What size Jets does it have ? Pilots and Main Jets ?. You could be over-jetted or the coils & caps are wanning (not as punchy as before)
I’ll be completely honest, I have no idea what size Jets. Spark seems good.
It is worth opening the float bowls and taking a look and let us know, and this will be a sure thing for you too, it may idle fine but as the road speeds go up, it may bog down more as it has too much fuel or otherwise try to get a meter out and test your coils with actual figures.
Ignition Cap Resistance (under 50,000 ohms) without the coil attached, just the cap. But i wouldn’t trust OEM caps to save my life anyway, so best to use NGK caps.
Ignition Coil Resistance (without the cap attached)
– Primary Ohms and
– Secondary Ohms
It could save a lot of guess work.
