How do you test for a leak on a Harley, on cars it is simple cause you see the black carbon streaks arround the area and usualy can hear it.

 

Sorry for all of the questions, just that Harleys are new to me and I cannot afford a service manual yet, I have been trying to find an electronic one online but no one is sharing these.

 

For the intake leak,you can test like for a car.

Get some aerosol carb cleaner and spray around the gasket areas while it is running.If it inhales the cleaner thru a leak (bad gasket) ,the engine will speed up.

 

I just checked all the bolts and such then i took it apart and replaced all the rubbers, as far as tuning, i have an older bike with an old fuel management and i plugged in the laptop and richened it up a little bit and the popping went away so i am not sure if it was the intake or the tuning, but i think that both helped. Mine still pops a little bit when it is cold but when it warms up it stops. I need to upgrade my fuel management pack then i could adjust more. I also have been told if i get it on a Dino i could get it allot closer.

 

Those thunderheaders are decent sounding and performing pipes...don't trash them till you get her tuned. Then listen and decide.

Not sure what fuelmanagment device you have, but if it's a PCIII, go to the dynojet site and see if they have a free map for your bike and intake exhaust combo.

 

I honestly have no idea if there is a fuel manager on this bike or not, how can I tell or where would I look, like I said I dont know the past on this bike at all.

 

PCIII should be behind the right side cover. You could also check under the seat for anything extra connected to the battery in case you have some other type device. If you don't find anything there you probably don't have one.

 

Yeah, you really need to look to determine what you got going on there.....also check to see if previous owner upgraded air cleaner.....if you have performance pipes and air cleaner, but no upgraded fuel managment, then pray previous owner had dealer flash the computer to compensate.

If you don't know what to look for, it's gonna cost you a few bucks to have a dealer do it for you.....No one except dealer can read if stock ecu has been flashed, but experienced wrenches can at least determine what you got going with exhaust and air cleaner.

 

Dude, take those ugly, awful sounding mufflers off and send them to me before they make your bike tip over!!!

 

most likley one of 2 things leaking exhuast or inproper tuning,a fuel managment device is a must.
