This is what I want, given that I have F4i brakes and SS lines ready to go, yes or no?

Definitely not! You need a F4i MC to be properly matched! Besides.....I am bidding on that one and I am determined!

The stock M/C is working out great for my F4i calipers (IMO).

No worries, if you're already bidding, I'm not that concerned about obtaining it

I was leaning in that direction myself, actually.

It'll work, but the piston is larger than the VTR or F4i mc, so it will give a firmer lever but less pressure on the caliper pistons for a given amount of effort at the lever. The F4i mc and calipers work very well together. The stock mc should work well, too.

I am not bidding yet, and I may find that my RC51 mc is fine, so don't worry about me.

True, but it'll be less spongy, and that's what I think is least liked about the stock brakes.

Agreed. When I still had the stock front end I tried a 929 mc and couldn't get the power I wanted although the lever was very firm. I think that's highly dependent on brake pads, too.
Before I swapped forks I had the complete F4i system and it was just right--powerful and firm.
Right now I have the 600RR system with the 954 forks and it's a tossup between that and the F4i system, which I still have. With the stiffer forks and larger rotors, braking is no longer an issue.

No sponginess here... although I am running Galfer lines.

When you talk about the brakes feeling 'spongy', is that just in reference to the amount of play in the brake lever?

Yes, partly. I particularly didn't like the amount of travel it took just to get the initial bite. Then, once bitten it would take much more to get real braking power from them. The 929 m/c helps but then you're left with a "wooden" feel. I fixed that with EBC HH pads which have great initial bite and relatively good braking performance. I later tried Galfer wave rotors but didn't feel significant performance increase for the money I spent on them. Still, it was nothing compared to the 1000RR setup that's on there now. Woohoo!

I have an F4 MC, no lever or clamp (use your stock ones, they will fit) but in good working condition. $25 shipped.
