Hello boys. Is the Keihin FCR 41 MX to big for my 501 -99? It comes from a Suzuki RMZ 450. And is the change to the Keihin worth it, my Dellorto works fine and allways start easy cold as warm. Have smooth delivery of power in the lower rpm`s and the bike almost never stalls if i don`t fu**...

Took apart my FCR carb and came across a couple of strange things. First off all, the pilot fuel screw on the parst diagram it shows that on the pilot fuel screw there is a spring, a small washer and a small O ring. On mine the O ring was missing does anyone know wich size this o ring is? The...

Hi all Bergers, I have decided to upgrade to FCR Carb. Just bought one off Ebay from USA. I have no knowlege about em' so if somone in here can tell me from looking at the pictures if this one will fit and what problems lies ahead I will be greatfull. And what kind of FCR this actually is...

Phew! Only had my Berg 4 weeks and I don't seem to be out of the garage fiddling with it it! If it wasn't for this site i'd be tearing my hair out! I had some problems with the bike holding an intermittent high idle when warm so I thought i'd start from the beginning and make sure everything...

H iguys got a MK1 FCR with no choke circuit, the bike starts and runs well hot or cold apart from being a bit lumpy with a tiny amount of throttle on...... the jet sizes are as follows; Main 152 Pilot 62......... seems enormous compared to what i've seen in the docs. Main air jet 200...

the mk 1 FCR 39mm that I have doesn't have any choke fitted. Has anyone come across this before and does anyone have any suggestion how I can start the bike more easliy. Currently I have to give it a few squirts from the AP and then catch it on the trottle and keep it reving for a few minutes...

A topic I've been interested to get feed back on is the FCR 41 vs. the 39 for post 04 450's. The FC when made was equiped with the 41mm and all japanese MX 450's are as well. Sredrum off of TFZtech will taper bore the 39mm to 41mm for $125 including shipping back to you. Cheap mod if its worth...

Sorry for posting here but my buddies computer is down and I am just trying to help a friend. My buddy has an 07 EXC 450, Street legal model. Rarely ridden. Lansing Cycle told him to richen the jets since it is set up lean for emissions. The problem is when he put it back together it ran fine...

Just bought an FCR off ebay, apparently from a 550 but has no choke, hot start or breathers fitted??? The jetting seems spot on and the bike has been transformed from the old Dellorto. Has anyone else come across an FCR with no choke or is this common on older versions? Not even any obvious...

Hi All, This is an interesting one, if you check your float height on a FCR by the down load official manual it says the float must be parallel to the carb body, if you go to the Keihin carb site the float height is set at 9mm, they are not the same. If you go by the manual when the float...

Destined for the hall of shame or good tuning aid? http://www.performance-design.net/flo_commander_2000.htm

http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... NA:GB:1123 at last, some sensible prices for an FCR. this one comes with the right throttle cables, belmouth and all the jetting right yet still didn't make big money. 7 years ago they were £300 and then you had to spend another £80 getting...

Hi all as you may or may not know i have bored out my 41mm fcr to a 43 mm and the problem I'm having is that at a constant throttle opening i am experiencing a slight miss siting at 3800-4000rpm at about 1/8-1/4 throttle and the miss seems to happen every 10 seconds or so any idea ? . to...

Has anyone tried this carb on a FE450E? Will it work? Does it give the bike a noticeable hp increase? Thanks for your input. Guten Tag, Geronimo

Current mision is to get my 400 fitted with a 39mm fcr mk1 I know the info I need is in here somewhere but for the life of me I cant quite figure it out so I'm hoping someone can steer me right. #1 I've read that Yamaha WR cables fit but all the ones that I've seen are a two cable setup...

I have finally got around to installing a FCR MX carby off a 02 WRF250 onto my 03 FE400 and I will not look back, it is just so much more responsive, smoother and more predictable and along with the rekluse clutch just fitted man I am excited. If you have been putting this off as I did then...

Hi all I am considering boring out my 41 out to 43.8 and have been told it is quit possible however I'm not sure where to bore it straight through or. offset to the top if any one can alp please feel free Cheers Matt :?:

While in the process of jetting the FCR carb on my '08 KTM 250 XCF-W, I noticed that the AP squirt is decidedly off center, i.e. squirts noticeably to the right. I would guess that the squirt would hit the right side of the intake port within inches of entrance. Can the AP squirt direction be...
