Bob,Digging up the old thread here to see what others have to say about the Newest b Cam...
I'll begin: it's Noisy! Either that our I did a poor job at setting my Clearances!? Anyone find the same?
The Torque Curve is...Interesting. I'm not sure what to make of it but it doesn't seem Linear. What I'm trying to communicate is that the power doesn't come on in a predicted manner, like starting in at 2500rmp then ramping up all the way to...whatever, say 6500. IT SEEMS TO ME that the power comes on, then dissipates, then comes on again. Sometimes if I'm in a higher gear then this seems to throw in more variables. (Still not a good explanation of what I'm feeling.) Then Sometimes it behaves just as I would think it should?? Weird. Nothing TOO Bizarre, just not the Linear response I've felt in the past. Now I'm Really Curious as to how our MAP is responding to this newest Cam. I've got a feeling that if put on a Dyno we could use the Data to work out something special! Heck, it's already Special, so, mo better!!

I was in the position to use my buddies BS3 Himalayan for a few days last week while I found the time to R&R my cylinder Head with 6mm HeliCoils. (Did a bunch of other work to it to that various 'mechanics' around here had screwed up. They even stole my Iridium Plug!) The Ride (YSS), The Power, the Over-all experience of riding my bike is SO Different, So Good now, that all of these difficult days of working out the kinks has Really paid off. I'm pretty close to calling the bike World Class! (especially taking into account it's humble origin).
BTW I replaced my Plug with a NKG CR9EIX, which is 1 or 2 points Colder than the typical 7 or 8 Series. My bike is running cooler, for sure as it's 41c now and I can for sure tell, but also I haven't change a thing and the bike is starting with just a touch of the starter, no throttle, and idles perfectly! That's a first! I'll put in a hotter plug when cooler weather comes around again...

I suspect some of the development done so far has gone out the window with the new HT-C. More duration (seems from the picture) changes engine behavior.
Interestingly enough the Kent behaves similar to HT-B a RPMs up to 5000 then it diverges. In fact the map that we have made for it is pretty similar up to that range, then it needs more fuel to compensate for better breathing and that shows off, as the bike is eager to rev up!
So, as Peter suggested, the only way to tune it properly is on a dyno with several "partialized" throttle run, say 14% / 30% / 50% and 70%, beside the normal 100% run.
This is what we've been doing, throughout several session, with Peter to come up with V6.
But even so, that map would be optimal for your bike, not necessarily for all bike using a HT-C cam, since your build is rather extreme and I don't think I could scale back the values to suit less modded bike.
It still remain to be seen.
