My new FLHR Road King has the hiccups. I managed to put 38 miles on it
the other day. Bitter cold here in CT. I warmed it up by the book and took
off for the first of my break-in rides.

Within minutes after being underway, the engine started to miss or
hiccup. Often enough that I first thought I was running out of fuel. I
spoke to my wrench and was greeted with a knowing smile that he was
familiar with this. Seems the moco tunes the engines very lean to conform
with the EPA regs. and with the bitter cold here in Ct that was the reason
for the hiccups. He'll do a carb adjust when I finish break-in as well as put
on my custom exhaust. Still not sure what to put on.

Anyway, any opinions yes or no on the diagnosis.

He's right about the lean condition. Depending on temp and humidity, you may have had some carb icing. HD sells a Winter fuel additive. Get some of that and try it next time.

I'm no help to you other than to say that the same thing is happening on my '03 FLHR. Mine doesn't do it all the time...just on occasion. Even then it is just one hiccup, usually following deceleration and/or downshifiting, then rolling back into the throttle a little. This does seem to happen more on the colder days. I'm up to 300 miles on mine so far.

Bump the slow jet to a 46 and shim the needle. mine did the same thing stock and with slipons. had to shim a sportster needle and run a 48 slow. put a T-header on and perfect with 46 slow, 190 main, sportster needle slightly shimmed, stock spring and port hole drilled 7/64 bit (I believe). barely enlarged the port hole.

Rode today, again bitter cold here in Ct. Still hiccups, but not as much.
I just roll in a little more throttle when it does. I want to get my break-in
500 done and then deal with it. Managed to get over the 100 mark today.

Thanks for the help.

I'm wearing a Gerbing's heated vest and gloves. It hooks up direct to
battery and your off. Had about an hour of daylight left when I finished
installing it. I'm telling you it works great! I rode for an hour afterwards
but could have gone on and on. Decided to mention it as it keeps you
comfortable so you can enjoy the ride.

Hey mtucci,

Aren't you buried in snow up there like we are here??? Even if we weren't in snow _ss-hole-deep, the 2 inches of salt and sand on the road would be a death threat to all the chrome and aluminum.

mtmtrspt,

Nope on the salt, yes on the sand, it's here and there, you gotta watch
especially on the turns. Almost all the roads here are dry except for a
patch of wet occasionally. The bike is getting a bit dusty, but I want to
finish the damn break-in.

I'm feeling a long winter for all of us! Ride on!

Don't worry about it right now. When you change the exhuast, put on an SE breather kit and have the wrench do the usual jetting. The bike will feel like it has about 10 more ponies (because it will).

Shooter,

Thanks. Yeh, I agree. Will wait until I finish break-in and then deal with
the hiccups. Still looking at what type exhaust. My wrench says he knows
what I want, so I will leave the selection up to him. He's a good man,
been doing Harley service and repairs for some thirty yrs now, doesn't
sell the bikes. So, I will have him do carb adjust, etc and exhaust after
500.

At the rate I'm able to ride, it's going to be a while. It's either the cold or
the roads are too messy. Picked up a dusting yesterday, just enough to
keep me off the streets. Don't want to mess the bike up too much.

I noticed you have a 03 SE Road King, similiar situation? So, you did the
Screaming Eagle exhaust and engine mods??
