Anyone doing the breather bypass on your M8?

I would bet if this was a big bore build and put on a dyno, that arraignment would certainly produce lower numbers than without. Maybe not significant, but something. Not criticizing the work, just commenting on how something as simple as the screen can alter the air flow and the hose that appears to be in the air stream. I too would suggest drilling an additional hole and relocating the right side directly out and connecting the two behind the back plate. It would also remove the uphill tube.
Those are/were my thoughts as well.The screen alone will slow the air flow. It is his bike and I'm not going to criticize it either.

Stock configuration has the rear tube running uphill also, albeit not quite as much. I do believe that the oil/mist coming out of the breather will be sufficiently pushed uphill for that short distance.
This has been a work in progress, started last year with a simple extension of the tubes more deeply into the throat of the intake.
I should be able to get back on the bike tomorrow and try this latest version out.
I am not out to squeeze every last hp or ft.lb or toque out of this bike. If it runs properly and does not seem to be running rich, and my seat of the pants dyno is satisfied I'll likely keep this setup, though I may remove the screen if the clamps show no signs of moving, which they didn't last year in a previous iteration.
Alternative is to put the breather tubes back on and let the oily air enter the intake. I don't want to do that. So long as I don't see a quick buildup of oil in the can or a noticeable downgrade in performance due to air turbulence in the filter body I'll be happy with the mod.

Nothing in the catch can when I checked it this morning. Hoses showed a little condensation. Clamps remained in place. Maybe removing oil and leaving it a half qt. low on the stick has made the difference and will prevent as much blowby as I was seeing after the 1K service and prior to the Stage 1 and 2 install.
