Hello everyone, few months ago I had my valve shims checked, replaced intake rubbers and fuel filter on my 1997 Vmax. All worked well for like 150km and then I could feel the loss of power. It behaved like there is not enough fuel, stumbling at 3000-4000rpm. Right-back cylinder now does not want to work in any rpm range. Checked carbs and they are clean and shiny. Checked spark and it is good and strong. If I close the needle jet completely on that cylinder, engine does not stumble. Checked compression on cold engine and all 4 cylinders are close and within specs. Fuel tank was coated with epoxy paint so it is clean. I am out of ideas Do you have some?
