I was talking to a tech rep at the S&S booth, he said the best cam for a bagger, in his opinion, was the 510; and they like to run above 3k RPM. you can actually damage the motor if you lug it.

 

Duh, you can damage any engine if you lug it. 3K is not too low for a twin cam but depending on the cam profile it may not make great power at the lower end.

 

75 mph in 6th gear is right at 3000 rpm. I am sure they did that for a reason.

 

I have just 5 speeds, but 3k equals 75mph for me too

 

On our Heritage, we've probably put 50% or so of the 47k miles riding 55-60mph in sixth.
Another 30% of the time, we ride in the country, Usually in 4th.. between 35 -40 mph

She just purrs at 2,000 rpms. and has for 7yrs and 47K.

 

I have a 07 and 2k is lugging in it.

 

Only time mine sees 2,000 RPM'S is when running thru the gears. Mine likes 2,700-3,200 RPM'S the best. I always heard Harleys like higher revs.

 

I think they run good from 2500 to 3000 rpm's but at 3 I'm ready to shift to the next gear if it's there.

 

I always keep my RPM in the 3000 to 3500 range, always have....They run better up there.

 

it doesnt lug at 2k rpm if you get a proper map loaded.
