You see many guys lately starting threads about changing stock cams to EV27s. Many others going with 2 into 1 pipes. Read on and learn...

If you have the MM EFI then it won't be that easy or that cheap I'm afraid, unless your local Indie is an MM expert.

if you're interested I have the complete take-off setup from my "stage2" 98 road king (that was MM injected)....ECM already flashed to "stage 2", throttle body with the red injectors, and the SE-3 cam that harley was installing.

shoot me an offer (i love to barter), as its just taking up room in my toolbox right now.

That is the best factory performance and reliable setup, it was in my bike when I got it and no issues. The SE-3 is a EV27, no piggyback tuner needed, no dyno tune and still keeps the M&M within it's range

Yes, pulls better but you sacrifice higher engine speed during cruising, it is alot of work to replace that pulley.

Much simpler to change the compensator. I went from 25T to 21T on my TC88, which really woke it up! That's an increase in rear wheel torque of 19% for pocket money, however not everyone's cup of tea.

To RKD's original question, a change of cam and, if the ignition is separated from the MM EFI, a change of ignition module. A stage 1 is popular, but completely misses the main problems of liberating EPA restricted vehicles. EPA Harleys suffer from less than ideal cam and ignition timing, to help get them through both emissions and noise tests. The ignition module will give a much better timing curve, along with the improved breathing of a new cam. I was very happy with my EV27 (probably the most popular cam in here), but would probably chose an EV13 if I were to do it again, as I now ride 2-up along with the kitchen sink!

Anyone have real life experience with a compensator swap combo that worked well that coul be useful in a 1998 FLHTCI with the MM efi? I am considering changing mine to hopefully get a little more power in my mule! Any ideas....? One suggestion to me was to maybe add a tooth or two but go with the more torquey EV13 cam....saying it would balance out the higher rpm issue but give me a bit more? I thought the other way around would be the way to go....EV13 cam....and a 24 tooth compensator. HELP lol
