Question about 2005 Harley Davidson FLHTCUI Electra Glide Ultra Classic

6 Answers

Exhaust air stronger and warmer on side than the other.

I have Rush slip on's on my bike. The air being emitted from the right side exhaust (front cylinder) is warmer and stronger than the exhaust air being emitted from the left (rear cylinder). The right (front) slip on portion of the exhaust is much warmer to the touch than the left side (rear cylinder). I noticed in the left (rear) slipon a littleness wetness (black and oily) at the bottom rear of same. The bike seems to be running ok however. I have noticed some difference in the sound. Doesn't sound as strong and or as loud. Both spark plugs appear to have the same color with respect to firing. Neither plug is oily. The check engine light comes back on for a few seconds after start up then goes off and doesn't come on again until after the next start up. The year model is a 2007. The selector down below would not allow the choice of an 07. 2007 Harley Davidson Ultra Classic.

If the bike was running correctly BEFORE fitting the slip-ons, then you need to tune your motor to suit the slip-ons. If your model has Lambda sensors (these are units fitted into the downpipes about six inches from cylinder head) there is no need for tuning. If there is none, then a Power Commander is necessary as your model is fuel injected and there is no simple way to adjust the ECU. A Power Commander fits between the ECU and wiring loom and allows you to 'tune' the motor.

    Too much unwanted cool air entering the system will make one pop on decel, so you got to fix the leak.

Your head is most likely cracked and oil is probably leaking into the area where the head moves causing it to push oil out through the exhaust system and making the exhaust warmer and the oil is coming out. You will have to take this to the shop and let them see if your engine is rebuild-able which would be cheaper to fix because you will not have to get a whole new engine. If it is rebuild-able, they should be able to fix just the head that is broken. If it is not rebuild-able then you will have to get a whole new engine. If you keep driving it while it is broken, then white smoke will start to come out and it will then be nearly impossible to fix. And the leaking oil might ignite causing the engine to catch fire.

The reason for the air being warmer on one side than the other is because the mecanism that provide air intake in the system has the foam sealer worn out it need a new sealer if you remove the air duct under the hood you will see the problem on the cap that seal the air that goes in to the bike.

Hi, Mike timing on your bike is non-adjustable you may have an air leak in your exhaust system try using high temp silicone on your muffler joint if that does not help try installing some power cones at the front of the exhaust pipe and make sure your gasket and connection is tight for more information about your issue and valuable "FREE" downloads that you will need please visit the websites below, and for specific information or questions, please feel free to contact me at xlch@mail.com.

When my bike is running I get white smoke from the right side exhaust and the right side also blows harder than the left. What could this be?


IF you are running stock pipes (not "True Duals"), the right pipe exhaust ALL from the front cylinder, and SOME of the rear, and the left pipe only blows SOME of the rear alone.

The stock rear pipe splits, some going to the left pipe by itself, and the rest going to the right pipe WITH the exhaust from the front cylinder.

Now, white smoke usually indicates moisture.
Being a (non-VRod) Harley, that eliminates the liquid coolant, because there is none.

Next up that comes to mind is condensation.
BUT, this would burn off fairly quickly.

So is the white smoke only at first, or even when warmed up?
And if warmed up, is it actually coming OUT of the pipes, or OFF the pipes (like some oil burning)?

Well,...either someone has toyed with the baffles inside the mufflers,or they have rusted,and are starting to come apart. My reccomendation would be to buy a set of aftermarket slip-ons,or a full exhaust system.Good Luck!

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.

1997 Honda CBR 1100 XX. Bike builds idle slowly when cold . right side exhaust is forceful and hot while left side exhaust in minimal and warm only. Changed plugs and made no difference. Seems to idle...


Clay, you have a tiger by the tail. There are a lot of little parts to the carb system. I will try to assist you in the basics without carb removal. This may require a few replies back and forth. Start by turning off the gas then drain the carbs. Now turn on the gas and check to see that fuel flows into each carb. If gas starts flowing out of all the float bowls, now that the gas is back on, then all carbs are getting gas. To drain the carbs just remove the drain screw on the bottom of each carb float bowl. Two carbs have the drain screw on the left, two have it on the right side. Reply with what you find. tombones49_51.gif

Best sounding exhaust setup for XL883?


well....I would say the RUSH slip on's have a nice sound and give some performance increase. I put them on my XL883 and now it sounds like a harley instead of a moped. They have a nice deep sound to them and have a good bark to them when you get on it, but at cruise tame down to a nice rumble. You can put on the rush slip on's up to a 2" baffle with out needing to remap, now when you change your air cleaner too, a remap would be in order.
