Bike has a stage 1 w/ download & hooker true dual pipes. It has what I call a cough or slite spit at the injection/ air filter sect. at low speeds,, at high speeds its great. Would a leaky intake/ exhuast gaskets cause this, like it would on a carburated bike?

Ive been looking at the dynojet power vision tuner, any suggestions would help! Thanks, Troy

 

A leak might cause that, yes. Have the injectors been replaced from the 8* to 25* injectors yet?

 

Hey Dawg,I have a 2006 Ultra with Stage 1 and SuperTrapp and it isn't showing any of the other guy's problems but I'm interested in the reason why you're asking if the injectors have been replaced from the 8 to 25.Is there a reason they should be replaced?Thanks

 

Some of the 06s had 8 degree injectors. They have been known to cause " drive ability issues". Mine had 8 degree injectors. Never really had a problem but I changed them to the replacement 25 degree injectors anyway.

 

The 8 degree injectors were problematic as skydude stated. Some folks' bikes had been known to cough and die in the middle of traffic, thus causing a safety issue. The remedy was to change them out to 25 degree injectors that HD came out with.

 

Would you suggest an injectors swap anyway even if my '06 hasn't been showing the problem?Would you have part #s.Thanks

Heres a link to a PDF of the service bulletin that covers this problem. It has pictures of the two injectors and the part numbers.

 

I would swap them out anyway.

 

IS there a way to tell which one you have in the bike? That is thru a visual inspection - part stamp on the injector?

I've a 2006 UCEG. No issues at all with the stage 1 on my bike. BUT wondering IF I'd notice an improvement switching IF the bike has the OEM 8's.

???

THANKS!
