Fuel Injection kits for the FZR400, FZR600, YZF600

[feef]

nice one. Keep us posted on progress.

I've just started renting a small unit in a local industrial estate for my partner's business. Having spoken to the chap next door a couple of times about bikes and cars, it seems my new neighbour is a friendly CNC and machine shop. So if you need anything made up, maybe I can help out.

i understand the want for rebuilding or building all together i am a mechanic by trade and love to do that sort of things. i just think if it was more affordable to do on a middle class income and supporting a wife, i would be more interested in it. but trust me i am very interested in it but it was hard enough to convince her that i needed to spend 2000 to get a bike in the first place.... but if i could find a kit like that for maybe 1000 i woudl do what i could to be able to get it because so far that is the only draw back i am seeing from having my bike for abut a month is that it has carbs and is cold natured as crap, and a lot harder to get adjusted right.

CB,
if you did not like a challenge, you would not have:--
a}Got Married
b} bought a FZR
c} gone the whole 9 yards and bought an FZR when Married

That is all true. Its not the challenge. I love a challenge its the money thats the issue.

Fuel injected FZR400/683??????????????

oh yes I did it.

[feef]

Whoo!

Nice one

friggin awesome! Can you take any closeup pics and video that's not sideways

super awesome, probably a first for the community!

[Kurlon]

I wonder if you can epoxy the slides in the fully raised position so the butterflies are the only throttle like newer EFI setups? Otherwise, Nicely done!

[Freestyle72]

Ya that could be done, however as I understand it those slides are suppsoed to help smooth the throttle responsose out some. Somebody correcty me if I am wrong. On newer bikes they usually have a secondary butterfly to help do something similar.

[DonTZ125]

There is apparently improved large-movement response by holding the slides open; Graves makes a set of hold'er-openers for people who want response NOW. As Freestyle said, small-movement response at low throttle opening is smoothed by the slides.

[Kurlon]

I tried diving through your project thread to see how much work was involved in re-spacing the throttle bodies, with the pics missing it made for an interesting read... Knowing it can be done though you've inspired me to try this on my 400 race project. I'm going to try and reuse the R6 ECU and harness though, plus a piggybacked PowerCommander to simplify trackside tuning. So far it looks like the biggest challenge will be the cam position sensor. Doing some digging it's a regular TTL / 5v output, I think there is room to modify the valve cover to have it trigger off a cam lobe directly instead of the trigger wheel on the R6 exhaust cam. It just needs to fire between the right set of flywheel triggers, so I've got 90 degrees of crank rotation 'slop' to work with. I'll need to invert the output which isn't a big deal. The flywheel trigger is just a modification of a race rotor, cutting down the long tab so it's 4 matching teeth. The fuel pump problem will be another excuse to get an aluminum tank made, I'll just have it setup to take the R6 pump assembly directly.

[DonTZ125]

Be careful how you trim it - I believe the '03-05 R6 timing rotor is a 4-tooth, but with one tooth slightly offset for indexing. The '06+ uses (I think) a 22-tooth with a 3-tooth wide bank filled in.

[Kurlon]

Good to know, I'm going to try and get an R6 donor to gather timing info off of before I dive in too far as a baseline to work from.

Nice attempt, gota love the video nice wiring. One question

Why did you not blip the throttle?

[Freestyle72]

Throttle cable wasn't hooked up.

However I finally got my tig welder running properly today so I can finish welding up some of the brackets I have been waiting to do (ie throttle cable bracket). So when I get some time I will try to get after it.
