banshee Banshee w/ 7mm Stroker

[04BANSHEE7mmSTROKER]

On my 04 Banshee (with a 7mm stroker) What would be the "safe zone" for rpm's (where I shouldn't go below or above), what would be the absolute max rpm's I could hit (safely and unsafely), and, at about what rpm's would I start and end powerband? Remember, it has a 7mm stroker kit. Thank you for your help.

Ported? Carbs? Pipes?

all effect powerband

Safe zone?

0-12k rpm

No such thing. There is a friend zone tho

The safest RPM for any motor is 0. If you don't run it, you won't have issues.

And remember guys, it has a 7mm stroker.

Safe zone? Is that like a women shelter, or like a first date 3rd base swing?

Common sense says don't go below 0 rpm or above 12K rpm

 

I'm assuming he is talking about mean piston speed which increases a stroke increases.

From the 2 stroke tuners handbook, the normal max MPS is around 4000 ft/minute

MPS=.166*stroke (inches)*RPM   which puts the normal max rpm for a +7mm around 10,500.

BUT, Not very many people get on here talking about snapping rods and over that RPM you are in over-rev and should shift anyways.

Basically don't be a dumbass and rev it to 12K for 5 minutes at a time.

I'm going with zero rpm for safe. Seems most applicable to me.

Pipes, porting, compression, timing, and stroke all play a factor in what the RPM will be.  Just let it eat and make sure you're feeding it enough fuel.
