SOURCE: 2007 650 yamaha vstar popping through the rear cylinder exhaust

First off did you buy it new? Second has it gone through its break in tune up yet?Did you do the re jeting? My guess is it was re jeted wrong & neeeds to be re jeted again or could also need more air(upgraded air kit) or a tfi or power comand fuel mod.My bike also poped untill I did the air & fuel upgrades & them upgrades will also give you a much needed house power needed for this rig.


Bring it to a shop & have it looked at.......


Good luck

SOURCE: honda 1986 vf400f nc13 engine front two cylingers not firing help

If the spark appears to be weak only for the two front cylinders, then I would suggest checking the electrical connections for the ignition coils.
If the spark for the other two cylinders looks the same (yellow), then I'd suggest checking the compression on the non-functioning cylinders. A compression reading of 140~160PSI is what you're looking for. Low compression indicates internal engine damage - or could be from something relatively simple - like insufficient valve tappet clearance.

If the bike has been sitting for a long period of time, it could be that the carburetors are plugged up with fuel varnish. This can cause some cylinders to not run. A complete carb disassembly and clean-out will be needed.

I cant quite figure out which spacers you are refering to. The only thing I can think to suggest is the exhaust schematic on bikebandit.com. If I knew for sure I could try to look at my bike but there's no telling what previous owners could have done. Sorry. I'd really like to help.

SOURCE: Runs on back cylinder but front cylinder pops a little when idlin

This particular model uses a BS36ss carb for the # 1carb or back as you are calling it. there is an input and output as a pass through to the second carb intergrated into the fuel delivery system of the # 1 carb. the # 1 carb draws fuel from this port also. check for obstructions at this point where the 2 carbs intersect and in the transfer line to the front carb remember this is a neg. pressure regulated fuel system so any leaks at carb 2 (Front Carb) or Balance Tubes Between cylinders and it wont function . vacuum is the key

I have a 1994 olds with a 3.1 and I have oil coming from the egr valve anything wrong with it????


The egr valve would usually connect the intake and the exhaust manifolds together, often via internal drillings in the cylinder head. An egr valve can be automatic and self-contained or operated by electric or vacuum via the the engine management. Feeding a percentage of exhaust gas into into the intake under certain conditions reduces dangerous exhaust emissions.

Sometimes with diesel engines the pipes, ports and the valve itself become blocked with oily carbon and it isn't unusual to find some free oil in there too but that doesn't usually happen with petrol engines.

I am not sure why you have oil in your car egr valve but I would guess there is a problem needing further investigation.

Where is the 2.5 d4d erg valve mounted on the engine


In internal combustion engines,exhaust gas recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in petrol/gasoline and diesel engines.EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders. Thers a hose going down the rear of the engine to the exhaust pipe. It recirculates the portion of the gasses coming out of the engine by putting in back into the intake manifold, where the engine can burn it again, thereby reducing the emissions. The EGR valve is located in the engine compartment (underneath the hood). Usually on the side with the air intake manifold attatched to the side frame rail

Exhaust sensor


Well you realy need a spical tool to remove O2 sensors because a wire is comeing out of the top of it and you can't put a regular socket on it with out damageing the wire . Although you don't say what kind of vehicle or what year it is . I will give you a basic overveiw . Older vehicles have 1 O2 sensor its on the Y pipe comeing off a rear cylinder . Newer vehicles have 4 or more sensors all in the exhaust system 2 in the Y pipes 1 on each side and 1 in front of the catiylic convoter and 1 after the cat The way it normaly works is bank sensor 1 is in the Y pipe and its closest to the front of the vehicle . Then bank 2 sensor 2 is on the other side of the Ypipe if you have a V engine . But bank 1 sensor 3 is in front of the cat and called a down stream and the final sensor is behind the cat and sences the out put of emissions going out the exhaust system . The tool is cheap you can get a kit for 20 bucks or so with 3 or 4 differant kinds of scockets however you may need a breaker bar to loosen then witch is a long bar for leverage . Just make sure what code you have and witch one is bad first and try checking the connections to them first . They don't usely go bad unless there something else wrong with the vehicle

There is a tube on the "side" rear of the engine that leads to the front. Into this tube are loosely place saller tubes coming from the engine. This tube appears to have snapped. Would this...


the tubes i think your talking about have to do with emissions that supply fresh air to the exhaust for those cylinders when required.if they break off you will get an exhaust noise which is what your hearing.there are only 2 ways to fix this.one is to repair/replace the damaged pipe or remove the pipes and plug the system off.be aware if you do the last it will fail an emissions test and have to be replaced to pass anyways.

On my pipes one side is hot and the other is cold


Check the pipe right where they come out of the heads. It depends on what type of exhaust system you have on your Road King. If the stock exhaust is on the bike, the rear cylinder exhaust is directed to both mufflers. With the exhaust from the front and part of the exhaust from the rear cylinders going to the right side muffler, it gets more exhaust than the left side and runs hotter. Like I said, check the temp of the exhaust pipes at the cylinder heads. If one of them is cold, that cylinder is not firing. As long as both of the pipes are hot there, you're fine. Just ride the bike and have fun.

Ride Safe.

How to change an exhaust on a ford focus 1.6 16 v


there are rubber mounting underneath the car, remove there.

follow the exhaust pipe to the engine, loosening any bolts and nuts holding the exhaust in place.

the exhaust pipe meets the exhaust manifold close to the engine. loosen it there and replace,

the part remaining on the engine (also a much thicker pipe than the pipe) is the exhaust manifold. this must the loosened at the engine itself. normally two nuts per cylinder and your car being 4 cylinder its 8 nuts.

There nuts can be dreadfully tight though, it gets hot there so the expansion and cooling of of the studs and nuts tend to make them tighter over time

What is the function of lambda sond? it's good or bad ?it's about what?


First used in February of 1977 on Volvo B21 four cylinder engines, the Lambda-Sond system was an emissions reduction system which used three key components working together:-


1) Lambda Sensor. An exhaust gas composition sensor to monitor chemical composition of engine exhaust gases; especially NOx (oxides of nitrogen) which feeds data to the engine control system. In simple terms it's an oxygen sensor positioned in the exhaust pipe before the catalytic converter.


2) A feedback loop providing information to the engine control computer that enabled more precise control of the fuel injection system.


3) A catalytic converter.

This system greatly reduced exhaust emissions while allowing much better performance and fuel economy. It proved to be a key to restoring the performance lost by the addition of emission controls on vehicles. It was the forerunner to modern electronic engine management systems that eventually appeared as similar systems on all road-going vehicles.

So it's a very, very, good thing and like all similar systems requires periodic maintenance and repair, usually the parts which fail are the lambda sensor and/or the catalytic converter.

I hope that my speedy and free reply has met your requirements, if so then please take a brief moment to rate my answer.

I went to autozone for a o2 sensor and they told me that "before the catalist or after" what does that mean?


Most newer vehicles have more than one O2 sensor on the exhaust pipe for the computer to take more readings for better emission control .

Before the catalytic converter is the exhaust manifold to the cat. There should be one O2 sensor there in that part of the line.

After the catalytic converter is the cat to the end of the exhaust pipe. There should be one just right between the cat and the muffler.

A four cylinder engine should have two O2 sensors. Six cylinder engine should have three O2 sensors. With the six cylinder there would be two O2 sensor before the catalytic converter and just one after the catalytic converter.

Bank is referring to a collection of cylinders. I.E the curb side cylinders. Sensor 2 mean cylinder 2 in bank 2. It is not a O2 sensor. The computer is noticing a fault in a middle cylinder...check spark plugs for abnormal or premature damage
