He'd better not. That is the "safety valve" - tire breaks lose before the belt does!

Did I ever say there was anything "different"? You implication is quite suspect.
If you were asking if I build motors for a living, the answer is NO. My "real job" is in IT. I build motors for fun and because I can.
I'm just sharing info. If ya don't like it, GFO of the thread.
I DID say "numbers don't mean DICK to me". That is TRUE. I posted the "numbers" because a LOT of folks ask. I did NOT build a dyno queen - "number chaser". I built a motor that I can ride across the US whenever I feel like it (I actually DO ride), and not have to worry about some radical *** cam beating the roller bearings out of a lifter - which happens more often than you might imagine.
Did you read my previous post ~ the one where I said it has a comparatively small cam for a 124? If I were chasing numbers, I would have used a much more aggressive cam like the one from the (uncorrected, un-smoothed, unsolicited) sheet you polluted the thread with.
I'm not real sure what your motive here is, but I hope you get more courtesy & respect from others "if" you choose to post info about your "117 in progress".
Best'a luck to ya, PAL.

If you look at Phil's chart, the area "under the curve is most impressive, the torque starts early and the line stays flat through the rpm range. The chart the "other guy" posted is not what you look for in a street build, very peaky and the engine would feel that it had gone flat past the peak.
And as Phil said, he does ride, I have been on a trip with him and there is no doubt about getting out and rolling long distances.

That's FUNNY!!!!!
Ok... I got the heavy diaphram spring installed in my Rivera Pro-Clutch, & now it holds.
I was able to go by Ed's last night and let him finish up my initial tune. The results were: 139/151. It rides and runs VERY nice. Ed did a fine job on the tune, as usual.
The "current config" is using a Boarzilla headpipe and a universal (Race Car) SuperTrapp muffler can with 13 disks and the open "RACE" end cap. I forgot to bring my disks, as I rode to work and went straight to Ed's. We did try running it w/o any end cap at the end, but it threw the tune way off & I didn't have time to hang around for a retune (even though he was willing).
Before anyone asks... "Yes", I am running a smaller cam than one might typically run in a 124. I already had the 590, and I frequently ride this bike on trips. For both of those reasons (not to mention that "dyno numbers" don;t mean dick to me) I stayed with the smaller 590, as compared to something like the TMan 662-2 or some of the mammoth Woods cams that end up in many BIG motors....
While I have a lot of tweak'n & test'n to go, I am very happy with the results.
I still have a number of additional pics to post, but it's time to ride now so.... It's gonna be a best effort on that front.

Larger, more aggressive (steep / sharp ramp angles) cams require much stiffer valve springs 180~200+ lbs seat pressure to keep the valves from "floating" at higher RPM's.
Combine the two (steep, sharp ramps & HEAVY valve springs) and the result is much greater pressures being exerted on all of the valve train components. The lifters tend to be one of the first components to be affected by these pressures.
I'm not saying lifter failure a certainty by any stretch of the imagination. What I am saying is that it can and does happen. Additionally, because I like to take LONG rides (week ~ 2 weeks, 3~6k miles), I do not want to be in the middle of BFE and meet Mr Murphy.
If you do not actually "tour" on your "Touring Bike", then it may not be a big deal. Mine is build to ride, last, and be FUN in the process.... As far as I'm concerned, mission accomplished!

A SuperTrapp is a SuperTrapp. The one I found that could reasonably easily be attached to the BoarZilla headpipe just happens to be one of their universal Race mufflers.
It's tuneable. It allows one to tune the torque curve up / down the powerband. It is quite likely that the SuperTrapp "cost" me some topend HP, but it certainly saved some db's too. I will continue to test, tweak, & tune because that's what I enjoy.

Phil thanks for taking the time to keep us in the loop on your build, very informative for those of us less informed I enjoy following these types of projects. Sounds like you're quite
capable of dealing with the occasional person trying to wizz in your corn flakes.

I can't believe I just saw this thread for the first time today!
That may be the best looking dyno chart I've ever seen as it translates to what has to be an extremely fun bike to ride!
Phil and Ed...pretty good combo there
Did you say 40-45 MPG though....
I was gonna ask you a few more questions about your choice of cams, why your dyno dick isn't as big as Joe's and blah blah blah but I think I'll just call you instead....
Let me know when you are going to Ed's again? Tomorrow? I want to see this bad *** real time dude.
