Its about damn time. lol We expect a full 3 page report.

I'm still going to put that system on my hawk. It will more than likely be after the summer when i'll have more time to mess with it.

We're foaming at the mouth like a rabid dog, so get on with it already!!!

Lucas@Air_Lift · 05-10-2017, 07:29 PM

So, I pit the plate on it, go to start it and nothing. Cranks no fire. Pulled the plug wire and have good spark. Pull the return line... no fuel with the pump running. AFTER ALL THIS THE PUMP DIED!!! I have not touched it in weeks, and it worked great when I parked it. I am only mostly disappointed right now.

Lucas@Air_Lift · 05-10-2017, 07:30 PM

I messaged the seller of the kit and am awaiting a response. They want $80 plus shipping for a new one

**JerryHawk250** · 05-10-2017, 08:32 PM

That sucks. That's not the report we wanted to hear. Check on ebay, you might find a replacement.

Lucas@Air_Lift · 05-10-2017, 09:39 PM

So, who thinks a Grom fuel tank will bolt on to a vader? I think i may just get one and try it.

prismways · 05-11-2017, 12:00 AM

that would be interesting. All I know is the Vader tank is pretty damn small. It's kinda silly. The SSR Icebear's is almost twice as large.

I don't know what PSI you need but maybe get something like this http://www.ebay.com/itm/Motorcycle-E...JYCZNs&vxp=mtr

Lucas@Air_Lift · 05-11-2017, 10:22 AM

So I just overnighted a pump and regulator. I ordered an inline pump for a Moto Guzzi, and a universal adjustable pressure regulator. I WILL ride my bike this weekend damnit!!

**JerryHawk250** · 05-11-2017, 10:25 AM

That looks like a more reliable pump too

What PSI are you running? 40-45 psi?

Lucas@Air_Lift · 05-11-2017, 11:12 AM

The pump included with the MotoEFI kit runs 300kpa, or 43.5psi. I plan on leaving the vacuum reference port on the regulator open to run a steady 43.5psi as the included pump would do.

And I agree, this pump looks much more robust, and also they are readily available in the US. Guess I found one weak point of the kit... hopefully it is the only one!

Lucas...sweet

So you diagnosed/verified with the presence of voltage at the pump but no go I suppose? You gotta love those victories.

Correct. You can hear the pump run, it just produces no fuel pressure.

daChurchPcGuy · 05-11-2017, 08:18 PM

Oh, that's just great, I ordered one of these!

I have another pump if this one fails

Lucas@Air_Lift · 05-11-2017, 09:10 PM

Well.. this is weird. I got a new adjustable rear shock with a stiffer spring for the bike that I installed tonight. For the hell of it, I tapped the pump with a rachet a few time... and it built pressure and fired up!! So I finally took it for its first street ride. I stayed close to home just in case the pump died again. The tune needs work, but I got her up to 46mph! Still going to replace the pump this weekend just to be safe.
