pdwestman Yes, I will suggest that it is a vacuum issue.

I my opinion, you need to take a 'Very Close LOOK' at the throttle slide DIAPHRAGM.
The won't rev over 4000 - 5000 rpm is my clue.
The tiniest pin hole will do exactly that, much less a sealing ring 'pinch'!

A replacement rubber is available, from Tucker Rocky/ Bikers Choice dealers, part # 482841.

shaoul So here's a new example of this issue. But first, I drained the float bowl per the the suggestion and found no debris. Riding today and had spent about 15 miles on highway at 70mph, then onto secondary roads doing 45 mph with frequent traffic signals. All of a sudden the bike begins to jerk and sputter. Plenty of gas in tank. What I noticed was that if the bike went over 4000 rpm the jerking and sputtering would start. At a stand still and in neutral the engine would rev above 5000 rpm without the symptom, but when in gear and moving can't get above 4000 rpm. I then stopped into a service station, got an ice tea and was contemplating the problem. Stopped contemplating and got back on the bike. The issue magically went away and I rode home without issue.
Could there be an issue with the vacuum in the carb? Any thoughts or similar experiences?

shaoul Sufficiently re oiled. Rainy Saturday coming up so plenty of time inspect the float bowl. Will give update next week.

pdwestman shaoul, I hope that you not only cleaned your air filter, but Re-Oiled it also?

And you both may need to clean your carburetors yet. But Simple, Cheap & Easy things first.

shaoul Serendipitous that this post was in the active area...saved me some searching.

Coverscout, we are "imagining" a similar issue. I experience the symptom primarily when I am riding for a period at a sustained speed and rpm. To a lesser extent at other times.

Paul, thank you for the hint to check the float bowl and re-route its' air vent hose. I'll do that.

I had cleaned the air filter, checked the gas tank vacuum, ensured fresh fuel and run some Seafoam through the system. I figured the next step was getting into the carb to give it a cleaning.

pdwestman I'll suggest that it is your imagination. But yet it might be possible.

With a clean clear vent hose attached to the carburetor float bowl drain nipple, drain carb into clean glass jar. Check for water or sediments. Then stand bike vertical & crank the starter button for a 3 count to flush the float bowl some more. If no water or debris is found, close the drain screw. Crank the bike for a 20 count to fill the float bowl, pull the choke on & it will probably fire instantly. Go Ride your bike!

If water or debris IS found, check the float bowl air vent hose on the upper Left of carb, to confirm attachment. If air vent hose runs up along RH frame rail & air box, move it go down along the shock spring.

Delayed throttle power

When I'm in third or fourth gear lately, I've had some instances where the throttle loses power like I'm running out of gas, but when I close and open it again, it seems back to normal. I'm wondering if there is a problem, or am I just being paranoid?

Disconnected/reconnected fuel lines 500 miles ago when I installed crash bars.
