I just looked at the video, and I think your right. Looks very normal to me. What does it look like after a few hours running. That is what I would like to see.

OK, that makes sense. I didn't see the pictures. Should have read the whole post. I thought he might have added an "overdrive kit" .

Something doesn't add up here. You say you reached 62 MPH yet the Tachometer reads only 2000 RPM ? Do you have an "Overdrive Kit" installed ? I'm at 2400 RPM and only going 55 MPH in my Deuce ( or there about ) . I'm not trying to "bust your chops" but I am curious.

Did you ever take the boost pump plug out and check for debris ? You checked the pressure relief valve I see. I agree that your injectors might be the problem though. At 60 PSI you should have more then enough fuel to make power.

The release pressure is suppose to be 60 psi. So that bouncing around at 2400 RPM is really weird since it settles down to 60 psi again at 2600 RPM. I would take the plug off the boost pump and see if there is any debris in there.

It's hard for me to hear anymore. My left ear is almost totally deaf and the right one is trying to catch up ! I just heard a small pop-pop sound. Cannot tell where it is coming from though. I still say just put some additives in and run it extremely hard up some good hills. If that doesn't...

But that doesn't account for the "popping" sound out the exhaust. Something is not right there. I'm sure it is something simple but it needs to be checked out.

I agree with all the posts that mentioned using additives, but if that doesn't work then check the injectors like I said. Really cleaning your injectors is like changing your spark-plugs in a gasoline engine. It should be done on a regular basis. At the transit agency it was done every 50,000...

I was wondering about that statement too. Unless you have larger tires installed, going 70 mph at 2500 rpm is not physically possible with the gearing the deuce has. Do you have larger tires on your deuce ?

Yep, you probably have an injector sticking. So take them out and Pop-Test them all. Also when you do your next run with the truck try and load it down. Go up a good hill and really make the engine grunt. Or put some serious weight in the back and run it. This engine was made to be operated at...

That's normal for a truck that has set and idled for awhile. Take it out and run it hard. The rings need to reseat a bit.
