FCR's

[Yilt]

Hi folks,

I've been contemplating FCR's for the Rex. I'm currently running Remus full system with K & N filter. Not sure if the Carbs have been jetted by previous owner, but i'd presume they have been. If I get a flatslide carb, would I have to junk the air box and place pods on to replace the K & N. And would there be anything else to do to it ? I remember putting a Mikuni FCR on my ex Harley Davidson Sportster and the performance diff' was incredible. Would I see a vast improvement on the TRX ? They're expensive, so it would have to be worthwhile. Hope you can assist, many thanks.

Search is your friend

You'll find dyno comparsions and all manner of information

But yes, pound for pound, FCR41s are the best performance mod you can make

No , air box adapters are available for the flatslides.

Likely the carbs were not rejetted the TRX runs a tad rich up top anyway so there`s no problems normally,some folk fit dynojet kits though..
To give you an idea of power gains you can expect at least 10 bhp,I saw more than that once I fitted my FCR`s and I`ve not done the TPS(throttle position sensor)mod either,some say that`s worth another 2>3 bhp too.It basically sets the ignition at full advance.
As Phuk says,it`s all on the forum just use the search facility and you`ll find the threads.

Yep. I've got a pair fitted to my bike using the airbox and they're brilliant Definitely worth it, if only for the noise, but they do give a good power increase even with the airbox fitted. I removed the trumpet from the top of the airbox and raised the front of the tank a little using a spacer under the front mount.

Thanks for the replies folks, it's much appreciated. I don't post much on this site but visit regularly. I'm a bit afraid of making a prat of myself, but hey if you don't ask, you don't get. I'll have to start saving for the FCR's, can't wait. I've had the bike for a few months now and don't think any bike that I've ever owned puts a smile on my face like this one. Never ever going to get rid of it, it's part of the family now. Take care everyone and thanks again. Yilt

I had restrictions with the top end power range with the air box fitted and once I ditched that I found in top gear it pulls past 9,000rpm now and I just ran the blue bellmouths supplied with the FCR's with a filtersock.

Not sure where you are Yilt but you could always try locating a second hand set on Ebay,that`s where I found mine at £250!
Had to get some inlet stub blanks and cables from Allens(UK)and some sock filters from Ramair but quite a cheap conversion all up.
Alternatively visit the States and `smuggle` back some in the suitcase,check out this price for a new set :

That`s equivalent to £540!

Anyone else had any luck or responce e mail wise from the link mincehead put up there from the US motorcyclecarbs.com.. Been waiting just over a week for a reply with no answer,and I sent two emals ,from seperate adresses just to make sure..

You could try an international call Cobba,obviously check out the differences in time zones first.
You could keep it quite brief,ie:

"ANSWER MY FOOKIN EMAIL"!

please.

By the way,I`ve not contacted them,nor know if they`re still in business.I note they`re in Roswell,maybe the aliens have intercepted your email Cobba?
Mind you`re not visited in the night and anally probed!

(I know it`s Roswell Georgia,just having a bit of a laugh)

[cobbadiggabuddyblooo]

Well I'll stratigicly draw a picture of Kevin Rudd on my arse then With the amount of Shit that he speaks and he alway was Dickhead in my eyes(especially being my local federal member) The aliens might think there at kioto and want to take a carbon footprint reading with their probe ..See how much CO2 gas he gives off..

KRUDD is a tosser alright,like Tony Blair Australian cloned.

[cobbadiggabuddyblooo]

Yer he hasn't got a sense of humour either Like I said being my local member when he got caught out in the strip clubs a few yrs ago I mounted a pole on a piece of ply board and walked into his electrol office and presented him with it for his wife to practice on a bit of pole dancing for terese to get her back in shape OOOOOHHHH BABY
