I just noticed this on my last ride over lunch: While riding along, at low steady throttle, it seems like the gas to the engine is stopping and starting, as though I were closing the throttle all the way and then putting back at where I'm in fact keeping the throttle the whole time.
I just gassed the ride up this morning. It was almost empty and I filled it to the brim. Could it maybe be related to overfilling the tank? Could there be air in the line from running it all the way down?
It was a short ride, under 5 minutes, but the problem did seem to become less frequent as the engine warmed up.
Has anyone heard of anything like that? It's got 1070 miles on the odo, I changed the oil at 850, and I may have overfilled the oil a bit but haven't had any other problems with the bike so far.
Maybe it will go away on its own-- I'll try to pay attention on my ride home tonight and see if it goes away.

On the ride home it seemed totally normal, so maybe it was a one-time thing. I'd delete my post but I'm not sure how. Thanks for reading anyway.

Continuing paying attention. My 150 esp is at the dealer for warranty repair for a similar issue.
Re: Engine cuts off and on
Hasn't come up again in the past week, but I'll continue to watch out for it. When it happened the engine braking kicked in right away-- it was just as though I had put the throttle at zero, even though I was holding it at a constant level. I had thought maybe I was holding it right at some threshold, but it occurred at a few different throttle levels.
Sorry to hear you've been having similar issues. If you get to the bottom of it definitely let me know.

Re: Engine cuts off and on
I haven't had the problems like that on my pcx but when I had my Burgman it occurred quite often. What I ended up doing was put some fuel stabalizer in the tank. After that it straightened out until the next fill up. Sometimes I would get a good tank of gas and all would be well. What I found was that some stations allow the gas in their tanks to get low before refilling them so they end up with water in them. I don't know what the situation is there so just put either Seafoam in your tank or if your state mandates 10% ethanol mix, put something like Lucas Ethanol conditioner in your tank. It only takes a small amount so the bottle you buy will last for a long time.
