SOURCE: 1000s breather

by the frame but from looking at old posts it seems it should be mounted into the spigot on the engine casing? Also my bike has K&N's so obviuosly the old airfilter box has been removed. Thus the vent to atmoshere which used to run through this box now simply runs down to the back of the engine. ... so my 2nd question is this... should this vent to atmosphere have a valve on it? ,The breather system should have one valve in it and it should be AFTER the breather box on the line that vents to atmosphere. THis is to stop wet cold air entering the breather box and mixing with hot oily air and making mayonaise or aioli. Guzzi's earlier attempts put two valves between the breather box and crankcase - stupid. If you're bike has the old breather box and not the breather box in the frame like the later square fins then remove them - one is hidden in the supply pipe in the breather box - remove with hammer and screwdriver. This will also stop the engine pumping oil up the return line and out of the engine. Any 4 cylinder automotive spring loaded PCV valve will do pretty well. You can improve the efficiency of the breather box by lightly stuffing it with stainless steel wool or such. If the rings are good and the sump level is right it will not drip oil IME.,,,

SOURCE: my 05 fatboy seems to run pretty good but it tops out at 90mph

yes,there is more you can do.Like a big bore kit,matched with some higher rpm cams, but remember this is a softail with the balancer motor so it will always steal some power away from the wheel.

if you buy a Power Commander from a company called Dynojet then yes you can adjust the system yourself however even if you get a power commander my suggestion is to take the bike to a dealership that has a Dynomometer and have the bike tuned on the Dyno that way you know exactly what your fuel is doing and you dont lean the mixture out to much

Sherco 300 SEF-R spilling oil out breather pipe


Hi, Manfred oil level readings are taken when the engine has reached normal operating temperature and the usual suspects are:
1. Overfilled oil tank dipstick reading should at or below full.
2. If the sight glass is full you are running to much oil. 3. Excessive blowby caused by worn out piston rings.
4. Piston rings never properly seated.
5. Faulty breather valve or system.
6. Pinched or clogged breather line/hose.
7. Clogged or failed oil filter.
8. Contaminated oil dirt-rust-water etc.
9. Excessive oil foaming.
10. Wrong oil type not designed for your bike.

2003 harley davidson full dresser back fires or pops sound on the left side pipe when i let go the the gas handle at around 2000rpms it all started when i had new cams put in


Popping sound at the exhaust is usually due to a very lean setting which causes unburnt fuel to burn late in the exhaust pipe and happens when you are going at a high rpm with a closed throttle making it even leaner. My bike had the same problem and most Harleys are factory tuned lean which is very bad as the engine runs hot. After putting free flow Rhinehart pipes like i did, it became worst so i installed the Vance & Hines fuelpak and now my bike runs so silent and cooler. A great difference from before.

I have a 2012 harley and im getting oil blowing into my air breather how do i find wear its leaking


The oil breather/separation system ends up in the induction pipe throat and the oil mist that does not get eliminated in the breather process is then sucked into the induction system and burnt n the engine. If your oil level is too high or if the breather system is defective this will cause excessive oil to end up in the air cleaner area. If the tubes etc that direct the oil into the induction system throat are missing or defective this would also add to or cause an excessive oil in the breather area problem.

Have doherty air fillter fitted but have bin blowing out oil so shop fitted lines to take oil but pipes just go under frame so placed pipes in can that i strapt to frame is this ok


I'm assuming that your are talking about the crankcase breathers in the heads. As long as the breathers are not blocked and the engine can expel the excess crankcase pressure, you're fine.

Good Luck

05 fxdwg back fire when I let off the throttle


Bike fire through the pipes at deceleration is usually caused by a leak or leaks in the exhaust system, usually at a muffler joint, etc., sometimes at the exhaust port itself. To fix, locate the suspected joint and tighten the associated clamp. If this does not cure the issue, you may have an over fueling issue. Is the bike fuel injected?

I have a 2008 Harley Crossbones with Rinehart Crossover exhaust. It just isn't loud enough for me. I am used to no baffles in my carb bikes. How do I get more sound. Cut baffles?


Check after market pipe makers like Fubar or Kirker.Don't mess with baffles it aint worth the hassle of re-setting the computer.New duel pipes with straight pipe design will come with the new mixture settings.

Smoke comming out of breather pipe at front of engine


The breather pipe is at the back? What exactly is it that is smoking? It is normal for the breather pipe to smoke, it is releasing crank case pressure. Is the bike otherwise running ok? if yes then dont worry
