Hey guys,

I've read many articles with specs. on FZR 600's. Some show the 1994 FZR 600 as an FZR600R with about 100hp and say it's a YZF. I have also read about an "Exup" model with an extra valve. I have a 1994 FZR600 and I think it's Originally from California.

My questions are, Is mine an Exup model? Is an Exup model slower at take off to reduce emissions? What's the stock horsepower on my bike?

Thanks in Advance.

Please spend a day or so looking around the site. The info you're looking for is pretty basic FZR stuff. The short of it is that the EXUP system is an exhaust valve system that is indeed for emissions. However, a nice little side effect, is that the EXUP models had great mid-range performance due to the system. And yes, if your bike was originally sold in CA it IS an EXUP model. For the 600s, only CA was alotted EXUP. All other 49-states were alotted, well, 49-state models (or non-EXUP).

Fo starters, read this:

BTW, the quick way to see if yours is an EXUP is to look at the exhaust between the bottom of the lower fairings.

That number rings a bell to me too. But at the rear wheel, I think RacerD's numbers are on the money.

when i dyno'd my stockish setup i think it had 74 at the rear wheels with 24k miles and a slipon and a k&n filter and 17 negative horsepower to spin the drive train so thats roughly 91 at the crank so 100 at the crank on a fresh fzr seems possible cus i know with the tinkering i did its capable of over 100hp at the wheels

The FZR600 is rated at 90 crank HP and the YZF600 is rated at 100 crank HP. My FZR Dyno'ed at 79.8 wheel HP with stock jets, K&N drop in and full Yoshi exhaust. The EXUP does not improve HP. All it does is help to create more back pressure in the lower RPM range which helps generate power earlier (at that RPM range). The "extra" valve was in the 750 and 1000 valve head which is called the "Genesis" engine. It has 3 intake valves and 2 exhaust valves for a total of 5 per cylinder.

That makes sense. I've seen a some websites say around 100hp and others 75. Maybe some are stating the crank HP and others Wheel HP.

According to the pictures, mine is an Exup Model. Thanks for the links FZRBrandon.

Thanks guys.

Sorry to get off topic a little but i'm confused about the "Genesis" motor. I thought they were all badged as "Genesis". Ive got a 600 with "Genesis" stickers. Again i thought that was what they called all those engines.

It's all marketing. Yamaha started putting "Genesis" on a lot of things. The true "Genesis" engine is the 5 valve head. Yamaha was the only one to use it (on the FZR750, FZR1000, YZF750, YZF1000, and YZF-R1) and finally stopped with the 2007 R1. EXUP is the exhaust valve, which I'm sure Yamaha was not the first to do but was the first to use it on most sport bikes in it's model range and market it. And Deltabox mostly refers to the chassis not the swingarm.

Don't forget THE first Genesis motor the FZ750. Also part of the genesis equation was the forward inclined block and downdraft carbs, so they called the 600 a genesis even though it had only 4 valves. I think Yamaha was the first to use the EXUP type system and they were also the first to use the YPVS system in the 2 strokes which does the same thing - tunes the exhaust system for low mid range power and also top end power. Usually an exhaust system does one or the other.
