Fuel Pump regulators on 950"S

I'm having serious issues with my 950 flooding out while pounding the whoops, I thought I was going to be stranded in the middle of nowhere yesterday with a deed battery.
I have double checked the float levels,Im also running a facet pump and really don't know where to turn.
Im planning on racing this bike here soon, but at this point it would be a epic fauil.
Ive heard the addition of a fuel pump regulator might help, but I cant find any info on that.
Is there anyone here that has had the same issue and came up with a solution?
Thanks in advance

I do understand why some would look to another pump such as the facet. I carry a spare pump in case it fails out on the trail. Its not that hard to replace. Then you can buy the points for $35 to fix the one that failed, and still have a spare. If you replace with stock, you will make it thru the race and then some. It was designed for the bike.

I replaced the points once on the original and then replaced it with the dr.bean points replacement and haven't had an issue with the last several thousand i've put on it since.

No worries about flooding because it only replaces the points that go bad and retains the original pump

You probably already know this, but Holley makes a regulator that could be set to give you the right pressure. I was having a lot of trouble dialing in my bike and thought that I was getting irregular pressure. Turned out not to be the case. Good thing. That Holley regulator ain't cheap, and you really need a pressure gauge to set it properly. In addition, it's not small, so you'd have to find a place for it. You could move the battery and mount it low. I didn't want to do that. You also could mount it behind the airbox, but that puts gas over a coil, near hot exhaust, and just under your family jewels.

My experience has been that the Facet does hold pressure pretty well. I would guess you're dealing with something else. My suggestion would be that you PM Pyndon. He's rallied his 950 a lot, and I'm sure he could help you sort your fueling situation.

Get an adjustable fuel regulator. The 3-6 psi model from NAPA is about $35, if I remember right. It's set to 3 psi in the box. This works.

Napa's Gold fuel filter is good also, 20 micron and $6.

Lower the floats 1/2 mm below stock, this helps also.

Oddly enough, mine was doing that (bone stock) and it turned out to be the side stand. I lubed it and cleaned the sensors and it went aWay completely. I recently put the switch delete on so I no longer have to think about it.

I lowered the floats when I first got the bike, I noticed the flooding issue after the Facet install.
It sounds like you had the same issue and the regulator cured it?
All the regs I have seen are huge. Thanks

Have you checked the needle and seat? if you have correct float level but a bad needle and seat it will let fuel by even when the floats have it closed.

Also should check your carb venting. If you havent replaced the "Y" in the air box with individual lines I would recommend that highly. Made a world of difference on mine.

Mr. Gasket pump

I had exactly the same problem when I switched to the Facet fuel pump.

The solution is well recognized, and worked perfectly for me. Find a Mr. Gasket fuel pressure regulator, which will be $40 or $50. Set the fuel pressure at 1.5 to 2 pounds not more than 2.

You can mount the regulator between the pump and the carburetor, just underneath the tank, by adding a loop of fuel line that circles around under the tank at the side of the engine.

Good luck with it.

Thanks so much. Lots of great knowledge and experience here on ADV

If you have a stock pump the Mr Bean kit is the way to go it replaces the points with an optical switch.

Really the best solution.

Thats what i did

I thought I should come back to this and let you know what I found. Its really something I should have noticed.

Things continued to get worse and the bike became unridable
upon some thought and thinking there is no way just the FP was causing this issue, I started poking around. Not really seeing anything out of the ordinary until my focus went to the choke cable, I noticed that although the lever went back to the closed position the cable was bound up, looking into the steering stem I noticed a spot that looked like it was smashed, replaced the Choke cable and now this bike handles big hits with ease, even threw in a nice double jump just to make sure. Man I love this 950!! I should have known better.

Good to hear, it got resolved.

Still think the stock pump with mr bean kit is the best solution out there in my opinion.
