fi2000 question

[Idaho]

I have researched the threads on this site and have about decided to get an fi2000 for my 07 Nomad. It is surging at low speed and has a tendency to stall out when it is cold. Bike has 30,000 miles, stock debaffled exhaust and a K&N air filter. I do not want to change out the pipes but am thinking that the fi2000 will help with some of the other issues. Not really all that interested in turning the bike into a dragster. My question is will this unit help with the issues that I'm facing without changing the pipes. yeah, I'm cheap.

I would say "yes" that it would help with the stumbling and surging issues. I can't offer an opinion on the fi2000, but the TFI has cured these problems for others. Me included.

i have the fi2000 on my 08 and yes it will eliminate the issues
you are asking about.

It depends on what is causing your surging and stalling. You may have a vacuum leak. Also, you might want to try bumping up your idle a little to see if this helps with the stalling issue. I have the Cobra Fi2000 and this does help some in getting the bike to run smoothly. However, I did not get rid of all my pinging issues until I put a 1.5K ohm resistor on my air temp sensor.

seems most guys that add a fuel processor get total resolution of all querks(w/o having to resistor mod, etc). TFI solved mine.

I'm sure the FI2000 would do the job but is another solution. I am running debaffle, gutted bladder, and a K&N filter that just replaces the stock paper filter with no rubber gasket on the left dog bowl. My bike was lean especially this last summer. It had some surging issues and it would sometime just die on me when coasting to a stop. I did adjust the TPS to the max end of the allowable scale and this didn't seem to help. I ended up doing a 470 ohm resistor mod and I put the TPS back to it's original setting. The 470 was a little rich and now I'm running 220 which seem to be about right.

Thanks for the replies. I ordered an fi2000 today from Oneida Suzuki.

I have a fi2000R and works great. One warning though. If you have a standard air box its not much of an issue but if you have a Hypercharger with the vacuum activtated butterfly valves you may have to use 4 green- 2.5 yellow- 0 red setting due to overloading at stops when the butterflys are closed and you'll get a bike stall. All you are doing is leaning it out a bit. Stock settings for the 1600 are 4.5 green- 3 yellow- 0 red. I had set mine up at 4.5-2.5-0 initially but had to change it due to stalling with the hypercharger as the plugs carboned up after about 7000 miles. It did help with the stall issue and havent really noticed any loss of performance. If you do want the richer 4.5 mix a hotter plug or rig the butterfly not to fully close when at idle. Do not adjust the green any lower than 3.5 though or bad things may happen according to Cobra rep.

Before you install the modual, seek vacuum leaks with WD-40 and the red wand. Shoot a mist right into the intake (right side filter off if you have a filter there, or dog bowl off)

just a short quick blast, fast as you can in other words as little as possible. Listen

wait do it once more... Listen.... The rpm will do soming.. (probably go up)

Now you can test because you know what to listen for.

Mist on the left side at the intake ports as close as you can get. mist a split second and stop, wait and listen, hit any places there is a sealing suface. Move on to the intake port and mist each connection there, and then last the throttle plate ends.

You should attempt to hit the injectors as well. Always wait and listen between mists..

If you find a vac leak what ever happened when you misted the first 2 time will happen again .

If you have all the EPA garbage there is a vac line test it on both ends, and jit that vac pod too.

Then you can fix anything if you need to and or just install that modual. I think Cactius jack is the guy for setting it up to spec. I have the TFI.

Mine done that when it was all stock. My idle was set too low.i also started using high octane gas.
I change my pipes to V&H baggers after that also. i have no problems now. I really think my problem was the idle.

Prior to installing the Cobra FI2000 on my bike, it would "hiccup" on take off when cold. After installing the FI2000, it has not done this once. The information given to me by various tech. types and knowledgeable people with experience on this site is that the FI2000 is OK if you are not going to do heavy mods to the intake; however, if you have thoughts about doing heavy intake mods, you may want to get something more flexible. With heavy mods, the FI2000 can end up working against (fighting) other intake mods. I have no plans to make any mods to my intake, so the FI2000 works OK for me.

these bikes really do alot better at 950rpm no matter how much we want to turn them down to idel low. I have tried all rpm's and back to around 900-950.

+1 doc.....I turned mine down once for one day of riding and did not like it...so back up it went

Funny you guys mention this at this time. I have been fiddling ::)with the idle since the mods and have found I really like it at 800/850. I know I'm right on the edge, but the sound at a light is great and so far, no stalling problems or difficulty taking off. Truth is, its actually a little smoother at slower idle with the mods than it was faster without. Go figger ???
