Coils on multi-cylinder bikes usually have one coil for 2 cylinders.

SOURCE: 1979 suski 750,bike runs on 2 left side cylinders,

Hi and welcome to FixYa,

With the indulgence of craigjamesbt...

A few additional ideas to consider:

  • it would be an electrical/ignition issue if 1 & 4 or 2 & 3 will not fire but not 3 & 4;
  • almost always, raw fuel on exhaust indicates a flooded engine. A flooded engine would most likely be a carb issue;
  • best way to determine if it is an engine concern is to do a compression test;
  • a way to test the right carb pair is to deliberately starve them of fuel by temporarily plugging/blocking the inlet port/seat with rubber similar in appearance as to those used for glue gun, not installing the needle and float. Assemble the carb and install. Start the bike and use/spray carb cleaner on the right side carb. Note if 3 & 4 will fire even intermittently.
Would appreciate a postback on results/updates on any developments.

Good luck and thank you for using FixYa.

Stock size for the slow jet is 35. Some guys put in 38's to make them less prone to getting plugged. I would say that you still have gunk in the slow jets. Also turn the pilot screws out 2 1/4turns. If the exhaust pops and you have no exhaust or vacuum leaks turn the pilot screws in 1/4 turn at a time till it goes away.

Did you change the plugs and the air filter? How about checking and or replacing the vacuum lines?

You might try a full bottle of Techron fuel system cleaner in a tank of gas. It may clear the problem up.

I had to clean the jets on my 1999 I/S twice and it's not a fun job.

Hope this helps.

SOURCE: exhaust pipe comes out white smoke when start bike on side stand

Continuous or just for the 5-10 seconds.
If continuous you may have oil seeping past your pistons oil rings or valve guides oil seals.
Check your spark plug see if they are fouled badly (covered heavily and oily) or just covered by oil and sooth lightly.
If 5-10 sec it is normal as the engine is heating up there are normally a little oil seeping past the seals.

Rough idle and smells like gas when driven

When checking for Vacuum leaks, did you use a water spray bottle on seams and vacuum lines and EGR pod?(engine running)

Check for air leaks in exhaust before O2 sensors. O2 thinks its running lean from air leak in exhaust header and enrichens fuel charge.

Fuel injectors dirty, not closing tight. Switch injectors to other bank and see if Error Code moves to relocated injectors.

Bad spark plugs, check if you have fuel runners in your intake.

Extreme heat coming from the exhaust between seat and body from my 2013 canAm spider RT limited

There are several things you can do to reduce heat on a Can-Am Spyder.

1- Remove the plastic 'Splash Panels' under the frame below the motor. These were added NOT to keep water and debris off the motor, but to reduce noise to pass EPA noise standards. Removing these panels will not hurt anything and allows hot air to flow out and cool air to flow into the engine compartment.

2- Wrap the exhaust with exhaust wrap (found at any auto parts store). Start as far back on the 2 exhaust pipes as possible wrapping towards the front. Wrap all the way to the head on each pipe. 1" exhaust wrap goes around bends better, 2" takes less time. Overlap each wrap by 1/2 of the width of the material.

3- Adding a fuel management system (Two-Brothers Juice Box Pro or Power Commander system) will allow you to increase the fuel mixture to ideal levels. The Spyder runs very lean from the factory creating additional heat.

Runs rough unless you choke while driving,leaks gas out of 1 of the carbs on rt. side

That is one of the best signs that the carbs need rebuilding and cleaning. On a Valkyrie there are SIX carbs. Take it to someone who knows what they are doing. When it's done Hang on it will run like new.

Where are the oxygen sensors on 2002 villager? I believe they is one before and one after catalytic converter. Is that correct.

correct, called upstream and downstream. look at the exhaust pipe running under you car only two electronic parts(wires) should be plugged in to it. one is right on the exhaust manifold/header(header comes out of the cylinder head) and one right after the catalytic converter. if you have any engine besides the 4 cyl such as a v6 you might have more than two. the easy way to change it is to spray it with wd-40 or equivalent penetrant, cut the wires and use a breaker bar and socket of the right size, that is assuming you everything ready to get the job done.

1997 Volvo 960 6 cyl - Started running rough when I got on the freeway. Up until then it had been great. Very Smooth. I have a check engine light that is flashing. The car idles rough up to about 1900...

Check wiring harness to fuel injectors where it runs through intake manifold - these chafe through and cause injectors to stay on or off. Also check engine grounds. 2 at back of head near firewall and one at drivers side engine mount (almost impossible to see)

Engine starts, runs rough (like cylinder missing), after a minute will run smooth a few seconds, then back to rough idle. new gas, new oil, gas filter seems clear. What else to check?

Establish which is the 'lazy' cylinder (touch the exhaust pipe header with a WET finger). There will be a marked difference in temperature. Change the plug on the 'lazy' side. If no better, check for a good spark - with engine running on the good cylinder, connect the other plug lead to a spare plug and grund the plug body. A weak/internittant spark will be readily apparant.

If there is a spark problem, replace the coil on the dud side. If not, check for equal compresion on both cylinders.
