fcr41

I recently posted this '99 FE501 with a FCR41 for sale, and I thought some people would like to see a current Dyno/AFR chart for this bike. I am a tuner with my own Dyno for my Land Speed race team. I know the FCR's very well, and I spent an afternoon dialing this bike in. It has a "Big Gun"...

Don't really know if this is correct forum.. My -99 501 ran fine. Finally got around swapping Dellorto for Keihin FCR 41. Bike now won't start. Keeps fludding the plug. Spark seems good. I tested SEM and got 2.90 Red/Black 16 Green/Black Checked valve clearances 3 times. All good...

I recently purchased a 2003 FE650 for a great deal. Didnt want to start when i bought it. Adjusted the valves, changed the oil and coolant. new iridium spark plug and cleaned the dellorto carb. Fired right up, took it for a test ride, great. Deceleration pop noticed. Threw an fcr41 carb on...

While I am waiting to receive my parts for a head overhaul I was looking through the boxes and boxes of spare parts I had on this husa and found a fcr41. The carb seems to fit perfectly in the boot on the head, but it does not fit in the frame boot. The FCR is about 97mm with a 62mm inlet...

Hi, I just acquired an FCR41 MK1 carb for my 2002 FC550. I tried to order some of the Sudco parts from my regular dealer, but apparently they are very slow to fill orders lately and he recommended it only as a last resort. Does anyone know where I can get my hands on the typical parts as...

happened a few months ago now,but could have been sooo much worse. the old faithful started backfiring for no apparent reason & this be the cause. be weary this will start to happen to every old berg its just a matter of time, or any brand that has an keihin fcr41 carb on(which is most). ..weed..

Hi all, Think about borrowing the FCR41 (MK1) off my currently broken 650 to install on my 02 FE501.... Anyone got some jetting specs to get me in the ballpark?? I dont expect spot on jetting, just something to start tuning from. I have 2 needles to initially consider- an OBDVR, and an...

One of these is on UK ebay for £190. 2 more days of bidding to go so could rise even more. Is it worth the price?

I was wondering if an fcr41 would fit and work on my 02 fe501. The carb is off of an 05 Yamaha yfz450 atv. I am not sure if this would make a difference. The idle adjustment looks to be in a different location. Is the tps required to be hooked up? I am not sure if my Dellorto has a tps. I will...

Bit of bike history first, it’s a 03 Fs650e with an FP Ti pipe and a FCR41 carb with a 175 main jet, Iv had it about a year now and its ran fine, until about a month ago at a track day at Lydd. I noticed that on hard exhilaration out of the hairpins it would stutter slightly then be ok...
