No, not something I was aiming to do on my bike! Someone said something on another thread that set off a chain of inquiry. The mad thought was "10 gazillion articles on carb to efi... I wonder if anyone's done it the other way?"
Crank sensors, yes... not thought of that. Inlet manifold... I would guess if the design was originally carb but converted that wouldn't be a problem (if old parts still available) but a freshly designed EFI bike would be a challenge I guess.
With regards to emissions I care only slightly about the environment as in, why not if you're not sacrificing much but I'll have a read up on Euro7 specs. I live just on the edge of London and my previous "eco as in free congestion charge" Euro 4 ultra-low-emissions diesel that we were all told to buy is now the bad man so not only did I have to start paying congestion charge a couple of years ago I now also have to pay another £12.50 to enter the ULEZ with it
I pretty much bought a motorbike on a whim and now it's saving me £22.50 + parking every trip into town! Funny how life turns out ____________________ Husqvarna Vitpilen 401, Yamaha XSR700, Honda Rebel, Yamaha DT175, Suzuki SV650 (loan) Fazer 600, Keeway Superlight 125, 50cc turd scooter |

Really.
In fairness, Enfield owners DO like to piss around with their exhausts, air filters, cams and compression ratios and the carbs are very well understood by now. They could also just plug in a dynatune box, but where's the fin in that.
One thing most people don't realise is most FI bikes have a fuel pump in the tank which may well need to be replaced with a tap (and definately if you're relying on an Amal needle valve to stop petrol pissing everywhere!). |
I read that as Anal...
Anyhoo, I suppose we're getting to the point where carb and EFI have diverged so much they're practically separate species.
Sad that treehuggers are killing off such classic tech. As a programmer I think I can fairly say, with some authority that I fecking hate computers and the all unnecessary automation. 9/10 times its a solution looking for a problem. ____________________ Husqvarna Vitpilen 401, Yamaha XSR700, Honda Rebel, Yamaha DT175, Suzuki SV650 (loan) Fazer 600, Keeway Superlight 125, 50cc turd scooter |

The only place I don't like to see EFI is on two strokes, as firstly it's pointless trying to clean up dirty stinking oil burning obsolete engines, and secondly I've never seen EFI make one run better. Things like overrun fuel cut of isn't friendly to two stroke engines and you therefore can't apply it in the same way. You also don't get time at high revs in the operating cycle for EFI to work, so a wet manifold (carb) is the way to go. |
Nah.
The ONY way to go for the future of 2t motors is EFI with forced induction and no fuel circulating around the crank. There is no need for strokers to burn oil.
However, there is no willingness to invest in the R&D to make this possible. The industry decided to shitcan strokers when they stopped using them in moto GP bikes.

Amen. For example why does my fucking central heating boiler have a bastarding computer in it? It has five input wires and three things to do. It can have the burner on or off and one or both pumps running. yes, there are a whole series of "AND" logic safety systems to stop it exploding but a simple relay would do it. And my washing machine.
Even a simple electronic project these days, they reach straight for a programmable system. Use an arduino where a 555chip and a handful of transistors would do. ____________________ “Rule one: Always stick around for one more drink. That's when things happen.
