Central Maryland | So I was coming off of a nice 50 mile ride into work this morning; and was on the last stretch of the highway. Coming out of a construction zone, I was accelerating failry briskly and shifted into 6th gear. All of a sudden, she start surging and bucking... almost felt like either the clutch or drive belt was slipping. Did not have it at that high of a rpm.... I let up on the throttle and reapplied thrust; did the same thing and after letting up one more time; she smoothed out.
Got about 5K now on the oil and was planning on changing it this weekend anyway.
Anyone ever experienced behaviour such as what I experienced?

New Bohemia, VA | One, from your post I don't know; where you live, what the year of the bike is (scratch this, I see it in your subject now...), how many miles on the bike, what mod's you've done, and you're oil has nothing to do with it, IMHO. So, let me guess, bad gas, bad fuel pump (I've been there), water on the spark plugs, bad spark plugs, bad brain box, bad which a-ma-gigger... Maybe someone with a crystal ball can answer you, or you can give us more detail. Either way, I hope you get it running right, if it ain't a brain box fart and it cleared itself up. Good day...

Central Maryland | Well, maybe I don't want you to know where I live..... :-)
But I'm just north of you, up in central Maryland, got 9351 miles on the bike, no mods (completely stock) it's got fresh fuel (daily) and I am just asking if anyone else has experienced this when getting into 6th gear during a hard roll on. Am thinking the engine is telling me it wants new oil at this point... but you think some other possibilities. Bad fuel pump; if that was the case... it would do it all of the time...?
I'll go ahead and update my signature since others have indicated in the past (to others) that they get all hot and horny when they can't tell where someone is from, or what kinda sled they got :-)

New Bohemia, VA | whoop-whoop! I've had mine hick-up once or twice, seemed like a fluke. The fuel pump, yeah, maybe all the time, but you best get the pressure checked. Not likely the culprit, but others have reported something similar and that is what it turned out to be. Mine, when it went, it went, full throttle, pushing into I-95 in front of a semi and then, wooooof, near total flame out, bucking like a stallion, and a KW grill in my rear view, not a good feeling... | |

That would be a BAD time for it to fail. Glad you stayed out of harms way. I'll see how it acts on the way home tonight.

Rhode Island | You said you were "accelerating failry briskly"; have you tried accelerating slowly to the same speed and see what happens? I had something similar on my Kingpin after filling up and it was crap gas.

Yes, I will play with the throttle on the way home today; and see if it replicates the same issue with slow rollons -vs- fast rollons.
Normally, I keep my gas treated with SeaFoam or Starbrite Ethanol treatments but have been riding my bike pretty frequently; so have really had not much of a concern treating the fuel since it is being consumed/refreshed almost daily.
Almost exclusively; I get my fuel from the same Shell station that has high consumer usage; so gas "should" be fresh at that station. But premium gas (which I run) isn't as heavily used as regular... | |

Central Maryland | Well...I could not reproduce the coughing and hacking of my Vision on the way home. Maybe it was a "brain fart" in the ECU or the fuel is suspect. Always keep a full tank (topped off always... habit from the Army) so condensation in the tank should not be happening on a large scale.
Guess I'll just have to wait for the next episode of it occurring. Hopefully not in front of an 18 wheeler... :-O | |

New Bohemia, VA | I forgot, there were two recalls for the '08s, for the switch, and the other for the main circuit breaker connection, I think. I only had the switch problem, but my point is check all of your connections. You don't have this as a known problem, but anything is possible. | |

Mt. Vernon, WASH. | If you buy gas at the same place all the time, find out what time they usually get their gas dump, then aviod buying fuel there for about 5-6 hours afterwards as the dump from the tanker stirs up all the dirt, sticks, dead critters, water, and gum wrappers in the tank that take sometimes hours to settle back out below the pump pickup feed which is usually 6 inches or so above the storage tanks bottom. And since your area just had some heavy duty weather, excessive rain could have been forced into the stations tanks.
The same compound used by station owners to 'stick' their tanks and check for water (usually a once a week chore, I know from decades ago as the night man at the station) so the owner can order fuel in the morning if needed, and some of it smeared onto a thin piece of wood and dipped into your tank will tell you if you've got water in your tank.
Once had an issue where the pumps wouldn't pickup fuel all the time or would pump gas then stop. The company fix-it guy found a dry cleaners plastic bag had been dropped in the tank by some smartass prankster overnight (doesn't take much to access the fill spout, about 3 minutes and a stout screwdriver) and it would get sucked up, cover the pickup and stop the gas flow. | |
