ENGINE HESITATES WHEN ACCELERATING. HELP!!

[bwmatt1]

Lately I have been experiencing a miss, or hesitation when I turn the throttle about halfway. It idles fine, it cruises fine, and it's fine under full throttle. But at half throttle it jerks and misses and acts like its totally misfiring. Rpms are usually in the 2500-3000 range. I really noticed it while cruising in colorado. I couldn't just easily accelerate going up hills, I had to give it full throttle. Just changed the plugs...no change. Any ideas? TPS? Injectors? Valves?

How many miles?

Have you checked your fuel pick-up screen? Had a similar problem with a C109 Boulevard and it ended up being that screen. Changed it and all good. Couldn’t hurt to eliminate that for starters.

Had a similar problem on my '09, problem went away after 2 tanks of fuel. Bothersome, as I was on rte 2 in N. Dakota I think at the time.......

From the Voyager 1700 shop manual page 199, section 3-97: "Fuel Filter Cleaning
○The fuel filter [A] is built into the pump and cannot be
cleaned or checked.
If the fuel filter is suspected of clogging or being damaged,
replace it with the fuel pump as a set."

just read your post, Did you try higher octane gasoline?

I have the same issue, 2016 Voyager and it is also between 2,500 and 3,000 RPMs. I currently have 5,000 miles on it but it started around 600 miles.
Only when it is hot, not all the time and being winter I didn't have the issue when I rode over the last 5 months. I also live in Colorado and I have taken it to the shop but it was only in the 50's so they couldn't duplicate it.

I have put fuel treatment in (suggested by the shop) around 1,000 and did it several times and I run the highest grade you can buy 91 (it is = 93 at lower altitudes). Have been riding this winter and it still can happen but not like when it is hot. In the mid 70's this week and I got a little of but I wasn't' running hard.

If anyone out there has a solution or when it starts again for me in the coming months I will be sure to post an update.

Just bought one and noticed this also. Not to bad running around the local highways, but a trip to Tucson and running back up I-10 the engine was running really rough.

75-80 on the interstate going up some steep hills, RPMs 2500.

This bike does not like low RPMs.

After the local shop told me the bike was running normal, and since I'm almost at the break-in mileage, I took it out on a local highway today and kept the RPMs at 3000.

It ran much better.

I'll most likely be doing Ivans ECU flash to make this bike run like it should.
