Normk and I are good friends on the forum. He played the devils advocate during my oil pressure / oil flow modifications. Made me reflect and explain things more thoroughly.

I can see that my last sentence of my last post is kind of an 'absolute' statement and possibly could have been better explained. Maybe like, The case halves were not 'Intended' to be used as a mixed set. If one purchases a solo left or right half and they can not achieve proper alignment it is time and money wasted.

We have all noticed that sometimes there is a little mis-alignment of the crankcase halves at the cylinder base gasket surface. And we do wonder, "Why?".

But I do not think Normk's comment was directed directly at me.

Normk Nothing to do with you and not "upset" just tired of that stuff.

I'll be dropping out of this group but will leave PM open in case I can be of service to someone.

I DID say upper and lower case halves. Now, obviously that is incorrect as the KLR cases split left to right vs top and bottom. However, I did say "case halves". Case halves are case halves, and jugs and cases are jugs and cases. Although I made the ( apparently Cardinal) sin of accidentally assuming the KLR split differently than what I thought, Damocles and pdwestern were quick to point out that I assumed incorrectly. Good on them.

That wasn't bad information, but a case of a KLR noob obviously not familiar with a particular pair of case halves. I don't see that minor snafu sending anyone's repair in to dire straits.

Regarding whether or not case halves ( not jugs and cases) are machined-matched pairs, I've never heard of an engine that wasn't built that way, but if the KLR is I'm interested to learn.

Everyday is a school day.

As far as the welding is concerned, that's accurate. Not because I'm smart, but because an old timer took the time out of his life to give me the lessons I needed to learn his skill. And the things he taught me have proven themselves true over and over as I used his knowledge making countless repairs on aluminum heads that I damaged in my racing days, so I will stand by that bit of advice. Likewise, sharing information and helpful experiences with fellow motorcycle enthusiasts is the only reason I'm here. Hope that cleared things up.

Ride safe and enjoy the upcoming weekend.

Normk The "owner" knows as we've been over this before. All will happen is that he will continue and others will get their noses out of joint because they think it's impolite.

Much of the reason I'm not here much as I don't want to be part of bad information and tired of trying to correct.

shinyribs Normk, I'm not entirely sure who you are aiming your remark to, but if there's something you'd like to get off your chest, I'll listen.

Normk I know that people have swapped left case halves because of a bad bearing race. It apparently went well as haven't heard bad news. Might have to jig up some cases to see what the difference actually is. Some of the machining is clearly done with the cases separate so maybe one of these days.....

It's always intriguing to hear people speak in absolutes without indicating how they know these things.

I know at least one person who makes all kinds of claims and is having to back up because he doesn't know what he's talking about. Be careful who you listen to and make sure they're talking with evidence.

shinyribs Up, down...left,right....it's all a matter of perspective.

Yeah, I meant case halves. Not that the topend of the motor couldn't sit on a new bottom end.

shinyribs You know, you could be exactly right, Damocles. I know the CB's I've gotten familiar with can't have the halves interchanged, but I don't have enough experience with the KLR's to justify saying that. I'm glad you straightened that out.

Not trying to sound like an alarmist, but full disclosure is the only way to go. Good luck man. I hope you find a good, cost effective solution.
Appreciate all the good information, shinyribs; has the ring of coming from someone who's been there, done that, regarding welding!

If the cylinder/cylinder liner fit to the case is unique, I stand corrected.
