    Hey JR, what’s your reasoning for the carby conversion?

    Simplicity really.
    And, the effort and costs required to run a full EFI wiring harness and associated accoutrements does not outweigh the small benefit of slightly better fueling.

    Thats a good idea too Krash. 

    Obviously it'll be a bit of work, but ill suss it all out when its time. The ACRs dont sound too hard, wiring it to the starter relay is a brilliant idea. Ill probably get a staunch starter motor too help on that front. 

    Ill start a thread once the project starts. 

    John , I had very high cranking pressure, with an 01 twin cam dyna, I had manual comp releases, always worried as every hole u put in the head weakens it. but electric comp preferable to manual, but I never had a problem. and used stock starter, had it fail about every 20 to 30,000k just rewired got parts from HD, one time at drags in a three day championship race, starter failed on third qualifier, a guy from HD dealer took my starter home rewired, bought to track next morning so I made first elimination. stock starter good! I did lot of k's. ( ride to race , ride home )

    I fitted the Fuling premium lifters in my TC when I did the cam swap, not cheap about 400 from Rollies. 
    The easy start cams are a good suggestion, save a bit pf mucking about, especially if you are going to swap out cams anyway.
    Cheers

    I have seen S&S 585 cams in a 2016 CVO Breakout Pro Street. Guy had them put in for "bad starting" and I retuned it for him to suit the S&S cams.

    Just 2 weeks ago that was

    So that is an obvious option , assuming there is a suitable cam in the S&S "easy start" range for your planned build.

    Dont know much about the TCs so havent really been following the  ins and outs, but have been considering a TC for the next project. A take off SE 110 has popped up as an option. 

    How does the SE 110 stack up against other TCs? Are there any inherent issues? Does that motor have any improvements over regular 103s etc?, or just bigger pots?

    Itd be running a carb setup.

    John, just noted you will run a carb, ( I like them too ) is there a carb manifold to fit the 110 SE? also what carb do you think you will use?
    myself I have ran a lot of different carb's on HD's over the years, one I really liked and it worked well on my TC 88 was a CV51 that I was lucky enough to get a race tunners kit for. that bike flew. sold it with 100,000 up and still going, new owner compeleatly rebuilt bike, just so he knew it 100%.

    I might be wrong, but I think just about any TC manifold could be used? 
    I was thinking the Mikuni HSR 45 kit, which includes a manifold for TC's. It mentions it works in any TC application that still uses stock height cylinders. I'd be confirming this is the case with the 110 motor before dropping the cash for it though!

    Looking at the specs, since the 96", the only difference has been bore size. They've all been the same stroke, so it should be okay.

    John , personally I don't think the Mic 45 would flow the air a motor that size can use.
    I was just asking about manifold for carb, as with the late sporty EFI heads I have, the factory machined the intake side of the heads to give EFI TB room, but there is no carb manifold that would fit, lucky Hammer makes one from Billit. they said a lot of Drag racers in USA use those heads on rigid mount motor sporty's with carbs, so they made manifolds up. if you like Mikuni I think the 48mm could be a better choice but I've seen them tuning Miks and hard to get AFR perfect all over, it's also hard to get AFR perfect all over with CV carb too but can fit a Thunder jet, I have a Bobby Wood 435 rebel CV uses Holley main jets so go up in 1 thou increasements to fine tune, also has a special needle. but I think it flows more air than my sporty motor needs. just have to see. but I just have a little 88 cubic inch ( same bore same stroke ) not a big 110 cubic inch. but if not worried about riding it hard, might be ok.

    You could very well be right Krash, 45 was just what I had in my mind as being ballpark. The 45 seems to work across a huge range of big cube donks, and across motors that are pretty worked in the head department.

    had my engine fully re-built by Hoody.
    had done about 33'000 km's.
    crank was fckn average, .008" and .015" run out, just put another SE crank in with the Timken conversion.
    SE 263 cams, work really good in the 110's.
    SE 58mm throttle body
    heads machined by Hoody
    tuned by Lushy, 134 HP & 122 TQ
    nice to ride now.

    In the end don't matter what carb you use as long as your happy & it run's sweet !!
    Australia's quickest street bike run's a carb, stock 1999 Twin Cam dyna frame, no air shift just foot shift, no ignition cut out I watched him do the pass at Sydney International Dragway , 9 seconds 138mph trap speed s&s carb, Daddyracer56 was the rider.
    ralphski should go to drags see if you can beat the time & speed, think the bike had about same HP your dyno showed. should give it a go.

    Please tell me the a HD dealership did this work lol. All it needed was the Strategy 621 update and the bike would whirr into life like it was on a jumperpack.

    I was made aware of the cam change to S&S 585 easy start after the event ! Cam swap done by local indy..

    And yes I was aware of "strategy 621" but by then it was a well done deal ! No point in going there then !

    Guy wanted cam change anyways I presume , always the way... As I have said already , I like the CVO 255 cam myself

    Never had any starting problems with my own (now sold) CVO Breakout with 1800 Pro Upgrade kit neither ( strategy 621 not required on that model year !)

    I think the 110 is a very strong motor if all the right goodies go into it, I have only had mine for approx 6 months but the original owner put a stage 3 SE kit in from new before delivery was taken. The bike had only done 8500km when I took delivery and I was lucky to purchase a extended 3 year warranty which covers the upgrades as it was all done in house. The bike itself goes pretty hard with the 259SE cams the torque is mid range which is really nice. The torque is about 110 and the HP is approx 108 going on the book specs. I haven't actually had it on a dyno yet since I owned it but am going to do that in the next couple of weeks to see what it actually puts out. so according to the book the kit itself comes with forged 10.5.1 comp kit, 259E cam kit ,new pushrods, heavy duty clutch spring , new gasket kit.

    Do the later 110s have the same dreaded lifter problems as whats been reported on the older engines

    Not so much,the 110 is the best place to start if that donk will fit in your frame and it fits your budget!
    There's a list of things you do to a 110 and these guys here some of them know it.
    A 120 ??

    I've killed 2 sets in 8,000km's

    2 other mates have also lunched them, one had less than 1000km's!

    Both times for me dealership didn't even blink an eye, it's a weekly occurrence for them.

    In Feb my warranty runs out so It's as good excuse as any to go to town on the engine :)
