I've seen a pair of hardly used Keihin FCRs for approx. 400£.
Is that a good price?
And - are this THE good flaties?
Would they match to an OVER exhaust system?
How many BHP can I expect?

(My profile is still as stock as my Trixie is, this might change)

I got a discount on mine but standard price where 1200€-ish so nice price!
Wich are the BAD flatties??
Well, over racings bike ran pretty good hey??
FCR´s+2-1-2+light porting of the head could give you 10-ish on the rubber...but WAY hard to say...to many factors involved.

Madivi,
Make sure they are Keihin FCR 41's as mentioned. New ones in UK they are about £700-£750 or so with cables, spiggots etc to fit the TRX. I've seen them sell used for £350 to £500 so yours is not a bad price.
If they are not off a TRX, Allens Performance in Nottingham have the connection spiggots for inlets and outlets plus cables etc.
My bike has FCR41's with Ramair pod-type foam air filters and a free-flowing 2 into 2 Renegade full system similar to the Over one, and has had nothing else done to the motor, and rear wheel BHP on the dyno was 90, so an increade of about 15bhp over the standard TRX's 75.
Dave.

Hi guys
Sorry for my late reaction I completely forgot about my question!
Thank you for your valuable opinions!
Seen the price I should have a go. I also have an over system at home.
Meanwhile I had decided to better save the money. Do I nedd the few extra hps?
Reading though that I could opt for additional 15 hp makes me doubtful
Try to contact the guy
