Title: Aparent chain wear into my left case.
Post by: Hawkeye58 on April 22, 2017, 08:24:54 AM: I have what looks like the back of the output shaft bearing peeking through my left case just behind the front sprocket at the top, on my 1993 Kx 500 engine.
What can I do with this?

were you running a 13T front sprocket?...or an xtra wide chain?

Post by: Hawkeye58 on April 22, 2017, 01:40:40 PM: I run a 14t up front.
Standard Pro Taper chain. No Oring or Xring for me.
I fear the prior owner ran wider chain.

There is a steel insert right there.
If it does not leak it's no biggie.

Post by: Hawkeye58 on April 22, 2017, 04:59:18 PM: Thank you for the info!
Should I discover a leak, can it be JB welded?
Also am I on the right track staying away from the
Oring/Xring chains?

Post by: sandblaster on April 23, 2017, 02:10:06 AM: I whittle mine down so I can run a x-ring :-o

Lots of guys use jb weld...
I don't like it so I get mine tig welded.
But I wouldn't worry, I doubt it will leak.

If you just gotta use jb weld get the Kwikweld version

You can have that case fixed...I've had a couple done over the years. Just find a good welder...but like Sandblaster said...if it ain't leaking, I wouldn't make it a priority, unless you want to....other wise JB should band-aid it for a while

There are a few threads on here, with mixed answers/opinions about x-ring chains...but I myself won't run one.
Same with the 13T front, a few threads on them too...most of them suggest to not run one.

Post by: Hawkeye58 on April 23, 2017, 11:42:39 AM: As I continue my research on this a see all of you guys input, I have come across numerous pics of small rectangles of what look to be that insert.
I see some with it showing in two or three locations.
This looks odd to me.
But, you all have helped me relax and given me some ideas to proceed with.
Thanks a lot. All of you!!

Post by: Hawkeye58 on April 23, 2017, 01:08:53 PM: Sandblaster, did you just sand it down to the desired clearance?
Title: Re: Aparent chain wear into my left case.
Post by: sandblaster on April 23, 2017, 01:56:58 PM: Started with one worse then yours, then I used a porting tool to get it a bit closer then last I sanded with a fine flapper wheel.

Post by: Hawkeye58 on April 23, 2017, 02:05:36 PM: Okay,
Good to know.
I may follow your example.
Thanks!
