I've been fighting a strange issue with an FCR39 that I've been attempting to fit to my '03 FE400. Well, after several attempts I'd all but given up for a while. The only thing I hadn't given a go was putting in an OEM fuel screw. Well, I had an OEM fuel screw in my container of jets-n-stuff. I installed it and all is well. So I had a look under a magnifier at the metering portion of each and the after market appears to be a bit thicker, so much so that some of the aluminum was scuffed from the FS orifice up near the pilot passage. :?

Here is a photo of the taper of the after market. Notice the anodizing is scraped away and some of the material has collected at the base of the metering needle. I don't think it's a function of over tightening as the material begins to be affected mid way down the metering needle.

Here is a photo of the after market and OEM side by side. Notice the taper of the two is different and the diameter of the OEM is smaller than the after market.

On the flip side, I'm VERY happy with things as they stand. I just went for a 30 minute ride (45 degrees F in May, you gotta love Michigan) and the bike ran very well.
Thanks,

M.S.R. = Malcom Smith Racing Tha'ts the brand anyway, just bought it from the locale bike place.
I'm sure that most manufacturers get them from the same place. When I get a minute I'll get some measurements off of the red one. The OEM is in the bike and I'll not have time to pull it and mess with it for a while.
The other thing is, the literature states it's for an FCR carby. Does not specify FCR, or FCR-MX.

i looked up the difference in the two that zipty offers and according to the info, i should have one type for my mk1 carb (fms2) and the other for the mk2 (fms1). i have the fms1 in both of them (had to modify it for the mk1 carb) and the tips are identical. the difference is the length of the body where it comes out of the bowl. i think you got a lemon :cursin:
if you look closely at yours, it looks like they never machined the tip, just skipped that step and went straight to the anodizing.

Me thinks me got a lemon too. Yeah, I just checked the MSR website and they list one for the "FCR"... The part number denotes the color of the unit. A missing $7.00 piece of brass (CDI Jet) drove me batty with the Dellorto, and a $24.00 poorly manufactured piece of aluminum drove be batty with the Keihin. 8O
