Fuel..?I’m reminded of what a two stroke lawn mower does after you’ve turned the fuel off and are waiting for it to run out and stop.They get to the point of a very low idle and give that bang…bang…bang bang….bang sort of stuttering beat to the firing, just before stopping.I cannot explain though, why a struggling fuel pump or supply issue, would only manifest at low demand settings.
Thanks for all the messages:Two points a) I am really interested in doing the timing light test, however i've never done it before. could you please explain me how or share any video so i can understand what to check? b) I remembered also when cutting the fuel of the outboard engines , however i think it was a different noise and kinda the whole engine failing at the same time maybe?I am waiting for the new fuel filter, i'll replace the other one in case there's something wrong there. Thanks Fede
I am really interested in doing the timing light test, however i've never done it before. could you please explain me how or share any video so i can understand what to check?
I am thinking if there is a stray or mis timed spark, you will see the erratic nature of the flash on the light, coinciding with the stagger in the beat.Are you getting excessive noise from your camchain ?Wondering if there’s a fluctuation in the cam timing at low rpm allowing the cam timing to jump around.Do the injectors take their commands from the cam position sensor ?Again, timing light….
Could you please tell me where is the cam position sensor located so I can check it? I am looking at the Workshop Manual but i am not able to find it. I'll check that is matching the specs.I understood perfectly with the attached video, just wondering:if bike idling rpms are around 1200. This means 20 revs per second and so 10 lights per second? Is it normal to appreciate the difference in the blinking just by eye? Maybe this is a silly question but gives an idea of my mechanical knowledgeThanks!Fede
Can i go for a ride with the inline light on?
I’m assured by Pete Roper that the bike has been at best poorly tuned and at worst, had it’s TB’s molested. He suggests that the stuttering that we witness, is actually spitting back through a badly ”adjusted” TB.Also the suggestion is that the plug cap or caps are maggoted.
If it looks the same as yours(TPS) I'd use it. It looked to be a curved adjustable slot for mounting. I thought they just had a hole.
maybe this photo explains better, looks like same thanksfede
