Hi does any scrambler owners know what PSI the fuel system operates at cheers Bryan U.K.
Cheers for the info Derek I'm going to be running my 20k miles scrambler on twin 39.5mm flat slides dellortos and a straight through exhuast by sc .i can buy a malpassi fuel pressure regulator to carb conversion gizmo which reduces the pump pressure down to 1.5 psi and sends the rest of the fuel back to the tank cheers Bryan.I can't say for definite but most other Ducati FI systems run at 3 Bars.
Would gravity feed not be an option or are the carbs going to be too high ?Cheers for the info Derek I'm going to be running my 20k miles scrambler on twin 39.5mm flat slides dellortos and a straight through exhuast by sc .i can buy a malpassi fuel pressure regulator to carb conversion gizmo which reduces the pump pressure down to 1.5 psi and sends the rest of the fuel back to the tank cheers Bryan.
I would like to keep the stock tank with the built in fuel pump so that the fuel warning light and trip counter still work and the fuel pump will also act as a stop cock when its not runningWould gravity feed not be an option or are the carbs going to be too high ?
How are you going to make the sparks?... I want to get rid of dash and all the lectric wizzardry,...
I did not know that but I don't want to get too involved in what goes on in the tank I still have to find out what pressure the curbs run best at and I think a manual adjustable relieve valve hidine under the tank is easyer plus I might need to swop back to injection for MOTsI wondered why you wanted to know what pressure the injection ran at when you are switching to carbs!
The pressure regulator is on the return side. If you bypass the regulator inside the tank you will have a similar setup to the old carbed 900ss, where the pump provides a flow but little pressure.
It will cope with up too 5bar and it looks like a old diaframed fuel pump from the 60s 70s and about the same sizeWill your Malossi regulator cope with 3 bar of pump pressure?
Ideally with contact breakers !!How are you going to make the sparks?
It would be easy to leave the ECU in place but not use the injection part of it but that would require the dash to enable the immobiliser function.
An MOT in England has a lot to do with who you know but one thing is for Shure no loud pipes so you just put stock back on for the testI dunno...forgot you guys have yearly MOT. Not confident the carbs will pass 2015 onwards emissions regs. Don't let me put a dampner on it tho.
That said, you guys would have the same issue with a Termi map so what would I know....
I had forgotten about the MyECU option, although I don't think I'd like go there myself.Ideally with contact breakers !!
But seriously using existing trigger and "normal" amplifier box (myecu one?) far easier that current conundrum with dash.
Still trying to find a way to run EFI without speedo/immo/ bloody flashing ABS light etc etc. Removing the ABS pump would be nice too
Has to be possible, just need to find the right geek.
Even if I ran dash and ECU with carbs (as OP ) I have a feeling dash will have a proper hissy fit cos EFI not EFIing, maybe just another warning light, maybe a system meltdown.
Hopefully Bryan lets us know soon.
Why does MOT care if carbs or EFI ? Last MOT I got was before EFI was common (actually only on 851's then !)
Can only be CO2 test, jets'll fix that
No emissions tests for bikes here though, yet. I don't know what you get in England thoughAn MOT in England has a lot to do with who you know but one thing is for Shure no loud pipes so you just put stock back on for the test
It's the same test as Scotland.An MOT in England has a lot to do with who you know but one thing is for Shure no loud pipes so you just put stock back on for the test
