Good day to you all!
My GS is close to 50K miles and I've had several strange issue with it, such as:
- Feeling that the fuel/air mix is amiss, like when you have 4 cylinders and one doesn't run but here it's a 2 cylinder obviously.
- Rough idle and when using 95 petrol pingin until 3K rpm, disappears from 2.5K rpm onwards with 98 petrol.
- Vibrations that come and go depending on rpm, not really knowing what could cause it.
So, I was about to start the throttle body sync (did the valves spot on, oil and filters before a few days ago, plus four new spark plugs, went for a ride to get the engine warm and fuzzy) when I noticed that the right-hand side injector was missing its metal bracket to hold it into position, as per the picture:
Here comes the left hand-side for comparison:
Could this be the cause of the bike's erratic behaviour?
With a variable fuel pressure in the fuel lines depending on throttle opening, I wonder if it could move the injector in its craddle and affect the alignement of the injector's shooting angle. As there seem to be two toric joints to ensure no fuel leaks, those still allow for the injector to have some freeplay.
I took both of them out, and switched sides when I replaced them. I went for a ride, I think the bike ran better, but it could have been my imagination too.
How to spot dirty or failing injectors?
Is this missing braket that important?
Thank you!
