2006-2007 ZX14 header tuned and tested
« on: February 10, 2018, 05:16:02 pm »
In response to several people, I have developed a flash for this application.   :beerchug:

This is a great combination that needs nothing but just put on and go.   :great:

See the charts below...

1st chart is compared to a bone stock C14

2nd chart is compared to a slip-on


Thanks,


Ivan

G Pink, are yours MIA like mine are/were?

I looked for days and never found mine.  I gave up and went to ebay.  I paid 29.99, shipped for  a set of used throttle bodies...for example....

Yeah, plus I'm not really wanting to go back in. Getting lazy in my old age.

That was my one big reservation on getting the reflash was having to find them and put them back in.

I had a heck of  a time getting the screws to start.  I had three that refused to bite.  I fought it for  a while and finally realized all I had to do was grab a hand file and dress the backs of the screws. Removing the sharp edge was all it took.

Once I did that, it was a non issue and they were in within 5 minutes.   Not nearly as bad as removing them.

I know this was part of a comprehensive tune, but I found the first 20% of throttle really came to life once I put them back in.

Did you use any thread locker?

I did use a tiny amount of blue loctite.   The screws started so easily, I thought it would be a good idea.

It will be ok with no flies but there will be a very minor hesitation below 4000 if you suddenly give 100% throttle.

My recommendation would be to get a set and install them... it's a small price to pay (time and money ) to get things 100%.

Just saw this. Thanks Ivan
I {and others} have been waiting to see a ZX header plot for years.

The ZX-14 headers look like they produce better low/mid torque than the Akrapovic ZX-14R headers and slightly less peak??
    That's really good news for folks that can't buy a $1000+ header system.
{I realize the Flash helped make this plot possible}
{I assume the Akr. headers have bigger head pipes & different cylinder pairing. Which helped you reach the higher peak HP?}

Did you happen to do a plot of the C-14 w/ZX-14 header, but wo/Flash?
Explanation; Many have done a ZX-14 header install (wo/flash), but we had no plots.
                   We've been hoping to see one for years!!
                  A plot like this would show the advantages of just the ZX headers over stock,
                     and would show what is gained by adding a flash to them.

RC, you might consider removing your throttle bodies and flair the screw thread ends.
ie; Carbs/throttle body manufacturer's flair the ends, vs using thread locker {as the fuel might dissolve it and the screw could be sucked into the engine}...

Ride safe, Ted

Ted, I agree. I would have liked to flare the back of the screws.   

I could not see a really decent way of doing this.  The shaft is not very strong and it would have been impossible to go at them from the back side...well, as long as they were in place.

I do plan to check them after a few miles, but not really sure what else can be done.

Blue or red loctite is fine and should be used...

I sold hundreds of sets of smaller sub-plates for the FZ1 over an 8 year time span (which included new screws) and I am not aware of any screws that fell out.

This is not something that I would be very concerned about.
If there is a problem with the screw not tightening upon re-installation, then I would be concerned and fix it.

Thank you.  I did use my "JIS" screwdriver, as well.   Im sure you guys knwo about the JIS spec drivers. I think I learned abotu them on this forum.

 Neither Phillips or Pozidrive...its a "Japanese Industrial Standard" (looks like phillips), but the driver fits much better.

Almost mandatory for these butterfly screws. I bought this set and its turned out to be a really nice set to have.
