You mean the actual balls, it looks suspicious, but could be ok, dunno. Don't high speed/high performance bearings have less balls?

The cage has collapsed. The bearing is fubar. Remove top end, split crankcase, replace bearing.
Check your oil pumps carefully for damage. Lots of the bits of a collapsing cage fit through the strainers and ruin the oil pumps.
The pressure pump comes as a whole but the scavenger you will have to get and replace the rotor and ignore housing damage as it runs in the crankcase ::)

So I got my drz back and am slowly running it in, I reckon another 80 odd km's and I'll change the oil.

When I first picked it up yesterday after the engine rebuild it was very quiet, in the last 170 km's it has developed what I can only describe as a ticking sound that seems to be coming from the right top'ish side of the engine (ACCT) comes to mind, though I was told it was fine. the higher the rpm's the higher the frequency of the tick.

Ideas?

Check valve clearances. Don't see why anything should have changed as it was head off - head on. But better check.

Wes, stop being so fcuking negative  :D

wes: go play with your rim tape  :lamer:

LeCap: could the valve clearances be an issue after 170km's since you checked them when you rebuilt it?

Newguy: that was the plan though only intended to change the oil at like 200-250 km's

Checked clearances, they were as adjusted after your off, should be, only six kilometres in between.

Shouldn't. My trust in DRZ engines is a bit shattered. Just fixed botttom end and now the top is starting to rattle? :o

Best to have a look.

based on location/sound my first guess is the chain tensioner

Don't think it's the tensioner. Was fine when fitted, took up chain slack as by design. Can't really break (unlike the older torsion spring type).

Ok so what should I be looking for then other than valve clearance?

Anything up there. Decompressor mechanism, cam wear, or check that the adjustable sprocket is not coming off that freakin' performance cam :-\

Excuse my ignorance here - but doesn't a engine rebuild go along with checking the other things that is part of the engine ?

02/02/12 - RIP Glen - the Arrow of Elliot and the little man with the big heart that truly was larger than life.

You have touched us and left us better for having known you - even if it was only briefly.

For grabbing the moment and living the day It's been way too early that you were taken away
