Can anybody identifiy this Keihin Fcr? Is it a MK1 or Mk2? It is supposed to come off a Yamaha WR 426.
Is it a good Option for a '2000 Fe600? If yes, which jetting is a good point to start? My bike has an Akrapovic Full exhaust and smets (supermoto) camshaft.
Best, Simon

MK2
The early mk1 has the pumper mechanism on the outside

Should I put my Handys on that carb or is ist better to wait for an original Husaberg 650 FCR?
 
Needle is the most important part . And jets .
Change those and should be the same .
Check the stock jetting for the husaberg fcr and go from there

Have a close look inside to make sure the rollers haven't seized up and scored and grooved the body. If that's OK, you'd likely want to fit a new vacuum release plate too.

Its probably a 39 if it was on a 426.
 
that is the best carb - the Mk2 - so get it, even if it is a 39mm.

you'll need to get rid of that air filter adapter for the Husaberg.

I do a bespoke performance jetting kit for them (100820 on the web shop)
The AFA is 100355. you might be able to make room for the blue belmouth at 100356.

According to the seller it's a FCR 41.
So I think it's a quite good catch for 150 €.

Thanks a lot for the Information. I'll wait now until it arrives, disassemble and clean it. Afterwards I'll male a list of needed parts and place an order :)
