Name that Carb ?

Recommended Posts

Picked up a 2008 DRZ 400SM. It came with an MRD Pipe, Racing Cams, and this carb.

 

Do you think this carb is off a CR ?  Tight Fit?

 

Is this in fact an FCR carb?

 

I had it off to take a look.

 

I had to drill out a hole for the bracket for the return throttle cable...I also had to bend out the gas tank lip a bit to better fit the throttle sensor.

 

Its in there but tight....

Yes it is some sort of FCR carb.  I dont have a calibrated eye to say what size the venturi is.  i'm sure someone on here has seen it before.

not the right fcrmx39 for a drz.should not have cast cable tower,idle adjuster should be on bottom not facing rear,should have removable intake bell.

It's an FCR, probably 39mm.  Looks like maybe it came off of a mid 2000's YFZ450 quad based on the TPS location and decel enrichment dealie.  TT user mx_rob's FCR39MX conversion for the DR650 uses the same carb.  When I had my DR650, that's the carb I used.  If it fits, there are no air leaks, it's jetted correctly and there are no cable issues, you should be good to go.
