May be a stupid question but here it goes.When you bike is at idol and you crack the throttle wide real fast it stumbles for a secondlike it takes a second for the rpm to jump.When I twist the throttle fast but more gradual it is fine.Just like if I am in first coming to a stop and I hit the throttle real fast it hesitates just for a second as if the rpms were a bit to low and lugged for a second.thx

 

Does not happen on my 05 Ultra.

 

I was told my a friend of mine it may just be my throttle needs to be adjusted.So I would have a better throttle response.

 

Carb or EFI?

 

EFI

 

If it were a carb it sounds like a accelerator pump thing.
Since it is EFI the thing that does the same thing, to most extent, is the accelerator enrichment table. It's a SERT thing. Real easy to&nbsp\\;adjust if you have a SERT.
There are some other aftermarket tuners that can, I believe, fix this.
When you wing the troddle open there is a momentary lean condition, weather Carb or EFI, that has to be addressed. Engine goes, "GASP". not enough&nbsp\\;fuel.

 

Makes sense thanks for the info
