A friend of mine was talking about the 48/72 Sportsters and the motors in them (1200). I chimed in asking that with the new FI motors, can you tune up the 883 to be comparable to the 1200 in the Sportster models. He and I are old school carb guy's and don't know anything about the FI motors/the how well the PC can tune them or how far you can take the computerized motors etc.
So we started looking at some engine specs and here is what I found on-line. Not sure if they are correct. ??
883:
Bore-3"
Stroke-3.81
Comp-9.01
H.P-53/48ftlbs torque
1200:
Bore-3.5"
Stroke- 3.81
Comp-10.1
H.P.-65/72ftlbs torque
Then the question(s) came up:
1. "Is there a difference in the cam profile/lobes/duration etc between the 883/1200 or just the heads/cylinders/pistons."
2. "Can the jugs (cylinders)/cam/heads/pistons be changed out to a 1200 series w/the FI motors and is it worth it."
3. "Or, can the 883 actually be tuned (pipes/tuners/air intake etc) with-in reason to the 1200's H.P/torque range without changing out the jugs, cam etc?"
We said we didn't know and would ask.
Reason this conversation took place is I was looking at the 48/72 on-line from the HD site and then the Iron caught my eye, but it has the 883.
So, we went to HD dealer looking at a few bikes and I looked at/sat on all three and liking them all.
Thanks for the help, hope this makes since,
Jim
