Gauges were $130 (got screwed on cracked cover due to lying seller) but the mileage is perfect for my bike.
I'm using a VFR sensor for the speed, I paid $20 shipped. $15 for the cover shipped, still need to get the water temp sensor.
I will also be building my own correction circuit, expect a cheap, diy alternative to the $125 speedohealer soon. I expect my price to be about $25-30 or so. Yes really.

 

Hey all. New to the site. Been rocking a ninja 500 for the past couple of years. Just picked up a 92 f2 for a steal of a deal. 30xxx on the clock. All it needed was a front fairing and gauge cluster. After looking for an f2 set for awhile (around 300-350 bucks) i stumbled on this and I must say, thanks very much for this guide. I am upgrading now to a digital dash for way less than the stock would have cost. Also, im pretty mechanically and electrically inclined so if you need any help with fabbing up the correction circuit Id be down to help plus its the only piece I am now waiting on.
Below is what I have compiled thus far searching for these parts.

Willo, care to shed any light on what VFR sensor you are using? Year make model ect.


Also where and how does the speedometer sending unit mount? The OP listed sprocket cover AND speedometer SU. None of the sprocket covers that I am finding have any speedometer su mounted.

Needed Items:
Guages F4I : $115.00

Front Sprocket Cover 95-98 900RR : $010.00

Thermostat : 37750-KV3-951 : $037.56
Same as 98-05 VTR1000F, 98-99 CBR900RR, 94 RVF750R

Speedometer SU 95-97 900RR : 37700-MAE-601 : $156.20
Speedometer Joint 95-97 900RR : 44808-MR7-013 : $007.40
Speedometer Bolt 95-97 900RR : 96001-06014-07 : $000.82

 

the sprocket cover got to be from the 95-97 900RR, the temp sensor from the 98-05 VTR1000F, 98-99 CBR900RR, 94 RVF750R will only work on the F3 apparently the F2 CDI unit does not recognize it and the display on the gauges does not show anything

 

The sprocket cover has a hole in it. It'll be visible if there's no speed sensor on it. Here's the one I'm waiting on in the mail:


Here's a 900rr speed sensor - it went for something like $50 shipped:


Now compare that to the one I bought of a VFR:


If I hold it up, the parts appear identical except that the wires are shorter on the vfr unit. I will put up the year as soon as I've actually tested the thing, but I expect it to work.

 

Thanks for the quick replies guys. Ive compared the fiche data for the vfr sensor and the cbr900 sensor. Very close model number but slightly different. I have found a VFR unit pretty cheap but I am also wondering about the CBR F3's. After checking out the fiche I come up with these part numbers for f3's. Leading me to believe that they have it on the front cover, especially since they dont have to change anything else for the mod... but when I ebay their covers, I come up empty of covers with holes in them...? Ideas?

Found one for an f3 and purchased. Looks the same as the above picture. Also purchased a vfr sensor and have confirmed that the same year conversion works on a vfr forum so it will work with a speedometer. Excited. Waiting on my gauges.

Theres a ton of conversion guides for them and they use their own sprocket cover speedo sensor with a speedhealer. Does the F3 sprocket cover swap directly to an F2 as well? That would be another option for the speed sensor part. Also, as long as were buying a custom speedohealer anyways would it really matter what model the speed sensor is since its going to be adjusted via the speedhealer? I would think that any sprocket cover with the sensor mount + any sensor from another bike also doing the conversion should work on ours if we follow the steps for their bike with the speedohealer. That would definatly open up the possibilities for this conversion dropping the price and making the parts easier to source because the 900RR stuff is scarce.


Also: Borrowed this from another forum but It should assist us with hooking up the kickstand switch to the guages.

"I just did this swap 10 mins ago and after about an hour of trying, I finally discovered how to use the 'FI' bulb as the kickstand indicator!! To add, it is also functional in that if you put the kickstand down in gear, it stalls!

I will post this on every forum in which I have researched and read about this swap! I had yet to find the answer that I was looking for and so I want to share my finding with everyone.

f3's yellow/black wire connects to f4i's white/blue wire AND NOT it's green/white wire.



I couldn't have the signal all the way to the right on because I had the left one on :P

--CBRF23: add this onto the list in the first post if you find this to be worthy !!"

 

Here's my gauge mount - I fabbed it from some 6061 aluminum flat, pop rivets and some scavenged mounting hardware.

My main goal was to build a lightweight frame out of stuff I had on hand. Anyone should be able to pull this off with some aluminum flat (or a cheap aluminum yard stick) and some rivets or bolts.


The bend at the bottom is on purpose to match the rake of the mounting hole. Once I pick up some deeper pop rivets, I'll replace the shorties. It should be fine for a week or so.

The upper mount on my gauges was broken off (seller earned some negative feedback over the damage) so I pulled the gauge apart and mounted a machine screw from the inside. It's inset to avoid shorts and actually added some angle adjust-ability in the end.

 

Looks great willow!!! Helping us save 100 bucks on the speedo healer too would be wonderful.

Just ordered all the 900rr parts. To be honest I really miss the clock on my f4i when I ride my f2. Must... have... clock.....

 

My 900rr cover came the other day and after I picked up some longer bolts, turn the edge off the spacers in the cover and bolted it up, the sensor I bought bolted right up. I ran wiring last night and did a quick center stand test of the speedo - it got the clock going - it's on the far slow side, but that's expected.

I used a 99 Honda VFR800 speed sensor. Only cost $14 on ebay. It has a shorter pigtail than the 900 sensor but it bolts right up.

Now that I have the hardware, I'll start working on the speedo correction. I'll prototype it with an arduino (ATMega368P) board then come up with the final design.

Since it will be designed for motorcycles, the final version will use all surface mount hardware for durability. As long as things go ok, I should have something going soon.

 

A couple of questions.... I don't know if anyone else noticed but there are two black/brown wires referenced in this write up. Which is the right connection for the black/brown wire from the f4i cluster? ie the f2's black/brown goes to the f4i's green/ blue for the temp. then later in the post its noted the black/brown must be connected to the black/brown. Also as relating to the speedohealer, when we are setting it up do we have the reference the factory gearing from the 900rr as the starting point and then put in our choice of gearing for our f2's to get the correct ratio?

 

I've been meaning to get on here and provide some updated notes on the wiring. For the most part, the post is accurate, but lacking in a few details.
I'll try to make some time.

Meanwhile, here's a shot of the speed sensor installed:
