Balancer shaft seal replacement

And still not getting the riding I was hoping to cause of colds and flus seeming to replace each other.

But this winter while looking over the bike and replacing a cylinder base gasket after starting it up it was not running good at all so carbs were next.

Then relocated the crank case ventilation into a catch bottle:

And caped off the air box with a pen cap and some duct tape:

And after just a little riding there was some oil in the bottle:

So stripped the bike to get access to the ignition cover:

Laid bike on its side to not have to drain the oil:

A piece of paper to organize the bolts, notice there are washers on 3 of the bolts:

Pried out the old seal:

New compared to old, part number: 0760122050

Hammer and socket to drive the new into place:

Made sure it was nice and oiled:

New gasket in place part number: 60030040100 This gasket can usually be reused since its a metal gasket. Used a coulpe of lengths of threaded rod to help guide the cover into place since the magnets on the flywheel will try to pull it here and there, make sure to keep track of the 2 dowels:

Had some trouble getting the sprockets from the starter to line up and get it into place, got some help from my dad holding it while it while I squeezed a finger in there to spin the sprockets until it got into place, also had to undo the regulator and clutch slave for it to clear them when using the guide rods, gear lever I just held down while cover passed:

Also found that I was missing a bolt holding the oil pipes and another of the bolts were quite far out lucky to catch this before a major break down happened, even had a spare bolt with the correct dimensions:

Drained the oil from the catch bottle, will see if it separates into oil and water, but have no signs that Im loosing coolant:

Seemed to be alot of oil in the clutch part after having it on its side:

Fired right up after putting it back together.

And after the 20km ride home it looks promising that this was the cause of the oil in the catch bottle but want more riding done before putting the hose back into the air box.

An update, this is what the content of the catch bottle looked like after separation:

And as you can see there is quite a bit of oil on top and some greyish water gunk on the bottom.

Was not able to get similar sample from the catch bottle after the seal was changed since the bottle got a leak and I needed to button the bike up to head for russia.

Might look at bringing the hose back out next summer to get a comparison but from what I could see there was less oil in what was coming out of the ventilation.
