Keihin FCR FZR600/400 Gurus Needed

Beeb,

Selling off some old parts. I found a set of 33mm Keihin FCR's in storage that I bought over a decade ago that look to be brand new. They have no spigots or bell mouths but everything els is there. Anyone have any spares laying around to complete these carbs? Will the 33mm's work on both the 400 & 600?

Cheers,

Jason B.

 

FYI, I used 33s on my FZR400 with ported head and big cams. Assume, but don't know, they'd work on an FZR600 as well.

 

Interested in selling a set?

 

Talk to Steve at speedwerks. I recall those being to much for a stock 400 unless it's a substantial motor build. They will work but you may actually make less than stock carbs. I would think they would be ideal on a 600. I have them on a 565/489 motor. You should still be able to order the parts you need for them

What size would be for a near stock 400?

 

Stock carbs

 

Boring

 

We ran 32's on mild engines. Only a well built superbike engine could handle 33's.

 

Agree with that

 

Some pics of the carbs, saw the link above for velocity stacks, should just need a set of manifold spigots and they are good to go.

If anyone is interested in them let me know, I have no use for them.

 

Pm sent

 

How much?

 

Carbs are Sold!!

 

Thank again!

 

Anyone know the part # of the correct Spigots?

 

I just used the stock ones. opened up to fit bore of carbs.

 

You mean the rubber intake boots? Heat them up at all? The spigots seem a bit bigger.

 

Yes, the rubber intake boots. Didn't heat them up. Just used a die grinder and assorted cartridge rolls; was porting the head anyways.

 

Cool. That cant be right tho . I do see Sudco sells "carb hold downs" that are new intake boots. Also wonder if the yzf600 boots work
