Engine bog has me boggled

The instructions say to set timing at full advance then lower the idle. Not sure if yours is the same as the Dyna S but here's the instructions.

A little though to your problem.
Have you check the F 1/4 and F 2/3 ignition timing, your 1/4 and 2/3 pic-ups could be out of the 180 degree distance. If necessary lose the nuts and adjust to the firing marks.

A pic from my DYNA III, the view angle is little relative.

yes, I checked my timing again. I set it with a timing light, 2500 rpm, full advance mark as per Dyan's document. Checked 1-4 and 2-3 both are good. Checked the firing at idle and it is good too. It was out a bit and helped the engine smooth out, especially on a start from stop in 1st gear.
I rechecked the advance mechanism and sal is good there too.

thanks for your input.

update:
thank you for all your support in this matter, I greatly appreciate it.

All this stuff I am doing to the bike is improving how it runs. The bog bug is not a severe now but still there. I can coax it up to 6500rpm but it hesitates and goes and hesitates and goes. If I roll on too much throttle, its bogs.

I put a relay system in for an independent power supply to the coils. I now have 12.8 at the coils, engine off. I had 11.6 before.
Synced the carbs.
Rechecked the timing.

There is a bug I am trying to figure out and that is I only get 13 volts to the battery when the engine is running. I tested the stator and I have 58 volts a/c at 3000rpm. But only 12.8 to 13 volts at the battery , even when I rev it up. If I got 14 volts, that may stop the coils from stumbling....?
I replaced the rectifier and regulator with a combo unit from Z1E, but that did not give me 14 volts. I checked the wiring and all looks good.
Not sure what is going on with the charging system.

I am going to go through the charging system troubleshooting document.

cheers,
Ron.

I read the whole thread and i think your main problem is a plugged carb part/port or tank vent.

I will check the tank cap vent.
I went through the carbs and they seem clear. I blew air through every hole.
I will open them up and search for the elusive bug.

thanks Scirocco.

It is a quick picture add
The pic shows not your carb type but a lot of carb internals could be suspect to your problem.
A good cleaning is the solution to most carb issues.
Some problems are located in a little detail!!!



I wish a good luck

update:

I am going through the crabs. All ports and jets are clear. I have the cleanest carbs in Canada.
My cam chain tensioner is shot I believe. Would this cause the bog?
Here's some cam tensioner pics.

Cheers,
Ron.

Your your cam chain timing looks good.

When I set the cam chain tension. I loosen off the cam chain tensioner and spin the motor over by the 17mm nut. The chain seems to slacken off in spots under the top cam roller guide. I think I should get an APE updated cam chain tensioner.

Is my cam chain stretched out in spots?

Also, When i cleaned the carbs I didn't find any blockage at all.

Never do a full turn over with an loosen cam chain tensioner!!!:S :S :S
The chain can slip over the cam gears = wrong timing = bent valves.
Only turn the crank some degrees clockwise to let the slack in the chain go to the tensioner side.

update:

I am ordering a new APE cam chain tensioner, my stock original is all over and done.
The chain had some slop in various areas as I rotated the engine after a cam chain tensioner adjustment. I removed the cam chain tensioner and used a steel lever to hold the inner cam tensioner with some pressure and rotated the engine with the starter. The chain was acting normal now with no slop. I think the new APE one should remedy that slop situation.

Would this shitty cam chain tensioner and the resulting slop in the chain be the cause of the bog issue?

I was hoping to find a plugged port/passage or defect on the carbs today but I just can't find any. All looks good, gaskets, seals, jets, ports,etc.
The carbs were really clean to begin with, Just needed a float setting done. I have rebuilt carbs before with good success.

cheers,
Ron.
