Rocker shaft Oil Leak

Hello All,

Just so happens that I was going to post to this original thread

But it was closed due to trolling. Either case I just purchased a 2013 CB500X and has the exact same problem in the same location as described in the thread. The bike has only 37 miles on it and noticed this morning a small pool of oil on the garage floor. Oil all along the side of the crank shaft and the origin of the oil is the missing cap.

I am quite surprised as well that this is happening and maybe with more bikes than people know. What also worries me is that the recall checks are not getting to the dealers.

In either case I have requested my dealer pick up the bike and fix the issue. Hopefully all will go well. If not I am sure I will be back on this thread to voice my opinions and sending emails and voicemails to Honda.

Attached pic shows location of the oil and second is showing the spread of the oil on the engine.

Yep, looks like the same issue to me.

Good luck in getting this sorted and hopefully an extended warranty or similar compensation.

Maybe we could do with a sticky warning for new owners to check the caps as soon as they get the bike? It's a simple enough check to do.

Above all remember that once sorted you have got a great bike!!

Oh and welcome to the forum!!

Yup, everybody needs to check their rocker shaft plugs.
( I checked mine last week, they were good. )

Put a tool on them, and make sure they are tight.
( I believe the spec on them was 11 ft-lbs. )

Don't make me Google it... Isn't this the inaugural year for this particular engine?

That's a good point.

But you know, we have a LOUNGE here, so we can talk about other subjects.
As far as "moon landings" goes... the interwebz is FULL of information on that subject.
People can do their own research, and discuss it all they want to.

It's nice if all the threads would stay on-topic, but this doesn't always happen.

I asked honda mechs building the new cbr650, and they surprised a lot one they hear this problem happening! This is serious indeed.
I would like to move this as sticky but the name of this thread does not fully give the problem. 'Oil leak' does not specify it fully.

Every one needs to check these bolts, if it is missing don't ride it ring the dealer and tell them to come for it,
if this bolt cap what ever you want to call it goes missing and the shaft moves first of all the shaft and it's
mountings/bearings will be subject to bending forces
they were not intended to have, if it moves far enough to allow the rocker to fall off the end
of the shaft then if you are lucky the engine will stop or go onto one pot but if you are unlucky
and it gets stuck in the wrong place jams a camshaft not only is it likely to wreck the cylinder
head and cam drive but valves are likely to hit pistons and do the engine no good at all..
I suggest you check them now and report any loose ones to your dealer, get them to re toque
them up if it's not reported Honda wont know the extent of the problem,

Who would design a vehicle that falls over when you stop.

Please excuse my ignorance, but it sounds like there is a plug
On either side of the bike? Can you please post pics of them both?
