Stock Settings for carbs w/ EXUP system

[Superfly]

Hi All, First post on this board. I am looking for the stock Carb settings for my 92 FZR600 W/ the full exup system.

I have noticed that when I am on the road, and as soon as I hit 7k rpm, the bike really looses all power. I am going to be looking into the EXUP system first, but I need to find the stock settings for the carbs, because I do not think the carbs are 100% right yet also because idle is a little jumpy. Any help would greatly be appreciated.

Welcome aboard finally. I gotta get out the valley and check out your FZR. Nice work. I don't recall there being any difference on the carbs between and exup and non exup models. I remember it being just the CDI, the servo and valve in the header, the "air injection" system, and the cams being different. Far as I know the carbs are the same. I haven't really dived into my carbs yet sot verify this though.

The only differences that I'm aware of is that the starter jet on the EXUP models is a #50, while non-EXUP models are a #52.5. Plus, on the EXUP models, we have the little hoses that come from the vapor canister.

I can say that 99% of your problem is with your emulsion tubes. I feel like I should be paid by Factory Pro each time I say it, but it's true.

How many miles do you have on the bike?

Sweekster, Thanks! I have had alot of fun modding the bike. Actually, this FZR came out of the salvage yard in Lancaster (on Sierra Highway by Ave I, Big Jim's old Salvage yard). I am in North Hollywood and work in Santa Monica, definately stop by, as soon as she is running right, we will have to go for a ride, SoCal has the best roads.....

RageDigital, I have been toying around with getting the new Emulsion tubes, I might just bite the bullet today and get them to eliminate that out of the equasion. The bike really is great minus this glitch. I have no clue how many miles were on the bike, I pulled it out of a junkyard and rebuilt it. http://www.fzrarchives.com/ipb/index.ph ... opic=34699 You are correct about the 50's being different, I was curious if the 107.5's I have were stock, or the PO was messing with the carbs. Could the Emulsion tubes really cause such a dramatic drop in performance at 7k rpm's?

Thanks for the replies, the help is always appreciated.

What happens is that those emulsion tubes wear out and start dumping fuel into the carbs. At 1/4 throttle or the 7k range, it stumbles due to too much fuel.

If you had or have adjustable needles, then you could simply drop them down a couple notches and lean out the circuit.

It is best to take the emulsion tubes out of the equation and just replace them.

No flippin way. Last time I was in there all they had was an Fzr tank cover and that was a year ago. Gotta go back. And I also work on the west side (Santa Monica & Sepulveda). Live in both Hollywood (got an APT by the bowl) and Lancaster (West side close to lake Elizabeth). Small frickin world.
