Running out of gas when idling for a short distance, have to pump the bulb to prime it again several times in a couple 100 yd idle. Changed out the fuel hose with a new hose and same issue. Runs fine at high speed. 2018 Eyra, 250 XS
dpny62 I chased this problem for several years on my 2017 model. Replaced the on-demand valve, (warranty) no change. Replaced the pulse pump (warranty), no change. Changed out the bulb (warranty), no change. New filter on VST, no change.
Finally I cut a couple of inches of the tubing going into and out of the bulb and re-installed with two (2) radial head zip ties in opposing directions before and behind the bulb, pulled as tight as they would go without breaking. All I can say is, after that I never had that problem again.
A minute vacuum leak in the hose will result in loss of fuel flow at idle but not so much when running on plane. Worth a try.
