Don't you just hate it when that happens?

Well played!

I have been looking at these for a while - but they always needed a return fuel line which was going to be a big job for my setup. This version doesn't need a return line. It looks as if it ought to be fairly simple to do - and hopefully it'll be easier to set up than any of the wanky carbs you can get for these (or the one they came with). Hopefully will have the by-product of not belching tons of unburnt fuel when the engine is cold and generally being greener. Might even save a bit of fuel.

That looks a good solution. Presumably it will handle ethanol better, too....

I can't see a lambda sensor there so how does it know how much fuel to chuck in there?

Probably 'open-loop' so it's set up just like jetting a carb. One of my FI bikes is the same.

If that's the case I think I'd be spending a bit more on kit with a standalone ECU. I'm pretty sure then you'd make the savings in fuel, especially with prices as they are? There used to be an Engine Masters show on Youtube with 2 of the blokes from Roadkill. I'm sure they covered the carb to EFI kits.

It does have an O2 sensor - with a clever bracket you only need to drill a hole for.

Sniper EFI Software free to download which allows for realtime tuning

Took the bad water pump off the good engine so I can put the good one from the bad engine on there.

The impellers don't half look different - I've never had an issue with cooling and the heater's pretty effective, so hopefully it won't start to be an issue now.

One looks like a budget version, does the one with the solid metal impeller have replaceable seals and bearings?
