Cam journals
Hello everyone, and happy New Year! Glad there are such forums like this one, thank you. I was referred by a fellow GS enthusiast to ask this community a question in regards to what I found when I was having my motor parts inspected and checked for proper rebuild. I found my cam journal cap for the intake on number 3 cylinder to have a bit of irregularity during inspection. There was no damage to the cam, the bike was running when I did the break down. The discussion was that this journal may have a lower oil pressure threshold than the other journals due to this irregularity. I am restoring this bike for sentimental value, and it is not going to be raced, nor is it my primary steed. Thank you in advance for your input on this.Tags: None

I would simply chamfer that little bit of metallurgical irregularity to keep it from spreading with a die grinder and call it good myself.
Other members will offer their advice too.

Sorry about that, the specific bike I am talking about is a 1986 GSXR 750. I used to own one about 28 yrs ago. I found one on Craigslist that was the same color, and still had the stock red color scheme like I had those years ago. Still working on navigating this forum. Bear with me.

I did not look close enough to notice that it was an end cap with one oil groove.
For those interested, I just took a pic of some common GS parts. The left cam cap is typical for a 2-valve engine. The black one is for holding down the
handlebar and the two on the right are typical 4-valve cam caps...

This is what bad cam caps look like:
I would say as others have done; grind off the edge and put it back in.
As a precaution, I would drop the sump and check the sump filter (if the 750s have this like the 1150s do) and see if there is any metal stuff kicking about. That would give you a good idea of the condition of everything else.
From what I can see, I might suggest that this is not the oil starvation problem I had on my one but more like a part failure (metal fatigue?) or incorrect assembly procedures.
I am no expert but I share my own experience.
GreetingsRichard

Ha ha! Hey thanks for the replies. I did some work on the cap posting a pic of where I'm at. Yep, I have a particular buddy who visits this page. This GSX used to be an old favorite of mine. The motor looks clean as if it were rebuilt, then simply parked. Motorcycles have been my long time passion, dabbled in racing motocross for years, trials riding, supermoto, enduro. I hope this bike feels as good in the twistiest like I remembered. I did take some other picks of the pistons and such to show the condition to wilmrx.Attached FilesLast edited by Guest; 01-01-2015, 07:31 PM.

Is that bear still with you or is it in some kind of pen for the night?

Thanks Ray. GSX, yep bear is in the back yard building a fire it's cold lol! Yes, that pick of the pistons is what I found when I slid the jugs off showing the liberal application of oil on the pistons. The main reason for the disassembly was due to a pretty bad oil seepage coming from where the cases split directly behind the exhaust header. At that point, disassembly was the only option to solve the leak. Going to hone the cylinder walls before re-assembly, and possibly rings if needed. photo(99).jpgThis is a pick of the bike right after I purchased it.Last edited by Guest; 01-02-2015, 01:51 AM.
