Mine works well. It has good throttle response and whatnot. It came with the bike when I bought it so I don't know how much difference it made over the stock CV carb. If it had the stock carb it would have been the first thing to go in the trash. I have managed to rid my whole fleet of CV carbs and that pleases me.

I remember you telling me that . It seams expensive to pay $500 for a carb , thats why I want to get an idea of the performance potential .

Stan, you're welcome to take mine for a ride and see if you can feel a difference. It's stock, other than the FCR and HotCams. FWIW, I rode Matt's DRZ with a big bore kit and stock carb and I'm pretty sure mine would stomp his .

I'm going to give this a shot but I've had a full day if ya know what I mean

Without other mods such as cam and pipe.Which increase CFM of the system You might enjoy some throttle response and a few HP.

If the current carb is moving the max CFM's that the valves and pipe can push out there will be little gain.

NOW if you buy a full pipe,cam and carb I can make that bike rip ass.

FCR is a dream to work on. I love those carbs! When done right, Gus is right, the f'in rip.

now your talking the stock carb maybe limiting CFM.

If you have the other parts the carb will be everything they need.

Keep in mind it may never be as friendly as it is with the stock carb.

velocity is what the fcr offers not so much size but CFM is cubic feet of air and gas.per minute.

big difference in throttle response and off throttle power. probably not much of a difference on top, although the FCR kit is 3mm bigger than the stock CV 36mm.

worth $500? well, it'll make more of an improvement than a full exhaust, so how much did you pay for that?

if you don't want to pay 500 for the TT kit, find a used stocker off a kickstart or E model. I can't imagine that a KLR uses a pumper carb does it?

KLR uses a larger version of what I have .

no no no no!!! no st leagal bike has a carb worth having, the fcr has an accelerator pump and direct slide, the mikuni's diaphragm carb is what you are trying to get away from, it dont matter how big it is when you dont control the slide

constant velocity diaphram carbs suck for performance.

I'll sell you a 41mm FCR w/ removable intake bell for $250. it's a little much for a DRZ though unless you are planning on doing a lot of engine work (big bore, stroker crank, porting, hotcams, etc)

My FCR up date :

Now I understand why the FCR is really the first mod that should be made . The bike pulls harder and faster to the rev limiter than ever before . It idles good and responds well to throttle input.The main thing is the difference in power , it screams. With my weight and height , I cant loft the front wheel with street gearing with ease . I am sure this will be more fun with offroad gearing when the time comes . The bike hads other mods as well , but this is definitely the first one to do .

In retrospect , I suggest to buy a new carb that is ready to go out of the box . Plus , you dont have to worry if its worn out or not . I got lucky with mine.
