It won't *hurt* it...yet a lower rpm (3rd gear) if you are just cruising and don't really need instant power will help the engine to last longer. More rpm = more piston speed = more wear and tear on the cylinder walls and piston rings (not like our low compression low output motor really has to worry much about it...but still). Also you will probably use more gas in 2nd at 30mph than 3rd at 30mph.

In the end....its your bike and if you want to ride it that way do it!

The LS has such a strong engine that down-shifting on city roads is often optional once you get in 3rd. It won't hurt the engine to plonk along at low revs, just don't lug it low enough to get pinging. Riding around in 2nd @ 30mph is quite unnecessary with this tractor.

If you get surging or rough running at low revs, do the plastic spacer and airscrew mod.

No, it won't really hurt it, but I myself would prefer to be in 3rd or even 4th (on level road and depending on traffic).

Mine will even pull along on level road at 35 mph in 5th with a nice thumper tone to it (not lugging)...but mine isn't completely stock either.

Grunts from 2500 and revs like a two stroke to the 7500red line. Clive W

I just checked today (never paid attention before), and the Savage is doing right at 3500 RPMs at 30 MPH in 2nd gear.

The Savage also does 3500 RPMs at 50 MPH in 5th gear, so there really shouldn't be any problem with what you ask.

There is a difference between "can do" and "always do". Mine will do it, but of course to have decent acceleration and pull under load, I don't make a habit of it.
