    I think they will be ok. Just bought another dealership earlier this year.

    Harley is in trouble because of business decisions.

    Take the newest bike, which from a platform to move forward on and target the new riders is great, the Livewire. But starting at $30k.

    A well loaded Zero Motorcycle is half that. And for a little over $6k an entry level bike can be had.

    The electric motorcycle will catch on especially for the urban rider. They go short distances, don’t have to worry about filling, can charge overnight on 110, and don’t have to visit gas stations.

    But this rider is attracted to the urban, young lifestyle. You won’t sell them a $30k Harley.

    And I don’t think Harley brand loyalists (aka HOG riders) want an electric bike. I mean how can they run straight pipes and make noise with an electric motor?

    I thought you were buried in Glenwood Springs? I am pretty sure I visited your grave site.

    It's said there was a winter storm, and they couldn't carry Ol' Doc up the hill to the graveyard, so they buried him down below, and when spring came they went back to move him up to a proper grave and couldn't find where they put him before.

    It's also rumored his body was sent back to Georgia, and he's buried in an unmarked grave in the family cemetery.

    Either way, the legend lives on....but I digress....

    That bike riders who rev their engines unnecessarily are nuisance attention hogs or, in the case that a bike rider needs to rev their bike to keep it from stalling, they are slackers in the area of bike maintenance. Making obnoxious noise is not a need. It is a choice.

    I spent about three weeks in Arizona use my buddies place in Mesa as a homebase and we rode four days a week out of the house doing about a 250 mile loop.

    The heat don’t keep me in the house just like the cold in the winter does not keep me in the house in Minnesota

    Exactly! I was gonna say that but I'd get accused of being one of those knuckle dragger types that have to rev their engines all the time and then of course the South Park reference. No shortage of Harley haters around here.

    Let the accusers accuse. And the South Park episode was funny.
    To me, riding has never really been about caring what others think.
    It’s the most selfish thing I do.

    It gets old though. I don't rag on any motorcycles or riders. I'm a true enthusiast, I've several bikes, from crotch rocket to dual sport and everything in between. This is why I have a hard time with the haters.

    In general, groups that disturb others with loud noise, whether that been shooting ranges, airports, concerns, loud car stereos, motorcycle, cars with open exhaust, etc tend to not be liked so much.

    Maybe the solution is to minimize the disturbance to others?

    And honestly, straight pipes of a Harley are for image only. It takes a well designed exhaust system to typically see any horsepower gains. Some of the loud, poor exhaust systems actually cause power and/or torque losses.

    There is a performance gain in getting air and fuel in and letting air out . You also have to adjust the fuel to air ratio or you will blow and engine or load one up . How many drag cars have you seen with a muffler ?

    And yet somehow something like a Ducati V4 S Steetfighter can make 208hp and still meet noise emissions requirements.

    https://www.motorcyclecruiser.com/2018-harley-davidson-cvo-road-glide-hp-and-tq-numbers/

    +3hp on a 97hp / 860 pound bike doesn't change performance one bit.

    But to answer your question how many drag cars have I seen with mufflers... plenty. The street classes normally require a muffler.

    https://www.nhra.com/nhra-drags-street-legal-style/street-legal-style

    Check with your local NHRA member track for its requirements, but generally, you can expect to be expected to provide proof of the following:

    • A valid driver's license
    • Valid vehicle registration and insurance
    • DOT-approved street legal tires
    • Seat belts
    • Muffler
    • If using nitrous, nitrous-oxide bottles must be stamped as meeting DOT 1,800-pound standards *Requirements may vary

    Most harley riders dont care about power & torque loss, they`re wanting the BIG sound from that V-Twin. Most harley riders are clueless on what it takes to make REAL power & torque out of a harley.

    Do not forget that there is more to it than adjusting air and fuel. If the whole package is not designed for it, then there will be very small gains on top and you will kill the mid range. Seen it a lot on the dyno. Most Harleys will see nearly the same gain on top without loosing the mid range by leaving half of the baffle in place. It does increase the noise level, but not like an open pipe. It is all in the combination of cams, compression, heads and intake system.
