to get pictures on here.
I use photobucket and then link the photos from there

I've never tried to post pics anywhere before. I opened a photobucket account, but I still couldn't do it. I'll try it again though.

Hi guys, this is my first time posting and this may be and this may be an old thread but I need some expert advice. I have a 93 cr250r. I had my chain snap and slapped a hole in my left case. After reading here and other forums I got the impression that I could swap my left case out with any from 92-01. I found a 01 left case online and installed it. After splitting the cases I found my main crank bearing on the left was bad so I put new one's on both sides. After reassembly the bike fired and sounded good so I took it out. After 2 hours the bike began knocking. So I took the bike to parma daves racing. He confirmed my crank was bad. Well he just texted me and said the cases are not lining up where the cylinder sits and could've cause an air leak which in turn fried my crank. Shouldn't this have worked? Is there something I can do to make it work? Help me out guys!

normally should have worked but if it is true that the cylinder surfaces are not lined up (for e.g. there is about 0,5mm difference) then it can be fixed by machining the cases cylinder surface to be flat. usually if there is an air leak it should have other problems such as high idling/rough running etc. my guess is that the crank was on its way so it should have been rebuild with a new rod/bearing.

So my case half got machined to be correct they were 5 thousands of an in difference .005. PDR rebuilt the complete engine just waiting on my head to come back, ships friday!! I should be RIPPING by next weekend !

Just a note for anyone swapping case halves use feeler gauges to make sure that your case halves are perfectly even. IF they're not you will pull in air and smoke your crank very fast.

nice, work done.

on mine my cylinder base gasket surface had to be machined by 0,02 to be perfectly flat! although it was running normal when i pulled the cylinder the base gasket was sealing only the outer perimeter/area of it! so it is good to check that area too. if the base has to be cut more than 0,01 we should consider a slightly thicker custom gasket (i've used a custom cut gasket) to keep previous C/R
