    400

    yup

    the 96 came with 38's the 98 was 40's no sure about the 97 but pretty sure it was 38's,easiest way to tell is to look at the choke blade.on 38's when the choke is pulled the blade fills the complete hole of the air breather base,on 40's there is a lip of aluminum you cane see,yes the 40mm choke blade is smaller in diameter than the 38mm,noticed i said choke blade not the throttle blade

    my friends 97 sltx had 38's on it originally...now that's not to say that maybe some of the very late production ones had been switched to 40's but none that I know of.

    OK, here is what "I" have found......

    i just had a 1999 SLX 1050 here in the shop yesterday, and had the carbs off, to rebuild the accell pump, for a local customer. while the carbs were off, i looked them over, and compared them to some 1996 SL900 carbs ( listed as a 38mm)

    the SL900 carbs ( same body as the earlyier 1050 carbs, just different jetting) measure 38mm at the throttle plate.

    the 99 SLX 1050 carbs DO measure 40mm at the throttle plate, BUT "IF" you look further up into the venturi, they still measure only 38mm. ( as do the other 38mm carbs).

    so, it is "STILL" my "opinion" they are ALL 38mm carbs, just like all my parts lists, OE part numers etc show. even though the newer 1050's measure 40mm at the plate, it is still only 38mm in the venturi, thus it is a 38mm carb.

    hope this helps.

    Does that mean there is a 1 mm 'step' where the larger 40mm diameter carb base meets the 38mm intake manifold?

    NO. the intake manifold actually has a larger hole, than the carb throat. all intakes, for the 900, 1050, and even 1200 are the same. they measure 40mm.
