The problem is that Harley doesn't claim the EFI sportster make anymore power by listing higher crank numbers (at least for the 1200s because the 883's do make more power due to new cams). So either the numbers harley listed are too low (small chance of that since they would love to advertise more power) or there was a 0% loss in the drivetrain (impossible). So that just leaves a dyno chart that isn't exactly right, or the bike that was dynoed is stage 1 and not stock. The 70/73 would be typical for a stage 1 bike. I even posted the dyno chart of another EFI bike (63 hp) that was much more reasonable.

 

come on!! get real.. first thing i really dought you will see all of us carbed guys in your rear view..all they did was add efi..they didnt chage the heads and cams and any other kind of work..yes the efi bike will start easier and be easier on feul,but they arent any faster..personally i like having a carb..when something goes wrong with my fuel system i can fix it myself i dont need to pay a dealer to figure it out first..i guess this super fast efi sportster thing must be a sales pitch for you..

 

I do understand what you are saying 1200C. I also agree that there is indeed a discrepancy in dyno results. However, I ride these bikes on a daily basis. I can literally "feel" the difference in pull between a stock 06 1200 and a stock 07 1200. Plus, I have been on both sides of the 1/4 mile run off (won with the 07 and lost with the 06... same model (C) and same riders). I will freely admit that I have not had enough experience running these models once they have been modified.... For these results I remain dubious.But at this point... based on my own experience... I believe that the EFI is a better platform to build from.

 

Yes Ace... the true sales pitches are always the most useful

 

really i thought that salesman were always b/s'ing people..you must be one of a kind

 

lol.. no... I may still be proven wrong on this one... But I do tend to base my opinions on personal experience. I haven't just "heard" that EFI is an improvement... I have actually experienced it.

 

well in that case ill take my bike to the dealer tommorow and trade it in on an 07..im sure the difference will be enough to make me have to hold on the the grips twice as hard as i do now..

 

same displacement... better fuel distribution... If you make similar modifications to your new bike, I have little doubt that the results will be incrementally better. But I have already said that I have only run stock bikes. I don't claim any experience/known improvement after upgrades.

 

take it light bro.. im just trying to make my point..i got your point....im just good at being a jerk..im totally sure the efi bikes run great..thats why they changed them to efi(that and the epa)..but without doing new heads and cams or other engine changes the power cant be all that much different..and yes i agree with you that the 07 will have a snappier throttle response..im old school and will stay with my carbed bike until i have no choice...

 

right on bro... I respect that.... Also your bike is is one bad looking machine! If I had it I wouldn't trade it either... I still have much work to do on my stock 07. I love all Harleys... Even those old leaky AMFs lol... If my dad would have kept his old '77 FXS, I would trade my 07 for it without hesitation. I honestly don't believe that EFIisa "huge" improvement, but I do think it's an improvement. Is it an improvement that's worth selling an 06 and taking the loss for?.... Uh... No
