    This is true in the way that I am always looking to improve what is that I have. It isn't true in the sense that I just don't up and change things just for the sake of changing them. When I change something it is derived from a perceived necessity. Best thing about this is that it won't happen until the 117 is ready to go in or shortly before.

    The other option is to put on an SNS super G carb, they work very well
    and will give you all the power you can handle with out the expensive conversion to EFI.

    I ran a super G on my 117/124 and it was enough carb for that bike, I also added in a Zippers Thunderjet to help with transition from pilot to main, this allows you to run a bit smaller pilot jet for fuel economy and eliminates the dip for fuel demand when going WOT..

    Going this route you can determine that the bike will perform as you like without the expense of the EFI, or the costly tuning and mapping, rewire, etc.

    Can it be done, sure, anything can be done but JMO it's not necessary to get a shit ton of power with a good smooth riding bike with a carb.

    Gotta agree with the guys saying stay with a carb...the Delphi EFI may be a better system,but the maintenance is a heck of a lot more costly if you need to replace a regulator and filter or injector...pumps aren't too bad in price...(not to mention the cost of conversion)..if you're thinking of going EFI route because the CV51 is obsolete... SNS G and Mikey Rooney 48 are really good carbs and a lot cheaper to tune...and not hard at all....Seat of the pants you're not going to feel much of a difference, if any, to a well tuned carb and an EFI system JMHO:)...Maybe your wallet will still be thicker in your pocket if you stay carb and you save a lotta work....;)

    Yep I'd bet a mr45 would be even better drive ability on the road

    Yeah,I was thinking that too...a Super E or 45 Mik would give better throttle response and drive ability for a street/touring bike,but I don't know how big he's going with the engine and how much head work...The G and 48 would be more suited to a max effort top end big inch motor...
    If I don't get this damn EFI straightened out on mine soon I can see a S&S E and an IST going in... lol

    I ran an E and G on the 117 and the difference wasn't huge on the dyno
    got a bit more HP up top but really how often are you hanging it out there past
    5000 RPM on a Harley, so for driveability around the town the E was better,

    Same for the 42 vs 45 when it was a 95, little more up top that was about it.

    Ran the G on the 124 as the E is too small, also had a woods cv 51 known
    as the 505 Rebel on it, that was a great carb, but it's not cheap...

    I have thought pretty hard about what everyone here had to say and also on HTT. I came to the conclusion that I am going to stay with a carb system. And that I will consider an S&S with one thunder jet installed.

    Look at all the old boys on here and see if they are still running carbs.

    Nope.

    They are running EFI systems on newer bikes.

    I'm still running a carb on my 2003 Heritage Springer and plan on leaving it stock. To me there is no advantage to change it as long as my carb is working so think your making a wise decision. The only thing I have to do is pull the choke out when its cold which is no biggie. Been over MTN passes and she does fine.

    buddies 113 is an SNS carb Super E with T jet, pulled the EFI.

    I think it's a wise move Johnny..

    Laser I remember he test drove a new bike.
    Just know I'm never going backwards to a car bed bike.
    They quit making them.

    They quit making lots of perfectly good stuff to make way for new ideas. Gotta keep those engineers employed. Maybe he should convert to ABS and modernize the braking instead of the EFI swap? :) Just stirrin' $%#@up...

    Just like they quit making carbed cars.
    They Polute more. Like letting raw fuel out without as much burn.
    And its easier to hook up a computer to a EFI and adjust everything.
    Than to take the carb apart and adjust it.

    If all you did was RACE. I might agree with you. But over all.
    EFI is the way to go.

    Just like on the newer bikes and cars. Electronic drive is nicer than cable drive.

    They outlawed carbs on boat motors much earlier than motorcycles.
    If you sit and watch a carbed boat motor run, you can see raw gas get blew out into the water. You don't see that with efi .

    You can stay in the past and get left behind. Or you can come forward to the new technology.

    Look people used to die from TB. As time went on they found a cure for it.

    Yeah, overall EFI is better for reliability and cleanliness. I use my bike as a toy to blow off stress, so the carb does not bother me too much. I like my cars fuel injected, start better in the cold, warm up quicker, and no smells like you used to get on the old motors. Just messin with ya.

    Nothing wrong with either, however taking your hard earned resources
    to covert a running carb bike to EFI just isn't worth the $ and time, carbs work
    they just don't work the way your Presbo Obozo wants them to work thats why
    we have EFI, the government.

    So CB you do whatever your president tells you to huh LOL
