And since I haven't replied to my own thread enought already, factory pro makes a big deal out of the 95-97 carbs...
"STD drop-in carb recal kit
NOT possible...no way, no how. If anyone tries to sell you something that "drops-in" - forget it. Call Muzzy, call us. It's just not acceptable.
And if you do find a "dropin" kit, the only way that you'd think that it works is if you test it on a dj dyno - :-)"
Slightly complex to install. Use with stock or aftermarket exhaust, makes best power, overall. Period. Used by nearly every Pro AMA roadracer in 95.5 to 97 and absolutely the best performing kit for on and off track use. When properly tuned, this kit produces the best low-end and midrange possible - and adds 2-3hp to the top-end power. This is the ONLY kit to use.
Sure - it's a bit more expensive - but there's more parts in it. But - if it takes more parts to make the bike it's best - that's what we will do.
This kit was the first of Factory Pro's "1.7 RaceKits" and the development of this kit was only possible with the 4 Gas Factory Pro EC997 dynamometer system. Other companies, using dj dynos, were incapable of refining the 6r's odd, stock carburetion configuration into a setup that produced more power, not only on a dyno - but on the track or street, too.
Base settings for stock and aftermarket exhaust systems and slip-ons included along with the famous "Pink Sheet" - Factory Pro's CV Tuning Guidelines for getting the tuning perfectly adjusted for the smoothest, most powerful machine possible."
Is it really that hard to tune these carbs? I was reading somewhere on factory pro's web site that it took them something like 6 weeks to really get this kit to work correctly. That just seems excessive.
