Re: 5vy r1 not starting

I would empty the tank completely and replace the fuel filter if itβs been slitting for a while. The ethanol in modern fuel turns to brown sludge.

+1 easy start is not goodpolar wrote: βSun Mar 01, 2020 6:57 pmYeah lay off the easy start but you could always try beautain.Snakeboots01 wrote:To be honest that is one thing I havent done I have looked at the fuel in a cup and looked good but I will put some fresh in and try that. I would have thought it would try fire with some easy start down the butterfly, but I only squirted a touch in just to try it, I dont think it does them any good that stuff. I've got a few things to try now, fuel check the wiring for the clocks, I will update tomorrow how I get on

I agree, the white connector can cause all sorts of issues and plenty of head scratching. Always worth a look.newsh wrote: βFri Feb 28, 2020 2:47 pmTake a good look at the big white connector behind the LH fairing. This takes all the signals from ECU to clocks. As well as the lighting and backup voltage to the trip counter).Snakeboots01 wrote:Thanks guys. I think I will concentrate on other parts not the alarm no wires are cut I cant find any plugs close to them to plug into.
I have a spark and have lifted the tank taken off the fuel pipe flicked the key and fuel comes out at some pressure not exact on the pressure but it squirts out. I can strip the fuel pump and check the gauze filter see if its blocked.
The er-4 on the dash is getting to me need to see what these clocks do when I get them.
Does the immobiliser kill the injectors because that would answer a lot of questions just thought I would see the red light on the dash flash. The red light does nothing at all key in or out
These plugs are a known source of problems on all the R1s, on my 5VY I had to bypass the connector to get good lights and clean to re-establish the trip backup. Had similar issues on 4XVs.
Glad you have it sorted now mateSnakeboots01 wrote: βTue Mar 17, 2020 4:50 pm Managed to get the bike running turns out it was a us ecu I have bought so swapped the plug leads round and it fired straight up, wish the guy had mentioned that but never mind. Found a dodgy thread on one of the plugs now so the head is off all fixed just need to put it back together, thanks for all the comments and ideas.
So, US spec ECU fires the plugs in a different order? Or have I misunderstood?Snakeboots01 wrote:Managed to get the bike running turns out it was a us ecu I have bought so swapped the plug leads round and it fired straight up, wish the guy had mentioned that but never mind.

FFS. Any idea why?Snakeboots01 wrote:Sorry for the late reply yes the cylinders are the other way around from US to EU.
US cylinder 4 3 2 1
EU cylinder 1 2 3 4
That might be the wrong way round but its opposite
So a EU bike with a US ecu the plug leads are the wrong way around so it will not start just backfire
Yeah because they're septic tanks , they drive on the wrong side of the road and want to go to war . . . . .
