bike is a 2008 nightster!
i just baught the bike, it has an aftermarket air intake

the white smokes comes out when then engine is really hot! there is also oil spitting out...i did chek the oil level and its below full
i think those are the stock breathers

anyone know what this could be and if its dangerous...read multiple theads but dosent seem to be concluent!

i still need to install my v/h fuel pack would this have anything to do with??

solutions?

here are some pics:

 

I can't tell if the breathers on the heads have been capped off or just open.
If they have been left open and your normally running the oil tank at full that might be the problem, you also should get those tempuratures down if your seeing smoke, the fuel pack should help that and maybe a change to synthetic oil if your using dino oil now.

 

Almost looks like the stock breather bolts. Could someone have cheaped out and just left them there instead of getting a breather kit or breather bolts that are less prone to spitting out oil?

 

if it was mine, i would:

1. install your fuel management system (your bike will run cooler once you enrichen it a bit)
2. lower that oil level to a bit above half way up the dipstick- mine is never higher
3. put in a horseshoe breather

and i did just those things on mine too!

 

White smoke sounds like fuel to me get that fuel pack off there and use the S.E. tuner

 

its not white white smoke but more like just smoke!

and i dont understand why it spits out oil and smokes when the bike is really hot!

is there an easy fix other than the horsershoe breather kit?

 

It could be just oil mist. OTOH, your cylinder or cylinders could be shot and is having excessive pressure to the crankcase. Can you do a compression test? How many miles?

If we are correct and that is the OEM bolt, it could be that the thing was NOT built to contain the oil without the ham can.

Define "easy". Either that or the breather bolts. I don't see how it can get easier than that other than to turn everything back to stock.

 

I'd ditch the fuelpak but I wouldn't install a SE Pro Super Tuner unless I was sure that it works right. Remember, the bike ECM is now married to the SEPST for life and there is NO such thing as a "No Fault Divorce". Don't install anything until you figured everything else out otherwise you end up chasing all sorts of variables.

 

Pick up a pair of Outlaw Breather Bolts from DK Custom, problem solved.

 

Is there a pinhole for a vent or a large hole? I can't remember exactly but I believe it is a pinhole. Would it be easy to to a compression test to make sure the gasses are not passing the rings and building up pressure in the crankcase?
