Wishing you the luck this happens fast for you, and sincerely, sorry for your loss. I've been there more than a few times...
Thanks much. Words like this from others actually helps.

Haven't had to add a drop of clutch fluid after I installed the larger diameter clutch pushrod. I purchased it from the person that no one can mention, lol...

My solution was simple, no catch can, just ran the oem hoses into a T, to another hose out through the air cleaner box and down to the frame.

I have yet to see a drop of oil on the end of the hose.
Yep, here is what mine looked like.

Carbon filled the valve pockets on the front cylinder.


Here is what my intake manifold looked like.

Nice and Shiny

Has anyone done the DK “Breather Bolts” instead of the tubing and catch cans and stuff? If so, do you notice any oil or condensation on the side of your bike?

Not DK, but just breather bolts yes. I don't like the breather hoses wrapped around the motor so I went this way instead. Neither of my M8's were / are oil blowers, so no mess from using them.

I wanted to use the S&S filter with the bolts, but as all the aftermarket breather bolts seem to be made at 3/4" long, finding longer ones was a problem, (the ones that come with the Stealth filter are 1 1/2" long).

Luckily I found https://s7ns-noise.com/collections/breather-bolts

would like to see positive results from running the bypass. All the m8’s with the bypass don’t look much better than your non bypass pictures. We’re you getting a lot of oil in your filter?

Cool. Mine doesn’t seem to blow much, if any oil. Just made sense to not recirculate warm, dirty air. Thanks. 😎

Before the mod my air cleaner was dripping oil. You saw my intake manifold, right?

Now I get no oil coming from the breather bolts/hoses since I have gone stage 3 and vented the crankcase. I'm thinking that I could get away with just using Phil's breather bolts now.

I saw your intake manifold, is it possible that going to the stage 3 was the fix and not the external breather now that you have seated rings and a healthy running m8? What level do you keep oil at?
