My bike has a hesitation at approx 10% throttle. Its intermiting , does it cold or hot but not all the time. Feels like someone shuts the ignition off for a split second then back on.It does this a few times then goes away. It seems to have started since i accidentally left the key on and the battery died but that shouldn,t have really done anything since the run switch was off. bad Coil? TPS sensor? Anyone ever have this thanks

Malinda's Dyna did.  It was a bone stock 96".  She replaced the muffs with 1.75" Rush's and a SE/AC with a SERT.  That took care of it.  I don't know why it started since it didn't have it when she first got the bike.  It had a bit of a flat spot there but that's typical for the dunb ass gearing that HD uses.  Why what she did fixed it I have no idea, but it did.

Since everyone on these sites seems to do these changes ASAP, maybe they all do it and none of us ever realized it.  Wink

Ride Safe,

The new bike had some "dead spots" in the power band & one was coming through about 2,400 rpms or so.  Not every time or all the time but enough to piss me off.  Not sure of throttle position then - believe it was more than 10% but it was annoying as hell.  Went away after the tune/breather/pipes.  My 07 Ultra was similar but it was much more of a dog before the tune/b/p.  So was my 02 RK but it was hesitation at higher rpm.

Yours could be something else - mine was just the crappy factory tune, which is actually a de-tune.

I'm gonna stay tuned about de-tune updates in this thread while  listening to other tunes.

Mine's good at anywhere above idle. I'm not sure if mines like others and I simply don't recognize it or if mines different. I'd side with the latter since, afterall, I'm the Jester Whisperer.

My wife's carbed sporter is notoriously reluctant on throttle response until its good and warm. What a PIA but it feels so old school and is a fun change of pace.

Bad gas? I'd bring it back to Andrew. You had Rosa tune it right? Let him check it out for ya. It's prolly a tuning adjustment. Wink
