After collaboration with the master, Doc himself...
I present for your viewing pleasure....
Let me start off by saying that I've read/researched until I was cross eyed!
My requirements where respectable power where I ride most often... with as much stock reliability as possible. After riding a '99 King that I'd worked over last year (big bore, ported heads, gear driven Andrews 26's, PCIII) I found that after I purchased my RGU in January, well... to put it bluntly... the stock epa 103" is a PURE SLUG. (IMHO, of coarse!) I don't abuse my machine, but when I roll the throttle... I'm asking for "it," and "it" needs to deliver. The RGU was so bad so that, I'd often ride my king.... even though I'd purchased my "dream bike." On top of that... the heat from the cat made me wonder how Harley ever sold even one of these bikes in the summer!
A call was made to Doc Weaver, and I expressed my concerns.
Although he told me that the 4" Rineharts weren't the best performing slip ons, he understood my decision for "the sound."
The cam suggested wasn't even on my radar. He described it as the equivalent to the 255, just moved to the right a bit. "It won't rip your arms out of their sockets, it's got a nice smooth pull all the way through," he told me.
Given his advice, that's the direction I went. I ordered the cams and accomplished the cam swap, along with the big sucker, Fullsac x pipe, and 4" Rineharts the weekend prior to the appointment on the dyno.
On March 9th, a buddy of mine and myself had "our day" at Doc's tuning performance. He tuned my bud's that morning, and mine was tuned after lunch. The TTS had been purchased prior to arriving at Docs... I payed for nothing more than the tune.
The man is a MASTER.... plain and simple. He's got a complete understanding of the twin cam, and what is proven to work. He's been doing this for a very long time and can prove factually what works and why. Opinionated? Heck, yes.... he is! He's very passionate about what he does. He's been silenced on this forum, as well as others. I for one feel that it is a crying shame, and a tragic loss of a wealth of valuable information.
If your contemplating any engine modifications to your ride... you owe it to yourself to at least call and discuss it with Doc. He doesn't manufacture anything. Yes, he sells the TTS Mastertuner, and can defend why he considers it the premier tuner on the market. I traveled 987 miles round trip for the privilege of having my bike tuned by Doc. Now that I've experienced his passion for excellence, I'd not hesitate to travel twice the distance.
Your decision for your motorcycle, money, and time is up to you.
I'm completely confident that "THE MAN" has given me the motorcycle that Harley Davidson intended for the RGU to be!
