But I guess I screwed it up and started a new thread...anyway...
I put 39mm Keihin flatslide FCRs on my 850, and I love them. I had put a pair on my Ducati 900SS and they positively transformed that bike, so I was predisposed to them. My 850 ran for about a minute with the Amals when I first got it, then wouldn't start again, so I don't have a great basis for comparison, but still I think the Keihins were a big step in the right direction based on what I hear about other alternatives.
Only downsides, beyond "non-stock" complaints, are cost - four figure$$ from CNW, perhaps a bit less from other sources, but I wanted to be able to call Matt Rambow if any problems (there weren't), and a HELL OF A TIGHT FIT. I didn't think they were gonna fit - no way. But I shoehorned them on. Have to hold left sidecover on with a cable tie (no room for dzus fastener anymore), and they do contact my right side petcock somewhat. Also, the air filter box, with attached ignition switch bracket has to go (substitute available from Norvil, as I understand it).
Now that I think of it, I've also had to rejigger my battery holddown arrangements, but I think that's because I put a huge electric-start-capable battery in there (which the bike sure doesn't need - this mod I regret and will probably reverse at some point) - not remembering which particular mod led to that issue. Readily resolvable, in any event (bungee cord!)
