    Question: does the SE 131 engine fit into the 2019 Fat Bob? Just dreaming but curious for a future project maybe. Anyone done this?
    TIA

    I have no idea how much that donk costs... BUT if I was dropping a LOT of cash on a motor it would always be an S&S and not a SE.

    common misconception
    the SE 128 and 131 kits have a good track record
    plenty of problems with the S&S 124's on the US forums if you dig, haven't read much on the 143's
    mate of mine recently went the S&S 110 from Rollies and had major problems
    They refunded his money and he went 107, but was a whack out of pocket for labour, gaskets, oil filters and oil and dyno time

    Fark me.... Bloody quality seems to have dropped.  I'm out of date though as my experience is in the old 96" Evo S&S motors back in the day.

    I guess its all about Warrenty and Support if you have problems...Who has the better aftersales reputation then.

    I’m thinking no one in Aus had done this as it’s just plain stupid. 
    I realise Mesmer posted it as a bit of a rhetorical question but the bigger question is 
    What do you want to achieve?
    I’d be thinking there are cheaper, more reliable ways to peel the rubber off your tyres.

    Hi Ratbob, indeed it was at this stage just a rhetorical question. From my research it seems that there are differences between the engines for the Fat Bob and those of the Touring models. Seems like the casings are different and also, surprisingly, the internals. Even though they may both be 114ci they are quite different. Hence the 131 wont fit the Fat Bob.

    That being said I've seen photos of a 131 being installed in an FXDR. And I kow of one in a Low Rider S so presumably it can be done?

    Why would I want to do it? Well, firstly torque and secondly I'd like to have the 120hp of the bike engine. The 114 is good to a point but it does run out of steam at the top end of the rev range. At this point it's totally just an idea, but maybe at some point in the future, funds allowing. Of course if it doesn't fit then it's back to the drawing board.

    Anyone want to buy my 690 Duke to fund this? LOL

    Just had a reply from my local Harley dealer, apparently the 131 will fit! But is it worth the 10K!!!

    If 120hp is your number you want you dont have to go the whole hog of getting a motor , there are several kits that will get you there/ close. Get onto a reputable builder and listen to their advice.

    There are builders and assemblers, some people simply bolt things together other ensure the correct tolerances are adhered to.

    I am well aware of that
    I know of 1 shop in the US that preheats these cylinders to 200° in torque plates to simulate running conditions and does a minimal bore for true, fitting os pistons
    It was the only way they could guarantee they would not be coming back

    Yeah Mesmer it can be a long and trying process. We’ve all heard the success and horror stories, I admire your drive if you give it a go.
    I assume the 10grand they quoted you was for the case engine alone, not installed and tuned, even if it was I’d take Tussuck’s crazy advice and go turbo, jeeze they look mean too and come sell time, you can pull em off.

    You could get to 120hp without a kit
    the right cam and pipe and a decent tune would get you there

    Yeh I've seen bikes with only a stage 2 hit those numbers mate. But if you are determined to spend $10K, a company called Leading Edge in the states make a 151" kit.
