fi2000r tuning

[metric man]

Can't call cobra today they are closed . I have a 2007 vulcan 900 classic with cobra longs and fi2000r. It ran good for the 550 miles. Then a slight pop comes out when swicthing from 1 to 2 and 2 to 3 thats it. 3 4 5 all ok no poping. I live in conn. new england US. I know i need to ajust the pods. Has anyone had the same problem?

with the FI2000r you won't be able to eliminate the popping... it's the nature of the beast. You can lessen it with proper adjustment but as far as I know any bike with a reed valve will give you popping. Is the bike Marbled?

[metric man]

No it is not marbled i thought that was only cal. bikes. If that is not the case where does the marble go and more inportant what does it do? Thankyou for getting back to me.

Marble or electrical wire nut fits in the hose on the upper right side of the 900 air breather. You can get to this hose without taking anything off the bike. Just reach in with a pair of needle nose pliers, squeeze the hose clamp and push it back on the hose, then pull the hose off. Push the marble or wire nut into the hose so that it blocks off the hose, should be a tight fit. Put the hose back on and put the clamp back on the hose. You is done. Takes longer to find the marble/nut and pliers.

During normal operation the reedvalves open and suck air into the hose and mix it with the exhaust gasses coming out of your engine. This oxygen helps burn any leftover fuel. The stock muffler pretty much hides the popping but when you go aftermarket or gutted they are out there in front of God and everybody. You eliminate the air supply the popping doesn't happen unless you have leaks around your exhaust gaskets where it will suck air in after the high preasure exhaust wave goes by.

Won't you get a fi light. The hose on the top right side of air box?

yes to the location and no to the FI light... I've had mine marbled for over a year and nothing yet.

Do you anything about ajusting the fi2000r maybe the 1 pod #4 setting is to high!

[bigdaddyeo]

most people are finding the 2-2-1 or 2-1-1 are working best for them... the
FI2000r comes preset way too high.

I have the fi2000r on my 900, as others have stated you will not eliminate the popping alltogether. Running the factory suggested setting 4 - 2 - 0 should be OK as far how your bike runs. I found this setting rich on my bike with just pipes. I have Cobra speedster longs and Thunder air kit on my bike and my fi2000r is set at 2 - 1 - 1 and the bike runs great also mileage is reasonable at 44 mpg. Remember to take all advice on here as opinions only, what works for my bike might not be right for your bike. Also go to the how to section there was an article on there about how to marble your 900.

This is from the Cobra tech support (phone) here is how to set the FI 2000 on your bike.

1.Warm up the bike.

2. A tach is very helpful here. Set the bike up so you can hold the throttle @ 2000 RPM's and adjust the pots at the same time on the Fi 2000.

3. Set the green pot. (left hand) at 0. With the bike @ 2000 RPM's slowly turn the green pot. until the RPM's start to decrease. Then back the Pot. off slightly until the RPM's are back to 2K. Your done with # 1.

4. For the yellow pot. (middle) It is a little more work.

5. Take the bike to a place where you can be rolling in 3rd or 4th and roll on the throttle hard, stop and adjust the yellow pot.

6.Start with the yellow pot. at 0. At speed in 3rd or 4th apply the throttle hard. Advance the yellow pot. in 1/2 increments until there is no hesitation at the roll on. Your done with the roll on setting. ( the yellow pot. is like a accelerator pump on a carb.)

7. Set the red pot. @ 2. You can adjust the wide open setting best on a dyno but our V twins are not too picky at wide open there is plenty of fuel ( as per Cobra). If your first two settings are spot on the #2 setting at wide open is usually perfect.

Hope this helps. It did for me.

How much of a difference will this make in power and mpg, when switching from 4-2-2 on a stock exhaust? I currently get about 40 mpg with BAK and 4-2-2

Setting your FI 2000 because "someone else did it" is IMHO silly. Cobra has a way to set the FI. If you don't believe my post (see my previous post in this thread) call cobra on Monday. Every bike is different. I have Cobra Speedster Longs and a Kuryakyn Hypercharger, I am getting 47-48 mpg every tank full and I am hard on my throttle. Cobra says you dont need the FI if you just have 1 modification. BAK & pipes should have some FI mod kit.

Well you're not going to be getting much power from having a FI2000r in the first place so by lowering the pots down all you're really doing is leaning out the mixture a little more so you're not dumping fuel out your tailpipes... at 4-2-2 you probably can smell gasoline while your bike is idling?

I have never had any problems with its current setting, no smell or leaking gas out pipes. My only concern has been that I get about 40 mpg. I used the default settings on the FI when i got it over a year ago. Other members where recommending adding the FI when you get the BAK, even if you keep the OEM pipes.

Thanks for the advice.
