    I know many of you are right up on this so.

                                           I own a 2014 Dyna Wide Glide @ 8400 Ks .I am looking to the next step in performance. I ride mainly 1 up, touring and spirited riding, I don’t rev much above 4000 as the standard motor seems to run out of power after that. My rev range is usually from 2200 to about 4000.I do around 3 long trips each year and the rest is social riding and runs of a day or two. Long trips I might have some luggage and be 1 up , the over nighters I might have a combined weight of perhaps 160 kilos.( 2 people minimal gear)I don’t want a drag motor but would definitely like to clean the  heads up and make it breath better and work a lot more  efficiently.Im not sure if I need to rebore or go bigger pistons etc but lets for starters get your ideas on head work and go from there. I would like to use a RB Racing LSR 2 into 1 exhaust , a hi flow air cleaner and will get a TTS Master tune to tune it. I envisage approx a bit over  100 HP and about the same torque should be achievable. Reliability and useability is more important to me than outright dyno figures.

    My idea was less than .600 valve lift possibly an S S 585 cam or Andrews 37 or 57 or equivalent cams. I would like to utilise roller rockers in the build if possible.

    Am I on the right track? I have quotes from BranchOkeefe and also Dunnperformanceheads for heads or should I just take the bike to HD and fit a whineing sparrow stage 1V? ( was quoted over 5large)

    Do I get cams to match the heads or heads to match a cam? Is my cams mentioned a good choice? Any one had experience with BranchOkeefe heads? I had Branch heads on my last wide glide .Also a good mate had  an XR 1000 sporty back in the day and they came stock with heads from them So I sort of went for a familiar name to start.

    Was going to make this a serious refit  to last a while.Also looking for something different to what I see around.

    Ill be planning this for around march or april as we get shitloads of rain here and not much riding is possible.perfect time for a refit

    I know theres some seriously knowledgable people on here. Many thanks.

    I'm no engine builder and not even qualified as a hack but I recently went through a similar thought process to you. If you have a builder in mind, chat to them about what you need (which isn't necessarily what you think you want). Otherwise you'll get a heap of opinions, confusion and perhaps mix matched parts. For example 585 cams like 10.5 compression and would benefit from headwork. Andrews 57 cams are 0.560 lift and would benefit less from headwork and they don't like compression above 10.1.

    Lots of ways to skin a cat and spend your money. 

    I upgraded my top end from 96 to s&s 107 cylinders with matching cp forged pistons, 585 ezy start cams, s&s pushrods, fueling lifters. Engine is at 10.5 compression. No headwork or change to throttle body or injectors but it's an option down the track if I want more. No need for roller rockers or the like. The bike should give me exactly what you're after (useable midrange torque) and hopefully be pretty reliable. Still running the engine in on it's first couple hundred kms and doing some tts vtuning along the way.

    Since you're already at 103 ci, a cheaper and arguably more reliable option that will still give you a healthy increase in midrange torque is adding the andrews 57h cams and nothing else besides adjustable pushrods. If using an independent shop, this'd cost about $1k and you'd vtune it.

    With that exhaust, if you fit a cam like a 54H Andrews and get it tuned properly, you will have 100hp or very near. Very cheaply.

    Sorry to hijack thread for a sec.

    Lushy, I am after similar midrange with a 107 build. Looking at the supertrapp supermeg 2-1 as it's supposed to be one of the quietest performance pipes. Have you seen how they go in terms of midrange performance and noise?

    I have also just gone through this. As with Fatbat, I am not an engine builder either and can only really comment on what I did with my 07 Fatty.
    I went with a kit from Dunnperformance. 103 heads, forged pistons, ported/polished heads and put the Andrews 55h cams in. I had V&H bigshots on for the first 150ks but have now gone to the Supertrapp Supermeg 2:1.
    Currently the bike has 500ks on it and I am about to change the oil. Yeah work in the way of my play.
    What's it like???
    Yeah it gets up and goes. I had a thread on here a while back and some people agreed with the 55's others did not. I already had them so they went in. If after a while I don't like them they can come out (put in adjustable P rods) so no big deal there.
    Yep it has to get to 2500rpm but after that it keeps pulling. I haven't really pushed it and will a bit later. Once again some say ride it like you stole it straight off.
    Absolutely happy with the Supermeg 2:1. Started off with closed cap etc but now have 12 discs and open end cap. Has a deeper sound with a rumble. I will continue to muck with this a bit but I will get it tuned once I get to about the 1500 - 2000k mark. The nearest dyno is about 2 hrs away.
    Keith Dunn was full of info and very easy to talk to as I called him a couple of times. Really helpful with pricing and postage into country (if you know what I mean :). The guy I got to put it together mentioned Branch heads etc but was really impressed with Keith's work. He also uses RB 2:1s and reckins they are great. Saw them ona custom Fatty and looked great.
    Apologies for the long post, but I am pretty damn happy with the result. Can't wait to get it dialed in.
    Cheers. Bucky

    Hey Bucky...what sort of costs were involved in this build???

