I do not have a tach, and do not need one. You can pretty much tell if you are lugging or not. Heck, I ride my EVO through the park at 18 mph in 3rd. Motor is just above idle, but not working at all. On the other hand, if you are going to hit the throttle, you better shift down a gear or two. If the motor is not pulling, you are not lugging it. When I go on the on ramp to the interstate, I rev out pretty good in each gear, hitting 5th at around 60. It just depends on how you are riding at the time. If you are one of those guys that rolls on the throttle real fast, you need to be in a lower gear. If you roll in on real easy, you can shift much faster. Thats my 2 cents. You do have to have a feel for what the motor is doing.
If I took everything off my bike I didn't need I wouldn't be left with much...sometime you chit just because you want it not because you need it

Lugging at 1800 RPMs?
Get real.
I find it hard to believe, as much torque as a Harley has, someone is lugging at 1800.
Some people think if the engine is bogging down it is lugging. It's not. Lugging is when the engine is jerking, you feel it as a front to rear jerking motion.

You badly need to really do some research on the topic of lugging. LOL
You likely are doing it often and don't even have a clue, because your description of it is way off.
hint: You are indeed lugging WAY before you reach the point u described above! He he! When it gets to jerking, you have maxed out the lugging beyond drivability.

If I am paying attention to the speedo, on my '04 heritage, I shift up from 1st at 10+mph, 2nd @ 20+, 3rd @ 30+, 4th @ 40+ and 5th @ 45+, just don't like the sound below those speeds. But, I have a friend that outweighs me considerably (I'm @ 220#) and he shifts up at much lower speeds than I do and has never had a problem other than with the carb and a cam bearing, he rides a 2000 heritage.
From my aircraft mechanicing days, I do know that at low operating temperature, the pistons are loose in the jugs, if not, they would be too tight at running temps and the engine would sieze. Then at running temps, the expansion is such that the pistons will barely move side to side. With liquid cooled engines, this is not a problem due to having constant temperature control.
Just my 2 cents.
But, these things do sound best when accelerating under load don't they?
