Big Bore kit

    So as I modify everything I own, the 883 is next to get enhanced. I have spoken to my local HD dealer and the quote for the kit is approx $3,800 (I'm happy with that). That's everything supplied and fitted, plus dyno tuning.
    I asked the dealer about doing head works/porting and increasing the compression while the heads were off and the reply was that I'd have to take the parts from them to get the works done myself by someone else, and then return them to the dealer for fitment. My question therefore is, should I go with the dealer and not bother getting any extra work done other than the big bore kit fitted, or should I look at other workshops that specialises in HD who might do a better and potentially a more personalised job?

    Is the Hammer kit a better kit than the HD kit? Other suggestions?

    I'm on the Gold Coast, so if anyone has recommendations, please post below. BTW I have no issues with the dealer at all, just asking for help/insight.

    The Harley kit is good, but it's limited to 1200cc's whereas the Hammer & S&S kits go up to 1275 and/or 1250.  Why not go all the way and get a 1275 kit.  Look on the Hammer and S&S sites, you may be able to get a kit that has ported heads.  Or you may be able to get your 883 heads modded.  I recall there were benefits in doing that over just installing 1200 heads.

    I had the SS kit on my old 883c, only advice is don’t use the gaskets it comes with and have someone tune it properly, mine was still mapped to an 883, from a shit motorcycle workshop won’t name. Anyway it leaked oil, I’ll show u pics of tune front and rear cylinder had different tunes cause it to leak. Got the better gaskets and proper tune it went so much better, it is 100% worth it done right.

    all I can say is, Harley dealers, sell Harleys. but not many have hi performance tuning experience go to an expert. what state are you in?
    or hi performance engine building experience.
    we have a number of people in Australia that could get your bike to go quick & reliable but I have no idea at what it would cost. if a tight budget leave it.
    myself I'm about to start tuning my old sporty next week in Sydney, might take a month but I'm doing whole thing ( not me personally ) gear box flywheels barrels pistons rods heads cams. carb air kit. see what happens. I'm building to ride a lot and test it at the track. but I'm not shooting for any numbers. see how it goes after it's finished.
