    @mobear66 the lloyds hpt cams gives up a little lbs of tq in the lower rpm range. theres a big dip in the dyno graph with them. not to mention having to clearance the head. dont think you have to do that with kyles cams & no dip in the graph either

    @busaman04 that maybe but I will take my 119.5/115 all day. Timing wheel takes care of the low end. Clearancing the head is not accurate only the cam carriers are clearanced to allow the cams to slip in the carrier.

    I've never met Kyle but I have watched the threads about him with interest over the years. I sure am impressed by what he's done and continues to do. He seems to be very innovative and is always finding things unique to him and his company to help coax a little more reliable power from these motorcycles.

    He's another one I hope to meet someday just to shake his hand and thank him to his face.

    That is not true. If you install the Lloyd's drop in cams you don't need head work. Modifying the heads works much better when you enlarge the bore size and increase the compression. I haven't read a post on this forum of guys that installed the drop in cams needing to get head work too.

    I assume that the HPT cams have more lift and this is why you either need the cam carriers modified for more clearance or use the Lloyd's billet cam carriers that accept his HPT cams and need no cam clearance. I was told by Kevin at Southern Motor Werks that unless you wind the rpm's past 4,000 rpm's a lot when you ride you'd be better off buying the Lloyd's drop in cams.

    The only reason for clearencing is to get them in the cam carriers that is it. IMO Its got all needed in the lower gears and has a nice reponse in the higher gears no down shift needed. I ride around a lot in the 3k range in traffic and when i yank on it i have to hold on. Like most things its all about preference and your style.

    Please get your sh!t straight before you go shooting it around.
    Someone tells a guy "to do the HPT cams you have the clearance the cam carriers" and the guy hears "THAT REQUIRES HEADWORK".



    To do HEADWORK you would have to take the heads OFF. To get the heads off you would have to take the engine OUT OF THE BIKE.

    The first step is to understand what a cam carrier is. It would also be a good idea to understand what it means to do headwork and how that is very different than clearancing a part.

    Someone like KMC will clearance a bunch of cam carriers and take them on the road with them. If you get HPT cams installed they simply trade carriers with you. Later, they will clearance all the take-off carriers (yours) and replenish their supply of pre-clearanced carriers. They still charge you for the labor of clearancing the carriers, but it's already done to save time.

    @Half_Crazy Those steel frame models can really pack stupid power!! Are you close to 200hp? There is a cat out here in Vegas that is like 197ish on a hammer.

    No, not me.... Peter has 200+ on his supercharged Hammer.

    I'm content to live in this neighborhood.

    There's a reason why Indian is flourishing and Victory is going the way of the dinosaur...

    Bam bam. This is a 2 yr old thread. Victory is a legend. Created and never imitated.
    It’s not our fault........ Those who seek to stand on their own and stray from the crowd that PolarASS made the decision they did because they can’t market worth a crap.
    Flourishing ....... Indian is not. Surviving ? More like it for now. If Indian were to take a stance and copy a Victory more than a Harley then I for one as many here would find a way to forgive but not forget.