  • Bucky15

    Sparra, that was 3.5k without me doing any work. Not including the pipe.

    Hi Bucky. Thanks for the info. I also used bestway customs as you did but only put 250kms on mine so far. Are you coming back to Canberra to have Jason look over things? If so let me know. Also where did you buy your supertrapps from?
    Sorry for hijacking thread.

    Fatbat,
    Jason was v helpful with everything. Would definitely go back there. Getting over there now is the problem with Xmas close and all.
    361098425788
    Search the above number in US Ebay. Best deal I found and here inside 7 days.
    Robb, after speaking with Jason at bestway customs re 2:1 and taking into consideration everything etc, I went with the supertrapp. On all accounts a very solid pipe. Would have loved to have used RB but don't need any heat re the noise.

    106/107 with 585's work well together Fatbat, you'll be happy with it. It's what I have and I'll be doing heads and TB in the winter for a bit more get up and go

    Hi daggs. Yeah im pretty happy so far. What exhaust and tuner are you running on yours? I've just got myself a supertrapp 2-1 pipe and will hopefully install over the weekend. Have you adjusted your spark timing as part of your tune?

     Will also consider heads, throttle body and injectors down the track. What will you get?

    Had mine tuned by Lushy, he did a fantastic job as always
    I'm running short shots at the moment coz I still love the look of them and they sound and perform pretty good with the baffles I made for them.
    I have a screaming eagle pro super tuner.
    Looking at maybe fitting a D&D bobcat next year as its about the only 2-1 I like the look of

    I'll probably get Mark Hood to work my heads and bore my TB and go up a size with the injectors too

    Update ,
    ordered a Pipe and air cleaner.
    Didn't go with either Supertrapp or RB Racing
    I had a Suppertrapp on my last Widey anyway so a change is cool.
    Now looking at Cams and tuners.
    Cams I have some pretty solid ideas of where Im headed ,just really a matter of which brand ,Ill replace the cam bearings also.
    Still undecided about which Heads to go for.
    Dunne definitely provide good customer service and ideas and feedback and seem to "Want" my business that's for sure. Seems a great guy to talk to .Pretty much looking to him for a kit I reckon at this stage probably easier in the long run.
    BranchOkeefe obviously have decades of experience .Obviously are renowned porters
    Really Underwhelmed by the local guys. Never heard of Jerry branch . Never heard of Keith Dunne nor Steve Cole.
    Two business with Dynos in Cairns seem to only use Screaming Eagle Tuners.
    One told me a dyno tune isn't necessary as it "Only offers a piece of paper, They just flash a canned Map" which isn't what I want to hear. That might be cool for a Screaming Eagle stage 4 kit but Im gonna drop a load of parts on there desk that they haven't ever heard of before.
    Which I have sourced and purchased myself because its what I want. So I cant see any joy coming from them.
    I would ask those of you that know is the Screaming Eagle Tuner , either flavour, a full featured one that allows individual AFR settings to be altered?
    I wanted to go with a TTS
    I can see what's going to happen. Ill probably buy any tools I don't have to do this update and do the fucking thing myself.
    Im not daunted by EFI. I do my own engineering on trucks with Cummins and Cat engines.
    Any other things like clutch springs and , throttle bodies or injectors ,adjustable pushrods I should also add to the equation?
    Bores need honing? I would think so with new pistons if I go a Kit , is that right?
    I plan to get this done before the 16 k service is due.
    The bikes just topped 10 k
    Thanks again for any advice.

    Mate I did the lot from Keith Dunn. Cyls, Heads, pistons, cams etc.
    All good and running really well.
    Yep easy to deal with, helped out with the receipt for total cost when he shipped through customs too......
    Cheers.

    Thanks for ya input Bucky,
    I reckon Ill head in the same direction.
    I reckon I might fit it up myself.
    May as well get on with it and look forwards

    Good luck with it mate. Let us know how you get on.
    The only problem with mine is it won't start. Because I'm not on the FKN thing! Too much time at work.
    I love riding more than ever now with the upgrade.
