Quote from: Hossamania on September 16, 2024, 05:22:26 AMWhich tuner are you using? Was it modified as exhaust and air filters were changed? What and when was the last time something (exhaust, etc.) was changed? How soon after that did the problem start?
When was the last time the intake, throttle body had a good cleaning? Are your heads still venting into the intake, or modified to vent to atmosphere? If still vented to the intake, that can introduce oil mist over time, which needs to be cleaned out of the throttle body. Cleaning is a good idea even if vented to atmosphere. A good intake/carb cleaner sprayed in all the orifices, throat, linkage will help with better running, and possibly lean conditions caused by dirty intake.

Thank you again for the response Hossamania.


I am using the Fuelmoto Mini EFI tuner. I has been updated since I changes the pipes and air cleaner. But I did message them again to make sure it is the right update. 

The problem didn't start untill over a month after the new exhaust was put on and over 2,500 miles later. In that time everything seemed fine.

Besides replacing the rocker top gaskets the top end of the motor has never been gone through or modified. 

I've run the intake and carb cleaner through twice now and plan to do it once more this weekend. After I went through the process last night I rode her for about 20 miles at various speeds and it appears that the sounds is almost gone. 

Thank you for all of the advice so far and any further advice!

I know at one point Ford's was 1 qt/500 miles was acceptable.

I used to be able to find that info however it seems to have been removed from all sources on the net. Good luck

We have an updated camshaft comparator. The Feuling 543 from rigidthumper above. Also four cams from Area 51 Racing. Three for TC motors, 588, 590, 664, and one for M8 motors their 465 cam.

Didn't HD have a "1 qt/1000 miles" is a non warranty issue?

I also don't think 1 litre for every 250 kms is anywhere near normal or acceptable.

In that case I miscalculated. It's more than that. And it sure is annoying. When I'm back on my PC, I'll see where I stuffed up.

Quote from: Hossamania on Today at 06:15:13 AMI just did a quick conversion, your oil use converts to about 1/3rd of a quart to 2500 miles. I don't find that to be outrageous, if a little annoying. That puts it at about a quart between oil changes if you go 7500 miles, still not outrageous, almost normal.
Does it do it all the time, or just certain conditions, like a lot of back road lazy riding and also high speed long distance travel?

Sometimes Google is helpful. LINK
