So who has an FCR carb?
 
Ive been thinking about getting one because it seems like everyone says it will make more power, but all the bikes ive ridden that have them, like the KTMs and Hondas, just dont seem like they have the response that my berg does. Maybe its the bike and not the carb?

And which to get? I remember a DR-Brad posting something about being able to get them in the archives, but have not seen him on here lately???

Also, for the bigger bergs the CRF carb may work, but which year is the best to get?

Either way I think the price is $400+ for the conversion.

Sudco has them now.

I fitted a FCR39 off a WR400. Pics and jetting specs here:

Worth the effort, more mid range torque, more responsive and hangs on better - easier and therefore quicker to ride. Do it. Incidentally, I spent a fair bit of time playing with the Dellorto, as a result, top end isn't much, if any different, nor is starting. 1-2, occasionally 3 kicks when hot. I'm still working on cold starts.

It indeed makes bikes start better and not choke so to speak, however like results can be achieved with a properly tuned dellorto and it is tons cheaper Ask lineaweaver!


The honda like characteristics are simply refered to reguarding starting ease, The power delivery and throttle response will only get better.

the dell orto makes the bike vibrate like hell compared to the keihin. i did over 30 mods to my dell orto carb and even first time out the keihin was better. i've got the jetting dialed right in on the keihin now.

so much so that the factory settings are the same as mine bar the MJ/MAJ on mine. i am trying a very large choke jet soon in order to clear up the starting issues i hope-for good.

one thing to remember is that although you might get a used WR carb etc you will need the following which all add to the price;

yamaha fuel pipe (and clips ) i don't use clips at all.
a 2 into 1 union on the carb (i have a spare one for sale)
another inlet rubber so that you're happy to cut it up/about
KTM 400/450 throttle cables
KTM 400/450 throttle housing
fresh grips
many new jets and needles through both keihin dealer (sudco/allins) or through yamaha
block off the TPS
new belmouth spigot to suit the larger inlet 'sock' of the husey than the yam

all this adds up.

worth it? for a better bike but probably financially-no.

the MK 1 carb will need 'de-octopussing' and the 'Taff Mod' and the MK2 needs the 'BK mod'.

Power,
 
The best thing about fitting a FCR39 is the instant throttle response.
You CAN get out of it cheap if you use some nouse?
I got my FCR39 MK1 from E/bay in the US for $180 Aust delivered, not bad ahh? You will need the throttle assy and cables from the KTM 450, cant remember how much they were. I used normal fuel line, and a stainless steel T'peice I was given and they connect on the exhaust side no problem. I also made my own flanges from nylon on fuel and air side of the FCR. etc etc.
Just keep your eye on Ebay and see how much you can save? I have also just bought a starter motor(mine has shit itself) from a CBR600 (same spline) for $50 Aust?? and I will modify it to suit my Berg.

My advice

Talk to Mr. Lineweaver he did mine and it made one heck of a difference did not break the account either fairly cheap and well worth it.

Taffy April 28th, 2004 09:56 AM

what's fairly cheap?
