Thanks for the input and insight.
I should have posted the carb question on the carb forum so I will. "Keihin FCR carbs are the shiznit!" It might be easier to keep my pipes/jetted carbs as a set since the bike runs like doom. Second set of pipes equals second set of carbs?
For the record, I claimed my short TORs "have a lot of bark". There is no reference to any niceness associated with that bark. Actually, I am not very fond of the bark at all. I have known only these pipes and their bark since delivery from the dealer(carbs jetted and dyno'd). I need different pipes without compromising my current setup so I can switch at will if required. I did land a used set of America long, slashcut stock silencers as a backup in case the laws change, and they have. The OEM sewing machine is not an option. Gradually drilling out these stock pipes while rejetting may be. A direct replacement with rejet would be ideal.
I think the 790cc will struggle to match the warm, low-end rumble and growl produced by much larger displacements. The natural low-midrange characteristics of the 790 are more apt to create a classic bubbling racing tone. Since these engines like high revs, pipes should sound authentic in 5K rpm range. I find my short TORs hum/buzz loudly at a mid-high midrange tone. Off the line they are loud, low yet raspy with splash of bark. Either way, sound is always a personal preference.
There was a series of videos awhile back that showed an early model America with long TORs and one with Bubs. The Bubs were nice but it was hard to tell when the engine was revved as high as it was. The long TORs on the 790cc sounded very retro British without that bark. They were honky-throaty and would likely sound nice while riding "needles up" without being too over-bearing. They were however lacking substantial warmth in the low range. Does anybody think these pipes are too loud?
I am not a fan of excessive exhaust noise. Residential respect calls not only for reasonable pipes (people accept motorcycles are naturally loud) but also an attitude in riding approach. Putting along to get through these sensitive areas shows that you are trying to be considerate and that goes a long way to keeping the peace and freedom we ultimately are seeking. Always be a good neighbor: crack a bottle not the throttle.
Pipes anyone?
