Fzr 1000

Woot looks like it may be dyno time tomorrow afternoon. Local shop Cafe Racer in downtown Kansas City, may be able to squeeze me in.

Hopefully I can get some pics/video.

I was told by a member of the FZR archives forum that since I don't have the exup valve that I would never fully eliminate the stumble at 3k.

There are lots of guys who put full SS pipes on their fzrs and I find it hard to believe that you cant tune the bike properly without the exup
...Guess I'm out to prove him wrong

A friend of mine has swapped to SS pipes with no exup valve and his bike doesn't stumble. At least not when I rode it. Of course most of the time I was riding it well above 3k

I can ask him how he set it up if you like.

That would be great. I'm betting that once I lower he float level the bottom end will clean up.

I've sent him an email about it. I'll let you know his answer tomorrow. I don't recall exactly how he did it, but I know he had an issue with that exup valve before.

Heard back from my friend with the FZR and it looks like I was mistaken as he says his bike still stumbles at 3k without the EXUP... This is what he said.

"I had three sets of carbs,jet kits,lots of stuff but as good as I got it it will not be perfect from 3 to 3.5 thou without the exup.
The EXUP costs power at full RPM but throttles better at 3 to 3.5.
I ultimatly got it as good as I could and learned to ride around the stumble area. One guy at trackday with an FZR told me they all did this once you pulled the EXUP valve????

NEVER DISCONNECT THE SERVO MOTOR TO THE EXUP,it will not rev above 4000 if you unplug it,FOUND THAT OUT THE HARD WAY.

TIP TWO,,,,,,,,,,,dont modify the airbox in any way,same reason as above,STOCK IS BEST!!"

I hope this is somewhat helpful, at least know that someone else was able to set the bike up to be ride able. I've ridden it and I didn't notice a thing. The engine makes so little power at that low of an RPM that you don't spend a whole lot of time there. The higher you take the tach the happier the engine.

Well dropping the float level down to 15mm did the trick. Zero stumble roll on from idle past 5k.

If I snap the trottle wide open at 2-3k it will bog a bit. But the engine really likes the higher rps and doesn't have the bottom end grunt like my gs1100es.

I have a suspicion that the main is a bit too large. Wasn't able to get on the dyno today but hopefully later this week or early next so I can confirm.

It's not easy or very safe trying to do WoT runs to redline around where I live

With the plug in the main air jet from the kit, the bike runs rich, so I am thinking the 124 will work better than the 128 and the needle will then be raised a notch or 2.

As it sits right now with the fairings off still.



My fathers Packard in the background. Had to fix a headlight for him.


Picked up a 94-95 1000 fairing. Has the cat's eye dual headlights. Really dig the look over the single light.



This is the European color scheme. If I decide to use it I'll be repainting it to the red/white/blue color scheme of the 93. Need to find the inner panel covers that go over the ram air tubes. They have a slightly different shape than the ones from the 93. Have all the other components for the fairing though including the mounts/brackets.

It is in better condition than my current fairing. A few cracks around a couple mounting holes but at least no large missing pieces like my other fairing.

the 93 Fairing for comparison:

with most of the tuning finished, I decided to get the ol girl all dressed up.

I put the original fairing on for now. It hasn't been finished yet, but I wanted to ride it!



Still need to clean up the rims. A light polish would make them look really good, or maybe white paint.
