Looking for the Raptor part number, and do you get less range or the same with it? thanks

Miles per tank, same.
Miles on reserve, less.
Dave has a post that lays it out, but I don't know where.

Cheap ones, online, have skinny tubes.
Buying local, no surprises.

Yep, always best. I dunno if you HAVE to, but it's a good idea.

I don't shut mine off every time I stop to rest/eat/sight see - but you should be shutting it off when you park the bike for the night.

Shutting it off does several things:

1)  In case the carb needle/seat doesn't seal completely, it keeps you from filling up your air box or crankcase with a couple of gallons of gasoline.

2)  When your bike is parked, the fuel in the float bowl will slowly evaporate though the vents.  As the fuel evaporates the portions of the fuel that evaporate the quickest leave first.....and the ethanol stays behind.  Eventually the level in the float bowl will drop and the needle/seat will open and allow some fuel to flow in.  After this process is repeated several times the stuff in your float bowl is mostly ethanol and the gummy part of the fuel.  The ethanol is corrosive to aluminum and will attract moisture.....and it will be necessary that you take you carb apart to fix the damage.  (If you turn your petcock off....there will be far less fuel in the float bowl to allow the carb to be gummed up).

I have a routine on my way home at the end of each day.  When I turn the corner at the cross roads about a mile from my house I reach down and turn the petcock off.  By the time I reach my driveway and turn in the carb is out of fuel and the bike stops......I then coast down my driveway and put my bike away with a nearly empty carb.  That way I have reduced the chances of carb corrosion or jet clogging.    

It can, and has, on several bikes
if it does, what you'll get is a bike that runs fine at lower RPM, but won't sustain higher RPM, s no highway riding
This is why we say always get the real deal, it's only, what, $5 diference or so?

How long have you been running it? See any downside?
Extended high RPM, extended high power needs, like climbing a long hill, the fuel use might be more than the flow rate through the petcock.
Lower fuel level in the tank means less head pressure to drive the gas through the skinny tubing. And then there is the carb. What size tubing fits IT?
I'm still confused about why people insist on buying online when they could walk in a store and lay the part on the desk and look at the replacement and verify it is what they want. It supports the local economy, no waiting or paying for shipping, and even when they
Ship for Free
you paid for shipping, in the price of whatever you bought.
Now, IF shipping is free AND the part costs fifteen dollars And it came from China, just how much of that price is actually what it cost to make it?
Sure, they cut corners. Look at the cost of the tubing. The difference in the cost of the tubing, multiplied by the number they make,  and IF there's a problem, where do you go? For all I know the quality of the casting is less than the factory part.
Wanna see me go off for real? Walk into a store, get a clerk, ask them questions, try on what they have in stock, then go buy it online.

You might also check that your fuel cap is venting properly....a vacuum in the fuel tank could also cause those symptoms.

Also the carb has a small screen filter at the top of the seat for the float needle.  If that is partially clogged it could restrict fuel flow.  You have to drop the float bowl, remove the float and needle, and then you can remove the screw and pull out the seat to access the filter....I can't imagine trying to do this with the carb still on the bike.

OK, I now have the correct part on my bike. Maybe it is just me, but I can tell the difference.
