449/511 Breather hose mod

I got them because they were lighter than brass and were perfect for my application ! No hose clamps right there anyways a 5/8 bit fits perfect in the cap , drilled it deep as I could then shaved the rib off , finished the hole with a dremel , tapped it , lubed the threads with JB weld and tightened.

Found some cool free flowing check valves for $50, I'm going to test with no check valves, if blow by issues occur then might try running a bottle neck up the exaust line to pressure up the catch can a little so it dumps back to the engine better, will run larger hose to the airbox so less vertical gas flow velocity .

Question:

Let's say you can figure out a way to run 1200-1400 CC's of oil in the 449/511, would you think the additional oil capacity could also make the oil run much cooler?

More oil slapping around is more oil transferring heat into the cases and less friction building heat also less room for casing gasses to circulate so they exit the breather better. Yes

Your camera messed up!

Going underground. Hahaha

The big 103mm pumpkin smashing bore needs some breathing room !

Actually if you read back a few, maybe twelve pages or so you will see that I am currently running 1400cc's. Besides running cooler, the engine has less vibration, makes less klunky noises and is generally quieter.

So what do we have to trade for the secret? I can spare a kidney...

Will see if you likey , maybe some money ha ha

Function first then looks ! lol

Bah! You are definitely not vane enough to ride motard...or not as narcissistic as me! I am only creating a dual exhaust for looks (and hope it does not have negative effect on power.

Will do Kelly. We are actually rushing the breather hole mod right now, which gives us a little more time to make fine tuning on the breather bottle. I can tell you that the breather bottle has been designed to work with all exhaust systems including O2 sensors and the Akropovic power bomb which should make Caiman extremely happy. You will be able to open the breather bottle in order to clean dirt and debris from it too.

Also, we have brand new Ty-designed billet shifter levers for the 449's coming, those will be available through Hall's I believe.

Got to have it !

Baahaaa haa !

so it's going on the right side , is there a filter in it and how would the dirt get into it, also does it send back oil to the engine automatic or do you have to manually drain it ?

Right side yes. Depending on what the vent hole is connected to will determine the extent of the debris. Oil will continuously drain back to the engine or it will be allowed to flow upward into the drain back line.
