Do Any of You Big Guys Lug the Motor (i.e. knocking) During Take-Off?

Why? I see it repeated over and over but what exactly will lugging an engine do to it and why? and not because "some guy that really knows what he's talking about" told you.

Its the throttle by wire, theres a delay be it ever so slightly.
I just receieved a new 3 ton truck at work and it has the throttle by wire.
I have found that shifting gears with this set up is even different.
And I have to drive the truck in one aspect of or job at around 3 miles per hour with 3 men working off the back of the truck.
This set up stinks as at 3 mph the throttle is between sending a signal to apply fuel to not sending it so it makes it extremly hard to keep a steady speed, which is very important when men are working on the back of the truck.
Its the same on the bike, if you try to ride real slow you will have the same problem.
I would rather have a cable throttle any day.
So like its been said, you are going to have to roll on the throttle and get the rpms up then let out the clutch.
I have an 05 electra glide with cable throttle and I weigh at 300 lbs and the wife is close to 200 and have no problems like you describe.

I weigh in at just a tad under 300 lbs.
When taking off from a stop, I have to be careful to properly feather the clutch, otherwise the motor will lug and knock loudly. It seems that I need to rev the motor first, then let out the clutch. On most other bikes that I've had before, I could start to let out the clutch and then gas it. But it's backwards on this HD. Just an observation.

I've got you beat by some poundage and even two up on an '08 RK, no problem with lugging. In fact, '79 shovel, 80"er, no problems there, either. As far as the TBW lag, I've been ridin' 35 years and now I have TBW, I don't notice any lag at all ....... Me thinks you just need to get used to the new bike.

Just thought I'd provide an update... I installed the Screamin' Eagle Big Twin Compensator a few days ago, and the knock that I described in the OP is completely gone. So it was the compensator all along knocking, not the motor (thankfully).

Good way to know is when you pop the clutch and hear the tire squealing...It's much better than lugging the engine, LOL.
Seriously No...Like others said, "Just give it more gas, rev the engine up to an desired RPM range and engage the clutch as you're good to go".
