FCR's fitted and guess what....

Maxypriest · #1 (**permalink**) 09-05-2005, 06:38 PM

Fitted some FCR41’s from Chris K a week ago. Nice - and they fuel so well, none of the old choke shenanigans either, she just fires up on the button and idles at 1100 to 1200 with the slides rattling away. Sounds great, goes like stink and uses less fuel (55mpg). I really enjoy riding about on part throttle playing tunes with the whoosh and whistling intake soundtrack, before nailing her to the stop.

Can’t be bad.

Rather pleased. Like most 92-97 FCR owners I can highly recommend the conversion, even if Her Majesty’s Customs relived me of £113 import tax (about $200) for the pleasure...

Rock.

Congratulations on the FCR's! Probably the best upgrade you can make to the carb 2V. I think it's great that the FCR's enhance the performance so much and actually end up improving the mpg as well. Enjoy...

Regards,

Jeff

Yep- the first thing I recommend on any Duc 2 valve. And wow- $200 import tax??? Terrible....

damn, I want a set of those bad, just can't justify the cost yet as I only have less than 1yr left of riding before going over to the big sand box.

Yeah, I too would love this mod.! I am really worried or scared about the whole no choke thing. And the $$$.
I may just have to bite the bullet and do it though. My justification to my wife for things for my bike has been, "they might stop making it because my bike is ten years old now, so I better get it while I can..."

Now I can add the "well gas prices are $3.50 and this will save money in the long run..."

Okay, I am officially jacking your thread!!! I need to know two things, this is assuming that we are all using them "set up" by Chris Kelley,
1) it says that they are pre-jetted....if this is true, will my Arrow slip-ons throw the jetting off?
2) how long would it take a mechanic to install the "works"?....I already have the modded air box with K&N. Are we looking at 1 hour, 2 hours, 3 hours of labor??
Thanks guys I appreciate the help!

1) No. You may have to fiddle a bit, but I doubt it.
2) By saying "th works", are you referring to just putting on the carbs with your modded air box? If so, a mechanic ought to be able to do it in about an hour. It is really easy and straight forward, though, so you should be able to do it yourself in less than 2.

Ditto that. I'm no mechanic, and it took me less than 2 hours. Kinda fun, too! Best mod I've done so far; like night and day.

Dutch, I live in northwestern Wyoming (cold here) so I was worried about the lack of choke too, but it's really a non-issue. A couple of squirts with the throttle (accelerator pump) and she fires right up, even when the temp is in the 30s (sometimes takes a couple of tries, or you can turn the idle up to help it start). Also they do not ice; a worse problem with the stock Mikunis than no choke is with the Keihins. My mpg did go from 45 to 55 with the FCRs.

I also don't miss the choke = two twists and instant start. Even with 11:1 I get clean low idle. I didn't install them but I only get 37 mpg in hot canyon riding.

Jeff H. · #11 (**permalink**) 09-07-2005, 06:04 AM

You won't ever miss having a choke once you get the FCR's on. Like others have said, 2 twists of the throttle and some turning of the idle adjuster, depending on the temp outside and the Duc will fire right up. Installing them yourself should take between 2-4 hours, depending on what pace you go at. It was actually a fun job, just don't get the relays crossed up when you plug the electronics back in. Don't ask me how I know this...

Regards,

Jeff

I echo the replies above about losing the choke, it's no big deal, you just need a minute or so before you can take off. Sometimes it stalls out once, but never more than that. It is very important that your slow speed jets set up right to help off idle response. Mine was a bear off idle unitl I went down from the 60s I got with the FCRs to 55s. Installation is a breaze, three hours or so.

By the "works" I mean the throttle twistgrip, cable, adapter for the intake manifolds, and velocity stacks...You know the Sudco package here http://www.ca-cycleworks.com/shop/ca...cati/fuel.html

Personally, I have found that the cold starting and idle characteristic’s of the FCR’s to be superior to the old CV’s. Bonus.

Note that the kit Chris K sent over included everything I needed for the whole conversion – which was also rather fun to install.

I would recommend doing it yourself. The trickiest bit being cutting the airbox up – if you have / can borrow a Dremmel type thingy that’s even a synch.

As for $$$ it took me a year to save up for them!

Monster Man · #15 (**permalink**) 09-09-2005, 05:38 PM

mine will always start first crank when cold, but it will always die within a couple seconds, then I just restart and modulate for about 10 seconds til she's going on her own, I don't even bother with the manual idle speed anymore like I used to. Wehereas with the Mikunis I could crank for 5 seconds or so before it would fire and then the choke would speed it way up. I prefer the Keihins actually

DesmoBob · #16 (**permalink**) 09-10-2005, 12:56 AM

I agree. Used to be all finicky about spinning the idle adjuster up, 2 squirts, and fire. Now, I just walk up to the bike, turn the throttle 1/8 or so, and hit the button. Keep her running for a few moments and walk away while I put my helmet on. No problem. In colder weather, you will have to idle up a bit. You'll figure out your bike's routine...
