Question Magnetti Morelli replacement options?

I have a 2001 95" Screamin' Eagle with the dreaded Magnetti-Morelli fuel injection. The bike runs well but... I have this annoying hesitation more than likely cause by a rich mixture that causes the bike to stutter when it is on a load (hills, full throttle) at about 2800-3100 rpm. I could probably just live with it, but it is getting to the point where I have to take it to the stealer at the beginning of the season for an "adjustment" which as always a $250+ deal.

I've seen the Zipper's Thundermax kit that swaps out the entire EFI at a cost of about $2500. I have heard of an S&S kit that swaps the CPU but keep the EFI, adding O2 sensors.

Does anybody have any info on running either? Or, on any other fix? I just dyno'd (free Dyno day at my stealer this past weekend) and I'm sitting at approx. 86 tq & 95 hp on the stock motor with a stage 1. I am hoping that I could push those numbers over 100 with an upgrade to my EFI. Is this a pipe dream?

THX!

Or you just swap it out for carb like i did with my '01 Ultra Classic. Cost about $800 to do myself and i wasnt super careful about saving money. WELL worth the investment.

Another vote for carb. Did it to my '01 RG and couldn't be happier. Carb conversion, cams and hydraulic tensioners was way less cost than any FI replacement/fix.

My issue with swapping to a carb is that I live at 7100' and ride the Rockies frequently taking me up to 13,000'. I also have 80* days and 30* nights. I don't know enough about a carb swap to know if these conditions would make it more aggravation than it'd be worth. Is there a "go to" install write-up you guys can point me to?

I did run across the Horsepower Inc. upgraded throttle body but I can't find anybody who has ran one. Harley also offers their upgraded ECM that has the ability to download the maps from the S&S VFI module. Haven't heard anybody running this either. Supposedly though, you can make it a wide band O2 sensor upgrade.

I can't be the first guy to want to upgrade. Any info on these to help me with the elimination process would be appreciated!

I did the Tmax replacement on my 01 RK with a 95" build, ported and polished heads, gear drive cams, oil pump, cam support plate, Baker 6 speed, etc. Bike ran great with auto tune on the Tmax. Was pushing 100/100 power. Got 32 MPG max but could run away from the newer bikes. There are only a few people that can tune that setup right to get the maximum performance. PM me if you want more details.

I just had the zippers T max for MM replacement installed couple of weeks ago,(Thanks Scott!!) WOW what a difference was worth every penny,feels like totally new bike,now my Hillside 98"build really rocks.Instant starting, rock solid idle,and the throttle response is right there.the canned map from zippers was right in the zone and i could feel the autotune learning with every ride and after a1000mi Im real happy,i had a power commander 3 on it and after 2 dynotunes $$$$ it still ran poorly. i would stay away from those piggyback set ups!,If you like the bike and are going to keep it i say go for it, you wont regret it.

I did the carb swap to my 01Rg,it was the best mod i could have done,now with that said you may want to check for the availability of the factory sub wiring harness that you will need,it may have been discontiued,its about a 3-4 hr conversion,now did you say what type of tuner you are running,i was running a early power commander,and it had a hiccup at about 2200 to 2500 rpm will cruising,but noy under power,i chased it for a couple yrs,then did the switch,i talked to the service manager of a shop in Indiana and he told me the hiccup was in the power commander,and that it could be removed.

2012 RG Vivid Black,contrast Anarchy wheels,SE air cleaner,cobra tuner,Thunderheader ,diamond cut heads and clys,Fueling Reaper 574 cams,this is just a starting point.
