crankcase breather

[card16969]

has anybody completely blocked off the crank case breather into the air box while doing the airbox mod and replaced the hose with a crank case breather filter instead? Also was there any bennefit?

Yes I did.It idles smoother because you arent pulling in bad oily air from the crank case.That can foul out the throttle bodies as well.You will smell a little oil at idle but cruising, wont know the difference.

I think mine is just blocked off... I should probably address this

Ok, my '02 Busa engine and mapping are stock. Should I consider adding a crankcase breather ?

It has a crank case breather already it’s in the back side of engine and breaths to the air box.

Billet plate and ditched the hose for a mini filter

Should the breather be upgraded for stock Busa ?

If so, there are block-off plates, 1 or 2 ports. What's best for stock Busa ?

It's a preference and looks nice. The stocker is same ugly and has a funnel looking hump going upward with said tube attached. The low profile ones clean up the area and free up some space which could be useful in the future. Oh ur right if one just blocks it off the oil starts bubbling from pressure not good.

I can get the filter at most auto parts store right ?

The site I ordered from doesn't include the filter.

Steel braided fuel lines?

check out amazon under crank breather case filter. the size 10mm,12mm13mm is how long the conecting tube is on bottom of filter not the size of the actual filter. $6-15 not bad.

 

[bussassin417]

conecting tube is on bottom of filter

What size does a Gen I Busa use ?

They are listed in mm sizes but all they mean is the conecting tube that the securing clamp goes on is whatever mm's long or tall. If you look further some list the measurments of the filter it's self. Just saying don't get confused with how they list them as 9mm or 12mm filters its bull & has nothing to do with the filter size. all the same size just type in crank breather case filter & they come up. Think Busa 1 has right idea with the cone shaped one though for better breathablity.

 

[bussassin417]

better breathablity.

Great. Thanks again. I learn so much, from so many. This forum is awesome !!!

Steel braided fuel lines?

Nitrous lines are steel braided..... My fuel lines aren’t steel braided they made of some other type of material. Forget the name but Knecum recommended them. Just as durable and long lasting but a little more flexible and easier to deal with. I tried to bulletproof this sumbich as much as possible when I got the engine built

If the bike is stock, leave the stock breather on it. The aftermarket plates don't have the weir system in them and are much more likely to push oil out during high power situations.

Dont think this is true. There are several high power bikes running the lower profile plates.
