Thumbs up fuel injection vs. carb

Is fuel injection really the way to go? I mean if you break down on the road your'e basically screwed. Any body go old school and put a carb back on their bike? I know there is that german outfit selling a wiring harness. If its done right it has got to be better than all that dyno time and ECM changes/ upgrades. All the heat issues will be gone that's for sure.
Never had any trouble with my evo with electronic ignition and carb.

Just thinking.

I like my fuelie. Push the button and ride off. And the tuning thing with my SEPST is far easier than changing jets on my carb bikes...more accurate too. Just my thoughts...YMMV...

...and I used to think my Sportster was heavy...

I'm on my 4th H-D since 01' with a combined total of almost 100k and haven't had a single FI issue yet. To me thats more then reliable enough.

My 08 was my first fuelie . I swore I wud never own one , kept the '88 TG for 20 years just to prove it to myself ..

Seems FI came out in 92 as a mid year intro , I have yet to hear of any real issues with it ..

I love it

I have owned several bikes of both types, and I really feel like FI is the way to go in this day and age. The biggest downside is the potential for an "off-on" feel to the throttle, which is more of a factor with race bikes than with our big TCs.
From a reliability standpoint, it is like most electronic things- terrible initially when manufacturers are learning how to make them, but essentially bulletproof once the tech is mature. FI (even in MCs) is pretty mature tech at this point, and I would not be excited to go back to carb. This is especially true since I ride all year, and carbs are a PAIN when it is real cold outside.
Cheers!

The thought of carbs brings me back to the CV carb on my 95 low rider....

Thinking about that POS gives me cold sweats, high blood pressure and a real short temper. I wouldn't go back to a carb, their far more trouble than FI.
Here in Colorado you can leave home at 4500 ft elevation and in 2 hours be near 11,000 ft. FI bikes compensate for thinner air and they run so much better than carbed bikes with changing altitudes.

I agree with the crowd on this one. Unless your racing, EFI is the way to go on a daily rider. I had over 40 K on my 96 TG and no problems with the EFI.

2010 FLTRX , Stage 1, 13" Madstad, Mono tubes, SuperShox, Heritage style bars. Alpine CDE-HD149BT,Soundstream Picasso Nano Series PN4.520 , 5X7 and 6.5 Infinity Kappa speakers
If I have to explain ,you wouldn't under stand anyway.

I put over 80,000 miles on my 04 carbed flhtc never a problem, I have put more miles then that on efi bikes over the years and never a problem. I rode my carbed bike in 17* temps and it fired right up. I rode my efi's in the same and they fired right up. One thing people don't realize is on newer carbed bikes ie at least 99 and newer thru 06 you were just as apt to fail from an electornic sensor as if you had efi. All are reliable. In 04 I had my pick and I chose carbed. In 2011 I did not have my pick but would have picked efi if there had been a choice. Just got back from Sturgis and most of the bikes you see are newer bikes and you know I did not see a single Harley broken down along the way or in Sturgis. I did see a guy pushing a honda tho.

Ya know Jeff...now that you mention it, I didn't see one either. I did see one EG Ultra on a flatbed being brought into BHHD, but it was obvious he had tangled with a large mammal.

Used to see quite a few bikes dead along the road...hmmm. Things that make you say hmmmm.

...and I used to think my Sportster was heavy...

I did have an issue with the ECM on my bike after riding in the rain for a week or so, the north east is so nice in the spring, I had water in the connector between the ECM Power commander. Took care of that and it runs fine now.
I am thinking of putting a Zippers Thundermax on anybody have this unit? I have always done all my own work on my bikes just don't like the thought of anyone working on it, just a stubborn old SOB I guess.+
